    Description: Earthquake Early Warning Systems (EEWSs) represent a technical-scientific challenge aimed at improving the chance of the population exposed to the earthquake shaking of surviving or being less affected. The ability of an EEWS to affect the risk and, in particular, vulnerability and exposure, may determine serious legal responsibilities for people involved in the system, as scientists and experts. The main question concerns, in fact, the relationship between EEWSs and the predictability and avoidability of earthquake effects-i.e., the ground shaking affecting citizens and infrastructures - and the possibility for people to adopt self-protective behavior and/or for industrial infrastructures to be secured. In Italy, natural disasters, such as the 2009 L’Aquila earthquake, teach us that the relationship between science and law is really difficult. So, before EEW’s become operational in Italy, it is necessary to: 1) examine the legislative and technical solutions adopted by some of the international legal systems in countries where this service is offered to citizens; 2) reconstruct the international and European regulatory framework that promotes the introduction of EW systems as life-saving tools for the protection of the right to life and understand whether and how these regulatory texts can impose an obligation on the Italian legal system to develop EEWS; 3) understand what responsibilities could be ascribed to the scientists and technicians responsible for managing EEWS in Italy, analyzing the different impact of vulnerability and exposure on the predictability and avoidability of the harmful event; 4) reflect on the lessons that our legal system will have to learn from other Countries when implementing EEW systems. In order to find appropriate solutions, it is essential to reflect on the opportunity to provide shared and well-structured protocols and creating detailed disclaimers clearly defining the limits of the service. A central role must be recognized to education, because people should not only expect to receive a correct alarm but must be able to understand the uncertainties involved in rapid estimates, be prepared to face the risk, and react in the right way.

    Description: Decades of geochemical monitoring at active crater lakes worldwide have confirmed that variations in major elements and physico-chemical parameters are useful to detect changes in volcanic activity. However, it is still arduous to identify precursors of single phreatic eruptions. During the unrest phase of 2009–2016, at least 679 phreatic eruptions occurred at the hyperacid and hypersaline crater lake Laguna Caliente of Poás volcano (Costa Rica). In this study, we investigate the temporal variations of Rare Earth Elements (REE) dissolved in Laguna Caliente in order to 1) scrutinize if they can be used as a new geochemical tool to monitor changes of phreatic activity at hyperacid crater lakes and 2) identify the geochemical processes responsible for the variations of REE concentrations in the lake. The total concentration of REE varies from 950 to 2,773 μg kg−1. (La/Pr)N-local rock ratios range from 0.93 to 1.35, and Light REE over Heavy REE (LREE/HREE)N-local rock ratios vary from 0.71 to 0.95. These same parameters vary in relation to significant changes in phreatic activity; in particular, the (La/Pr)N-local rock ratio increases as phreatic activity increases, while that of (LREE/HREE)N-local rock decreases when phreatic activity increases. REE concentrations and their ratios were compared with the variations of major elements and physico-chemical parameters of the lake. Calcium versus (La/Pr)N-local rock and versus (LREE/HREE)N-local rock ratios show different trends compared to the other major elements (Na, K, Mg, Al, Fe, SO4, and Cl). Moreover, a higher loss of Ca (up to 2,835 ppm) in lake water was found with respect to the loss of Al, K, and Na. This loss of Ca is argued to be due to gypsum precipitation, a process corroborated by the mass balance calculation simulating the precipitation of gypsum and the contemporaneous removal of REE from the lake water. The observed relations between REE, changes in phreatic activity, and the parameters commonly used for the monitoring of hyperacid volcanic lakes encourage investigating more on the temporal and cause-effect relationship between REE dynamics and changes in phreatic activity at crater lake-bearing volcanoes.

    Description: Coastal and ocean island volcanoes are renowned for having unstable flanks. This can lead to flank deformation on a variety of temporal and spatial scales ranging from slow creep to catastrophic sector collapse. A large section of these unstable flanks is often below sea level, where information on the volcano-tectonic structure and ground deformation is limited. Consequently, kinematic models that attempt to explain measured ground deformation onshore associated with flank instability are poorly constrained in the offshore area. Here, we attempt to determine the locations and the morpho-tectonic structures of the boundaries of the submerged unstable southeastern flank of Mount Etna (Italy). The integration of new marine data (bathymetry, microbathymetry, offshore seismicity, reflection seismic lines) and published marine data (bathymetry, seafloor geodesy, reflection seismic lines) allows identifying the lineament north of Catania Canyon as the southern lateral boundary with a high level of confidence. The northern and the distal (seaward) boundaries are less clear because no microbathymetric or seafloor geodetic data are available. Hypotheses for their locations are presented. Geophysical imaging suggests that the offshore Timpe Fault System is a shallow second-order structure that likely results from extensional deformation within the moving flank. Evidence for active uplift and compression upslope of the amphitheater-shaped depression from seismic data along with subsidence of the onshore Giarre Wedge block observed in ground deformation data leads us to propose that this block is a rotational slump, which moves on top of the large-scale instability. The new shoreline-crossing structural assessment may now inform and improve kinematic models.

    Description: The entanglement between active tectonics and karst systems is well-known in the literature. Karst systems are sound recorders of continental deformation in terms of brittle structures and seismic features and have been successfully used as markers for reconstructing tectonic stresses and assessing preferential directions of increased permeability in oil and gas fields. Karst systems could also be exploited to evaluate the past activity of faults bounding karst hydrostructures, thus providing useful data for the assessment of the seismic hazard of a specific area. In this work, we look into the complex relationship among karst development, recent tectonics and groundwater flow, which appear to be strongly interconnected with each other, to assess the activity of faults bounding karst hydrostructures. We focused our attention on an active karst area located in the Mesozoic and Cenozoic carbonate reliefs of the Italian central Apennines. In this context, the morphological and morphometric features of the karst landforms (dolines, dry valleys, and cave entrances), identified with geomorphological surveys, and their mutual relationship with fractures and fault segments, identified employing geostructural analysis, document stasis and deepening events in karst evolution. Such events are related to changes in the groundwater table and the consequent variation of the paleokarst base level associated with the Quaternary fault activity. A comprehensive evaluation of the evolution of karst systems at local and regional scales, considering the hydrogeological influence on base levels, allows us to use karst landforms as a proxy to unravel fault activity and evolution in Italy and in other similar karst environments.

    Description: We use a novel technique named global-phase seismic interferometry (GloPSI) to image the lithospheric structure, and in particular the Moho, below two parallel north-south transects belonging to the GANSSER network (2013–2014). The profiles cross the Himalayan orogenic wedge in Bhutan, a tectonically important area within the largest continent-continent collision zone on Earth that is still undergoing crustal thickening and represents a challenging imaging target for the GloPSI approach. GloPSI makes use of direct waves from distant earthquakes and receiver-side reverberations with near vertical incidence. Reflections are isolated from earthquake recordings by solving a correlation integral and are turned into a reflectivity image of the lithosphere below the arrays. Our results compare favorably with first-order features observed from a previous receiver function (RF) study. We show that a combined interpretation of GloPSI and RF results allows for a more in-depth understanding of the lithospheric structure across the orogenic wedge in Bhutan.

    Description: Submarine hydrothermal systems along active volcanic ridges and arcs are highly dynamic, responding to both oceanographic (e.g., currents, tides) and deep-seated geological forcing (e.g., magma eruption, seismicity, hydrothermalism, and crustal deformation, etc.). In particular, volcanic and hydrothermal activity may also pose profoundly negative societal impacts (tsunamis, the release of climate-relevant gases and toxic metal(loid)s). These risks are particularly significant in shallow (〈1000m) coastal environments, as demonstrated by the January 2022 submarine paroxysmal eruption by the Hunga Tonga-Hunga Ha’apai Volcano that destroyed part of the island, and the October 2011 submarine eruption of El Hierro (Canary Islands) that caused vigorous upwelling, floating lava bombs, and natural seawater acidification. Volcanic hazards may be posed by the Kolumbo submarine volcano, which is part of the subduction-related Hellenic Volcanic Arc at the intersection between the Eurasian and African tectonic plates. There, the Kolumbo submarine volcano, 7 km NE of Santorini and part of Santorini’s volcanic complex, hosts an active hydrothermal vent field (HVF) on its crater floor (~500m b.s.l.), which degasses boiling CO2–dominated fluids at high temperatures (~265°C) with a clear mantle signature. Kolumbo’s HVF hosts actively forming seafloor massive sulfide deposits with high contents of potentially toxic, volatile metal(loid)s (As, Sb, Pb, Ag, Hg, and Tl). The proximity to highly populated/tourist areas at Santorini poses significant risks. However, we have limited knowledge of the potential impacts of this type of magmatic and hydrothermal activity, including those from magmatic gases and seismicity. To better evaluate such risks the activity of the submarine system must be continuously monitored with multidisciplinary and high resolution instrumentation as part of an in-situ observatory supported by discrete sampling and measurements. This paper is a design study that describes a new long-term seafloor observatory that will be installed within the Kolumbo volcano, including cutting-edge and innovative marine-technology that integrates hyperspectral imaging, temperature sensors, a radiation spectrometer, fluid/gas samplers, and pressure gauges. These instruments will be integrated into a hazard monitoring platform aimed at identifying the precursors of potentially disastrous explosive volcanic eruptions, earthquakes, landslides of the hydrothermally weakened volcanic edifice and the release of potentially toxic elements into the water column.

    Description: During the lithospheric buildup to an earthquake, complex physical changes occur within the earthquake hypocenter. Data pertaining to the changes in the ionosphere may be obtained by satellites, and the analysis of data anomalies can help identify earthquake precursors. In this paper, we present a deep-learning model, SeqNetQuake, that uses data from the first China Seismo-Electromagnetic Satellite (CSES) to identify ionospheric perturbations prior to earthquakes. SeqNetQuake achieves the best performance [F-measure (F1) = 0.6792 and Matthews correlation coefficient (MCC) = 0.427] when directly trained on the CSES dataset with a spatial window centered on the earthquake epicenter with the Dobrovolsky radius and an input sequence length of 20 consecutive observations during night time. We further explore a transferring learning approach, which initially trains the model with the larger Electro-Magnetic Emissions Transmitted from the Earthquake Regions (DEMETER) dataset, and then tunes the model with the CSES dataset. The transfer-learning performance is substantially higher than that of direct learning, yielding a 12% improvement in the F1 score and a 29% improvement in the MCC value. Moreover, we compare the proposed model SeqNetQuake with other five benchmarking classifiers on an independent test set, which shows that SeqNetQuake demonstrates a 64.2% improvement in MCC and approximately a 24.5% improvement in the F1 score over the second-best convolutional neural network model. SeqNetSquake achieves significant improvement in identifying pre-earthquake ionospheric perturbation and improves the performance of earthquake prediction using the CSES data.

    Description: The oceans are a fundamental source for climate balance, sustainability of resources and life on Earth, therefore society has a strong and pressing interest in maintaining and, where possible, restoring the health of the marine ecosystems. Effective, integrated ocean observation is key to suggesting actions to reduce anthropogenic impact from coastal to deep-sea environments and address the main challenges of the 21st century, which are summarized in the UN Sustainable Development Goals and Blue Growth strategies. The European Multidisciplinary Seafloor and water column Observatory (EMSO), is a European Research Infrastructure Consortium (ERIC), with the aim of providing long-term observations via fixed-point ocean observatories in key environmental locations across European seas from the Arctic to the Black Sea. These may be supported by ship-based observations and autonomous systems such as gliders. In this paper, we present the EMSO Generic Instrument Module (EGIM), a deployment ready multi-sensor instrumentation module, designed to measure physical, biogeochemical, biological and ecosystem variables consistently, in a range of marine environments, over long periods of time. Here, we describe the system, features, configuration, operation and data management. We demonstrate, through a series of coastal and oceanic pilot experiments that the EGIM is a valuable standard ocean observation module, which can significantly improve the capacity of existing ocean observatories and provides the basis for new observatories. The diverse examples of use included the monitoring of fish activity response upon oceanographic variability, hydrothermal vent fluids and particle dispersion, passive acoustic monitoring of marine mammals and time series of environmental variation in the water column. With the EGIM available to all the EMSO Regional Facilities, EMSO will be reaching a milestone in standardization and interoperability, marking a key capability advancement in addressing issues of sustainability in resource and habitat management of the oceans.

    Description: On May 14, 2019, a strong Mw = 7.6 shallow earthquake occurred in Papua New Guinea. This paper explores for the first time the analysis of total electron content (TEC) products measured for 6 months by GPS antenna onboard Swarm satellites, to detect possible seismo-ionospheric anomalies around the time and location of the above-mentioned earthquake. The night-time vertical total electron content (VTEC) time series measured using Swarm satellites Alpha and Charlie, inside the earthquake Dobrovolsky’s area show striking anomalies 31 and 35 days before the event. We successfully verified the possible presence of concomitant anomalous values of in situ electron density detected by the new Chinese satellite dedicated to search for electromagnetic earthquake precursors [China Seismo-Electromagnetic Satellite (CSES)-01]. On the other hand, the analysis of VTEC night time measured by Swarm Bravo shows gradual and abnormal increase of the VTEC parameter from about 23 days before the earthquake, which descends 3 days before the earthquake and reaches its lowest level around the earthquake day. We also analyzed the time series and tracks of other six in situ parameters measured by Swarm satellites, electron density from CSES, and also GPS-TEC measurements. As it is expected from the theory, the electron density anomalous variations acknowledge the Swarm VTEC anomalies, confirming that those anomalies are real and not an artifact of the analysis. The comparative analysis with measurements of other Swarm and CSES sensors emphasizes striking anomalies about 2.5 weeks before the event, with a clear pattern of the whole anomalies typical of a critical system as the earthquake process is for Earth. A confutation analysis outside the Dobrovolsky area and without significant seismicity shows no anomalies. Therefore based on our study, the VTEC products of Swarm satellites could be an appropriate precursor aside from the other measured plasma and magnetic parameters using Alpha, Bravo, and Charlie Swarm and CSES satellites that can be simultaneously analyzed to reduce the overall uncertainty.

    Description: Forecasting earthquakes is a challenging scientific task, due to the intrinsic complexity of the problem, as well as to the limited size and different accuracy of available observations. During the last decades increasing efforts have been devoted by geophysical research in an attempt to answer the following fundamental questions: 1) Which are the physical processes that take place in the Earth crust that are relevant for an earthquake to nucleate? 2) How can we observe, describe and model them statistically and physically? Although a clear univocal picture is still missing, a large amount of data and long-term observations accumulated over the time, as well as new methodological approaches, which eventually allow for development and verification of theoretical models. Observations and physical models suggest that several processes in the Earth’s lithosphere are predictable, but after substantial averaging and up to a limit. Accordingly, earthquake forecasting requires a holistic approach, and should be posed as an integrated, multi-scale process, narrowing down the magnitude range, territory, and time of expectation, all within the limits imposed by physics and data uncertainties. The understanding of governing laws, from long-term tectonic loading and slow nucleation to rapid rupture propagation, may contribute to estimate the stress state and temporal evolution of geophysical observables around seismically active areas.

    Description: Changbai Mountains intraplate volcanism (NE China) developed above the 500 km deep stagnant portion of the Pacific slab in the last 20 Ma. The more recent activity includes a shieldforming stage (2.8–0.3Ma), the Tianchi cone construction stage (1.5–0.01Ma), and a calderaforming stage (0.2Ma-present). Detailed studies on the petrogenesis of the volcanic products between the first two stages and the possible role of geodynamics and local tectonics in controlling the volcanism, however, are lacking. Here, we present structural and whole-rock geochemical and zircon Hf isotopic data on Pleistocene dikes of the Changbai Mountains at the transition from the shield-forming to the Tianchi stage with the aim to constrain their age and the source(s) of their parental magma. The dikes represent the shallower feeding system of monogenetic cones and have a NW-SE strike, which is also the preferred strike of the major fault affecting the area and along which the Changbai Mountains monogenetic scoria cones align. The dikes have a potassic affinity and a trachybasaltic composition. Their zircon U–Pb age is 1.19–1.20Ma (Calabrian). The trachybasalts are enriched in Rb, Ba, Th, U, Nb, Ta, K, Pb, and LREE and slightly depleted in Sr, Zr, Hf, Ti, and HREE with a weak negative Eu/Eu* (δEu 0.96–0.97). Trace elements and isotopic compositions are compatiblewith anOIB-type source with an EMI signature. The calculated (87Sr/86Sr)i ( 0.705165–0.705324), (143Nd/ 144Nd)i ( 0.512552–0.512607, εNd(t) −0.58 to −1.65), and Hf model ages (TDM2) of 1768–1562 Ma suggest that the trachybasaltic dikes were contaminated by a Mesoproterozoic, relatively basic lower crust. The source of the Calabrian trachybasalts consists of asthenospheric melts modified by a subcontinental lithospheric mantle. These melts upwell from depth and stop at the crust-mantle interface where underplating processes favor the assimilation of ancient lower crust material. During the ascent to the surface along deep-seated crustal discontinuities, these magmas weakly differentiate.

    Description: Lactobacilli are the dominant members of the healthy human vaginal microbiota and represent the first defense line from pathogen infection, including vulvovaginal candidiasis. Biofilm is the predominant microbial growth form in nature, and the formation of biofilms inside the human body has important implications in health and disease. In particular, the formation of biofilm by members of the human resident microbiota is desirable, as it can improve microbial persistence and influence functionality. In the present study, we investigated the capability of 16 vaginal Lactobacillus strains (belonging to Lactobacillus crispatus, Lactobacillus gasseri, Lactobacillus vaginalis, and Lactobacillus plantarum species) to form biofilms, and we correlated their mode of growth to anti-Candida activity. L. plantarum strains were the best biofilm producers, and high variability was registered in the level of biofilm formation among L. crispatus and L. gasseri strains. Culture supernatants derived from Lactobacillus biofilm and planktonic growth were tested toward a panel of Candida clinical isolates (Candida albicans, Candida glabrata, Candida lusitaniae, Candida tropicalis, Candida krusei, and Candida parapsilosis) and their metabolome assessed by 1H-NMR. L. crispatus and L. plantarum strains exhibited the best fungistatic profile, and biofilms enhanced their anti-Candida activity; on the contrary, L. gasseri strains were more effective when grown in a planktonic mode. Biofilm/planktonic mode of growth also affects Lactobacillus metabolism, mainly influencing nitrogen and amino acid pathways, and anti-Candida activity is instead strictly related to carbohydrate metabolism. The present study underlined the strict interdependence between microbial mode of growth, metabolism, and functional properties. Biofilm formation by members of the healthy human microbiota represents a crucial issue in the field of microbial physiology and host-microbiota interactions, beyond supporting the development of new antimycotic strategies based on probiotics grown in adherence.

    Description: Marine seismic reflection data coupled with on-land structural measurements improve our knowledge about the active deformation pattern of the northern sector of the Malta Escarpment, a bathymetric and structural discontinuity in the near-offshore of Eastern Sicily. As favourably oriented to be reactivated within the Neogene Africa–Europe convergence, it is believed that the Malta Escarpment has a significant role in the recent seismotectonic framework of the Western Ionian Basin and the Hyblean foreland domain of SE Sicily, where some of the largest and most destructive Mediterranean earthquakes are located according to available historical catalogs. Offshore seismic data along with bathymetric grids illuminate the shallow subseafloor setting and allow more accurate mapping of the seafloor expression of previously identified faults in the area. The seismic interpretation and the nearfault sediment pattern analysis provide constraints on fault 3D geometries as well as on their through-time tectonic activity, suggesting also that part of the observed deformation may have been caused by nontectonic processes. Identified faults form currently an E-dipping, roughly N–S trending, and 60 km-long extensional belt deforming the seafloor with a significant displacement amount in the Ionian offshore between Catania and Siracusa. 3-dimensional parameters of faults were then used to derive expected magnitudes and their reactivation propensity. Empirical scaling relationships and forward methods point to a high seismic potential for the detected fault as well as predict the fault slip behavior according to the fieldderived differential stress. This combined analysis along with faults displacement measurements pointed out how the longest and most continuous fault could be capable of generating M 〉 7 seismic events, putting forward strong seismotectonic implications for the adjacent and densely populated Hyblean Plateau. The expected magnitude and the estimated recurrence time interval are compatible with those inferred for large historical earthquakes in the area even if other offshore seismic sources cannot be ruled out.

Pollino area (Italy) has been performed using earthquakes recorded in the area during an intense seismic sequence that occurred between 2010 and 2014. 870 local earthquakes with magnitude ranging from 1.8 to 5.0 were selected considering the number of recording stations, the signal quality, and the hypocenter distribution. P- and S-wave arrival times were manually picked and used to compute 3D velocity models through tomographic seismic inversion. The resulting 3D distributions of VP and VS are characterized by high resolution in the central part of the investigated area and from surface to about 10 km below sea level. The aim of the work is to obtain high- quality tomographic images to correlate with the main lithological units that characterize the study area. The results will be important to enhance the seismic hazard assessment of this complex tectonic region. These images show the ductile Apennine platform (VP = 5.3 km/s) overlaying the brittle Apulian platform (VP=6.0 km/s) at depth of around 5 km. The central sector of the area shows a clear fold and thrust interface. Along this structure,most of the seismicity occurred, including the strongest event of the sequence (M W 5.0). High V P (〉6.8 km/s) and high V P /VS (〉1.9) patterns, intersecting the southern edge of this western seismogenic volume, have been interpreted as water saturated rocks, in agreement with similar geological context in the Apennines. These fluids could have played a role in nucleation and development of the seismic sequence. A recent study revealed the occurrence of clusters of earthquakes with similar waveforms along the same seismogenic volume. The hypocenters of these cluster events have been compared with the events re-located in this work. Jointly, they depict a 10 km × 4 km fault plane, NW-SE oriented, deepening towards SW with a dip angle of 40–45° . Instead, the volume of seismicity responsible for the M L 4.3 earthquake developed as a mainshock-aftershock sequence, occurring entirely within the average-to-low VP /VS Apennine platform. Our results agree with other independent geophysical analyses carried out in this area, and they could significantly improve the actual knowledge of the main lithologic units of this complex tectonic area.

    Description: Dikes feed most eruptions, so understanding their mechanism of propagation is fundamental for volcanic hazard assessment. The variation in geometry of a propagating dike as a function of the injection rate remains poorly studied. Here we use experiments injecting water into gelatin to investigate the variation of the thickness, width and length of a flux-driven dike connected to its source as a function of the injection time and intruded volume. Results show that the thickness of vertically propagating dikes is proportional to the injection rate and remains constant as long as the latter is constant. Neither buoyancy nor injected volume influence the thickness. The along-strike width of the dike is, however, proportional to the injected volume. These results, consistent with the inferred behavior of several dikes observed during emplacement, open new opportunities to better understand how dikes propagate and also to forecast how emplacing dikes may propagate once their geometric features are detected in real-time through monitoring data.

    Description: Traditional tsunami catalogues are conceived as a collection of tsunamis classified by the generating cause, providing a general description of the effects observed for each tsunami. Those catalogues, even if they provide fundamental information, are not suitable for producing an exhaustive picture of the geographical distribution of the tsunami effects. In this paper we introduce the new Italian Tsunami Effects Database (ITED), a collection of evidence documenting the effects along the Italian coasts from historical times to present. The database comes forth the Euro-Mediterranean Tsunami Catalogue (EMTC) and focusses on the effects of tsunamis observed along the Italian coasts providing descriptive and quantitative information for each OP. The information reported in ITED does not only concern the effects produced by Italian tsunamis, but also those effects produced by tsunamis originated outside the Italian territory. ITED contains 318 OPs, related to 73 Italian tsunamis and to four tsunamis which occurred outside Italy. The database can be accessed through aWebApp that displays for each OP the description of effects, quantitative data (run-up, inundation, withdrawal, etc.) and tsunami intensity with the corresponding bibliographic references. The database also provides the tsunami intensity distribution along time (tsunami-history) for each site, allowing the end user to know how a place has been affected by tsunamis over the time. The information contained in ITED makes this database a useful tool to understand how tsunamis have affected the Italian territory and emphasizes the importance of studying the tsunami hazard along the Italian coasts.

    Description: Extreme environments are excellent places to find microorganisms capable of tolerating extreme temperature, pH, salinity pressure, and elevated concentration of heavy metals and other toxic compounds. In the last decades, extremophilic microorganisms have been extensively studied since they can be applied in several fields of biotechnology along with their enzymes. In this context, the characterization of heavy metal resistance determinants in thermophilic microorganisms is the starting point for the development of new biosystems and bioprocesses for environmental monitoring and remediation. This work focuses on the isolation and the genomic exploration of a new arsenic-tolerant microorganism, classified as Alicyclobacillus mali FL18. The bacterium was isolated from a hot mud pool of the solfataric terrains in Pisciarelli, a well-known hydrothermally active zone of the Campi Flegrei volcano near Naples in Italy. A. mali FL18 showed a good tolerance to arsenite (MIC value of 41 mM), as well as to other metals such as nickel (MIC 30 mM), cobalt, and mercury (MIC 3 mM and 17 μM, respectively). Signatures of arsenic resistance genes (one arsenate reductase, one arsenite methyltransferase, and several arsenite exporters) were found interspersed in the genome as well as several multidrug resistance efflux transporters that could be involved in the export of drugs and heavy metal ions. Moreover, the strain showed a high resistance to bacitracin and ciprofloxacin, suggesting that the extreme environment has positively selected multiple resistances to different toxic compounds. This work provides, for the first time, insights into the heavy metal tolerance and antibiotic susceptibility of an Alicyclobacillus strain and highlights its putative molecular determinants.

    Description: A main challenge in open conduit volcanoes is to detect and interpret the ultra-small strain (〈10–6) associated with minor but critical eruptions such as the lava fountains. Two years after the flank eruption of December 2018, Etna generated a violent and spectacular eruptive sequence of lava fountains. There were 23 episodes from December 13, 2020 to March 31, 2021, 17 of which in the brief period 16 February to 31 March with an intensified occurrence rate. The high-precision borehole dilatometer network recorded significant strain changes in the forerunning phase of December 2020 accompanying the final magma migration at the shallower levels, and also during the single lava fountains and during the entire sequence. The source modeling provided further information on the shallow plumbing system. Moreover, the strain signals also gave useful information both on the explosive efficiency of the lava fountains sequence and the estimate of erupted volume. The high precision borehole dilatometers confirm to be strategic and very useful tool, also to detect and interpret ultra-small strain changes associated with explosive eruptions, such as lava fountains, in open conduit volcanoes.

    Description: We compile existing seismic, gravity, radar and magnetic data, together with the subglacial bedrock relief from the BEDMACHINE project, to build the most detailed sediment model for Antarctica. We interpolate these data according to a tectonic map of Antarctica using a statistical kriging method. Our results reveal significant sediment accumulation in Antarctica with several types of sedimentary basins: parts of the Beacon Supergroup and more recent rifting basins. The basement relief closely resembles major geological and tectonic structures. The thickness of sediments has significant variations around the continent, and depends on the degree of crustal extension. West Antarctica has wide sedimentary basins: the Ross basin (thickness 2–6 km), the Filchner-Ronne basin (2–12 km) with continuations into East Antarctica, the Bentley Subglacial Trench and the Byrd basin (2–4 km). The deepest Filchner-Ronne basin has a complex structure with multi-layered sediments. East Antarctica is characterized by vast sedimentary basins such as the Pensacola-Pole (1–2 km), Coats Land (1–3 km), Dronning Maud Land (1–2 km), Vostok (2–7 km), Aurora (1–3 km), Astrolabe (2–4 km), Adventure (2–4 km), and Wilkes (1–4 km) basins, along with narrow deep rifts filled by sediments: JutulStraumen (1–2 km), Lambert (2–5 km), Scott, Denman, Vanderford and Totten (2–4 km) rifts. The average thickness of sediments for the whole continent is about 0.77 km. The new model, ANTASed, represents a significant improvement over CRUST 1.0 for Antarctica, and reveals new sedimentary basins. Differences between ANTASed and CRUST 1.0 reach +12/−3 km.

    Description: Thermohaline staircases are a well-known peculiar feature of the Tyrrhenian Sea. Generated by extensive double diffusion processes fueled by lateral intrusions, they are considered to be the most stable of all the staircases that have been detected in the world ocean, seeing their persistence of more than 40 years in the literature. Double diffusion leads to efficient vertical mixing, potentially playing a significant role in guiding the diapycnal mixing. The present study investigates this process of mixing in the case of the Tyrrhenian staircases by calculating the heat and salt fluxes in their gradient zones (interfaces) and the resulting net fluxes in adjacent layers using hydrological profiles collected from 2003 to 2016 at a station in the heart of the basin interior. The staircases favor downward fluxes of heat and salt, and the results of the calculations show that these are greater where temperature and salinity gradients are also high. This condition is more frequently encountered at thin and sharp interfaces, which sometimes appear as substructures of the thicker interfaces of the staircases. These substructures are hot spots where vertical fluxes are further accentuated. Due to the increasing salt and heat content of the Levantine Intermediate Water (LIW) during the observation period, a rise in the values of the fluxes was noted in the portion of the water column below it down to about 1800 m. The data furthermore show that internal gravity waves can modulate the structure of the staircases and very likely contribute to the mixing, too, but the sampling frequency of the time series is too large to permit a proper assessment of these processes. It is shown that, at least during the period of observation, the fluxes due to salt fingers do not reach the bottom layer but remain within the staircases.

    Description: Seismic activity (e.g., earthquakes, tremors) beneath volcanic areas is primarily caused by the dynamic interaction of molten rock and hydrothermal fluids with the solid host rock, by fracturing and fragmentation of the magma itself, and by tectonic processes interacting with the volcano. In addition, near-surface phenomena such as explosions and rockfalls at a volcanic edifice also produce seismic events. At volcano observatories globally, the real-time monitoring of the spatial and temporal patterns of seismic events is an essential geophysical tool to quantify the state of unrest, and forecast eruptions successfully. Seismic waveforms, earthquake catalogues and earthquake ray-path properties commonly supplement this tool to model the complex processes responsible for the earthquakes quantitatively, and to image subsurface magmatic and tectonic structures. Independent constraints provided by other disciplines such as geodesy and structural geology also significantly help scientists to understand the volcanic processes. Recent advances in earthquake recording technology, computing power and algorithms in artificial intelligence, allow processing and interpretation of large and complex multi-parametric datasets and scenarios.

    Description: Settling-driven gravitational instabilities observed at the base of volcanic ash clouds have the potential to play a substantial role in volcanic ash sedimentation. They originate from a narrow, gravitationally unstable region called a Particle Boundary Layer (PBL) that forms at the lower cloud-atmosphere interface and generates downward-moving ash fingers that enhance the ash sedimentation rate. We use scaled laboratory experiments in combination with particle imaging and Planar Laser Induced Fluorescence (PLIF) techniques to investigate the effect of particle concentration on PBL and finger formation. Results show that, as particles settle across an initial density interface and are incorporated within the dense underlying fluid, the PBL grows below the interface as a narrow region of small excess density. This detaches upon reaching a critical thickness, that scales with (Formula presented.), where (Formula presented.) is the kinematic viscosity and (Formula presented.) is the reduced gravity of the PBL, leading to the formation of fingers. During this process, the fluid above and below the interface remains poorly mixed, with only small quantities of the upper fluid phase being injected through fingers. In addition, our measurements confirm previous findings over a wider set of initial conditions that show that both the number of fingers and their velocity increase with particle concentration. We also quantify how the vertical particle mass flux below the particle suspension evolves with time and with the particle concentration. Finally, we identify a dimensionless number that depends on the measurable cloud mass-loading and thickness, which can be used to assess the potential for settling-driven gravitational instabilities to form. Our results suggest that fingers from volcanic clouds characterised by high ash concentrations not only are more likely to develop, but they are also expected to form more quickly and propagate at higher velocities than fingers associated with ash-poor clouds.

    Description: Volcano dynamics results from an interplay between internal and external processes spanning different time scales. Unravelling how such processes interact may provide key insights into the mechanisms that may lead to the destabilization of the volcanoes and eruption, a critical information to forecast hazards. Studies dealing with tidal influence on volcanoes fall within this context, yet the cause-effect relationship between tides and eruptions is still poorly understood. In the present study, we investigate the tidal influence on two nearby volcanoes, Ischia and Campi Flegrei (Italy), characterized by intense hydrothermal activity. We analyze the seismic tremor of hydrothermal origin recorded by four seismic stations between January and June 2020 by using Singular Spectrum Analysis. We detect up to five long term tidal periodicities ranging from ∼5 to ∼29 days. The results indicate that the seismic tremor is modulated by Earth tides at both volcanoes. In addition, differences in phase and amplitude modulation between the response of both hydrothermal systems to tidal forcing reveal specific features related to the tremor source and to properties of the surrounding medium. These phenomena indicate an interplay between solid Earth and the dynamics of these two volcanoes. Similar approaches on hydrothermal systems at volcanoes would contribute to better characterize the hydrothermal circulation and their evolving conditions that may represent a precursor of a new phase of activity.

    Description: Geophysical surveys in the eastern slope of the Gela Basin (Strait of Sicily, central Mediterranean) contributed to the identification of several episodes of sediment mass transport, recorded by scars and deposits of various dimensions within the Pleistocene succession. In addition to a huge failure called Gela Slide with volume exceeding 600 km3, the most studied events show volumes estimated between 0.5 and 1.5 km3, which is common to many other submarine landslide deposits in this region and that can therefore be considered as a characteristic value. In this work, the tsunamigenic potential of two of such landslides, the so-called Northern Twin Slide and South Gela Basin Slide located about 50 km apart along the eastern slope of the Gela Basin, are investigated using numerical codes that describe the onset and motion of the slide, as well as the ensuing tsunami generation and propagation. The results provide the wave height of these tsunami events on the coast of southern Sicily and Malta and can be taken as representative of the tsunamigenic potential of typical landslides occurring along the slope of the Gela Basin.

    Description: The Joint Task Force, Science Monitoring And Reliable Telecommunications (JTF SMART) Subsea Cables, is working to integrate environmental sensors for ocean bottom temperature, pressure, and seismic acceleration into submarine telecommunications cables. The purpose of SMART Cables is to support climate and ocean observation, sea level monitoring, observations of Earth structure, and tsunami and earthquake early warning and disaster risk reduction, including hazard quantification. Recent advances include regional SMART pilot systems that are the first steps to trans-ocean and global implementation. Examples of pilots include: InSEA wet demonstration project off Sicily at the European Multidisciplinary Seafloor and water column Observatory Western Ionian Facility; New Caledonia and Vanuatu; French Polynesia Natitua South system connecting Tahiti to Tubaui to the south; Indonesia starting with short pilot systems working toward systems for the Sumatra-Java megathrust zone; and the CAM-2 ring system connecting Lisbon, Azores, and Madeira. This paper describes observing system simulations for these and other regions. Funding reflects a blend of government, development bank, philanthropic foundation, and commercial contributions. In addition to notable scientific and societal benefits, the telecommunications enterprise’s mission of global connectivity will benefit directly, as environmental awareness improves both the integrity of individual cable systems as well as the resilience of the overall global communications network. SMART cables support the outcomes of a predicted, safe, and transparent ocean as envisioned by the UN Decade of Ocean Science for Sustainable Development and the Blue Economy. As a continuation of the OceanObs’19 conference and community white paper (Howe et al., 2019, doi: 10.3389/fmars.2019.00424), an overview of the SMART programme and a description of the status of ongoing projects are given.

    Description: The abundance of mantle-derived rocks and lavas, in combination with its tectonic evolution, render Mexico a perfect laboratory to investigate the chemical and the isotopic heterogeneity of the lithospheric mantle. New data on the composition of noble gases and CO2 in Mexican mantle xenoliths and lavas is reported. Our samples consist of six ultramafic nodules from the Durango Volcanic Field (DVF) and the San Quintin Volcanic Field (SQVF), monogenetic complexes belonging to the Mexican Basin and Range province; and four lavas from the Sierra Chichinautzin (SCN), a Quaternary monogenetic volcanic field located in the Mexican volcanic arc. Ne and Ar isotopes in fluid inclusions reveal mixing between atmospheric and MORB-like fluids (e.g., 40Ar/36Ar 〈 1,200). DVF and SQVF nodules record low 40Ar/36Ar and 4He/20Ne that confirm the existence of recycled atmospheric-derived noble gases in the local mantle. The averages of the Rc/Ra ratios (3He/4He corrected for atmospheric contamination) measured in Mexican localities are within the MORB-like range: DVF= 8.39 ± 0.24 Ra, SQVF = 7.43 ± 0.19 Ra and SCN lavas = 7.15 ± 0.33 Ra (1σ). With the aim of assessing the isotopic variability of the Mexican lithospheric mantle, the above results were compared with similar data previously obtained from ultramafic nodules found in the Ventura Espiritu Santo Volcanic Field (VESVF), another Quaternary monogenetic volcanic complex belonging the Basin and Range. The higher 3He/4He ratios in DVF relative to those reported for the VESVF and the SQVF are explained as reflecting different ages of mantle refertilization, triggered by the retreating of the Farallon slab (~40 Ma ago) and associated delamination slab processes. We propose that the DVF mantle was refertilized more recently (〈10 Ma ago) than the mantle beneath the SQVF and VESVF (~40–20 Ma ago). On the other hand, He-Ne- Ar compositions of SCN olivines share similarities with VESVF xenoliths,suggesting a relatively homogeneous lithospheric mantle in central Mexico. Finally, DVF and the SCN samples exhibit δ13C values within the MORB range (comparable to other values previously reported in fluid inclusions and fumaroles from Popocatépetl, Colima—Ceboruco volcanoes). While we explain the MORB-like carbon signatures of the DVF samples as the result of the above-mentioned refertilization process, the SCN signatures likely reflect either (i) trapping of isotopically fractionated CO2 derived from magmatic degassing or (ii) a mantle source unaffected by subduction-related crustal carbon recycling.

    Description: For active volcanoes, knowledge about probabilities of eruption and impacted areas becomes valuable information for decision-makers to develop short- and long-term emergency plans, for which probabilistic volcanic hazard assessment (PVHA) is needed. High-resolution or spatially extended PVHA requires extreme-scale high-performance computing systems. Within the framework of ChEESE (Center of Excellence for Exascale in Solid Earth; www.cheese-coe.eu), an effort was made to generate exascale-suitable codes and workflows to collect and process in some hours the large amount of data that a quality PVHA requires. To this end, we created an optimized HPC-based workflow coined PVHA_HPC-WF to develop PVHA for a volcano. This tool uses the Bayesian event tree methodology to calculate eruption probabilities, vent-opening location(s), and eruptive source parameters (ESPs) based on volcano history, monitoring system data, and meteorological conditions. Then, the tool interacts with the chosen hazard model, performing a simulation for each ESP set or volcanic scenario (VS). Finally, the resulting information is processed by proof-of-concept-subjected high-performance data analytics (HPDA) scripts, producing the hazard maps which describe the probability over time of exceeding critical thresholds at each location in the investigated geographical domain. Although PVHA_HPC-WF can be adapted to other hazards, we focus here on tephra (i.e., lapilli and ash) transport and deposition. As an application, we performed PVHA for Campi Flegrei (CF), Italy, an active volcano located in one of the most densely inhabited areas in Europe and under busy air traffic routes. CF is currently in unrest, classified as being in an attention level by the Italian Civil Protection. We consider an approximate 2,000 × 2,000 × 40 km computational domain with 2 km grid resolution in the horizontal and 40 vertical levels, centered in CF. To explore the natural variability and uncertainty of the eruptive conditions, we consider a large number of VSs allowing us to include those of low probability but high impact, and simulations of tephra dispersal are performed for each of them using the FALL3D model. Results show the potential of HPC to timely execute a vast range of simulations of complex numerical models in large high-resolution computational domains and analyze great volumes of data to obtain quality hazard maps.

    Description: Assessing the variations in space and time of groundwater circulation in volcanic islands is of paramount importance to the description of the hydro-geo-thermal system and implementation of hydrogeological, geochemical, and volcanic monitoring systems. In fact, the reliable reconstruction of the groundwater potentiometric surface in such composite volcanic aquifer systems can enable the identification of the most advantageous strategies for both the sustainable use of groundwater resources and the management of volcanic risk. Geographical Information System (GIS) platforms can support the integration and analysis of many spatial and temporal variables derived from monitoring of active volcanoes and the elaboration of spatially continuous data. However, open issues still affect the reliability and general applicability of common spatial interpolation methods in the case of groundwater potentiometric surfaces. This is related to the assessment of the main stratigraphic and volcano-tectonic features affecting the hydraulic head changes. With regard to the dynamically very active Ischia Island (Italy), this study illustrates a GIS-based hydrogeological approach to identify the most accurate interpolation method for mapping the potentiometric surface in complex hydrogeological terrains. The proposed approach has been applied to the existing dataset (1977–2003) stored by Istituto Nazionale di Geofisica e Vulcanologia. Based on a careful geological and hydrogeological survey, a total of 267 wells, from 5 to 250 m in depth, were processed. The data pre-processing involved four meteorological time-series data (1922–1997) and six long records of piezometric water levels (1930–1994). As a result, knowledge of the delineation of rather homogeneous stratigraphic and volcano-tectonic structures at the basin-scale has improved. Thus, new, more reliable potentiometric surfaces of the four main geothermal areas closest to the coast were produced during both dry and wet seasons. The reliability of the processed potentiometric surface was then validated by comparing the spatially continuous data with complementary field data. These findings point toward an optimal interpolation approach for representing the seasonal and areal distribution of main hydrogeological parameters in complex aquifer systems. Finally, insights into variations of hydrological behavior at an active volcanic area will foster an understanding of possible involvement of fresh and thermal waters in triggering phreatic explosions.

    Description: Gender equality is far from being reached in the areas of Science, Technology, Engineering, and Mathematics. Women in Earth Sciences still remain underrepresented although positive trends are recognized in the last decades. Dealing with gender inequalities in academia, however, is only part of the problem. As well as Earth Sciences need more women in leadership positions and decision-making committees, and more girls educated in the field, alike there are well-founded reasons for scientists to put attention to gender in a broader sense. According to United Nations, inadequate attention has been given how gender inequality drives disaster risks and impacts. The present contribution aims to broaden the gender perspective from improving underrepresentation in the workplace and breaking down barriers in research careers, to including gender in research content in an extensive sense. A paradigm shift is proposed from women in science to women in society, coping with gender-responsive disaster risk reduction and multiple gender dimensions in Earth Sciences. Counterbalancing present inequalities in the workplace, as well as applying a gender lens in all hazard-related activities is needed to cope with complex social systems in earthquake-prone areas. An intersectional approach and transdisciplinary research are needed.

    Description: Communicating scientific information about earthquakes is an important and delicate issue in countries like Italy, where seismic risk is high. Furthermore, continuous and scientifically sound communication is needed, especially in recent times when social media have amplified the risk of being biased by misinformation, fake news and conspiracy theories. For this reason, we have developed a communication strategy for earthquake science and risk in Italy, mostly based on social media. The INGVterremoti platform was born between 2010 and 2012 with the goal of increasing scientific information released to the public, and also establishing a two-way communication channel between scientists and citizens. In the past 12 years, the INGVterremoti platform has gained trust and popularity, increasing the number of involved people, which amounts today to several hundred thousand. The platform consists of a coordinated suite of social media channels and a blog-magazine, where updates on ongoing earthquake sequences and posts on scientific topics are continuously published. Our end users are mostly citizens, but also authorities and media. Special attention has been given to interactions with the public, especially on our Facebook page, in order to understand their information needs, identify rumors and fake news, particularly in areas affected by seismic sequences, and address the most pressing requests. In this paper we describe the INGVterremoti strategy, the different media that we use, focusing on their strengths and weaknesses. We concentrate on the experience, carried out in the last few years, of the publication of provisional information on ongoing earthquakes, a long-standing issue strongly requested by our followers. The INGVterremoti platform has played a fundamental role in many seismic sequences of the past 12 years in Italy, starting from the Emilia sequence in 2012, to the central Italy one, started with the deadly earthquake of 24 August 2016 and still ongoing. Besides the periods of high attention after strong earthquakes, we used the INGVterremoti social media as a tool for releasing continuous and sound information to the public, and as a way to involve citizens in the communication arena.

    Description: In this work we present and discuss new geodetic velocity and strain-rate fields for the Euro-Mediterranean region obtained from the analysis of continuous GNSS stations. We describe the procedures and methods adopted to analyze raw GPS observations from 〉4000 stations operating in the Euro-Mediterranean, Eurasian and African regions. The goal of this massive analysis is the monitoring of Earth’s crust deformation in response to tectonic processes, including plate- and micro-plate kinematics, geodynamics, active tectonics, earthquake-cycle, but also the study of a wide range of geophysical processes, natural and anthropogenic subsidence, sea-level changes, and hydrology. We describe the computational infrastructure, the methods and procedures adopted to obtain a threedimensional GPS velocity field, which is used to obtain spatial velocity gradients and horizontal strain-rates. We then focus on the Euro-Mediterranean region, where we discuss the horizontal and vertical velocities, and spatial velocity gradients, obtained from stations that have time-series lengths longer than 6 and 7 years, which are found to be the minimum spans to provide stable and reliable velocity estimates in the horizontal and vertical components, respectively. We compute the horizontal strain-rate field and discuss deformation patterns and kinematics along the major seismogenic belts of the Nubia-Eurasia plate boundary zone in the Mediterranean region. The distribution and density of continuous GNSS stations in our geodetic solution allow us to estimate the strain-rate field at a spatial scale of ~27 km over a large part of southern Europe, with the exclusion of the Dinaric mountains and Balkans.
    Description: The GNSS data analysis center described in this work is realized and maintained by different founding resources and projects, including EPOS-MIUR, the Department of Italian Civil Protection and Istituto Nazionale di Geofisica e Vulcanologia agreement (Annex A), Programma Operativo Nazionale (PON) GRINT, ILG Minerbio, MISE DGISSEGINGV 2020 agreement, Med-MFC. FP is supported by the project MUSE, funded by the Istituto Nazionale di Geofisica e Vulcanologia (INGV), within which the re-analysis discussed in this work has been developed.

    Description: The island of Ischia, an active volcanic field emerging in the western sector of the Gulf of Naples (Southern Italy), represents an archetypal case of caldera that underwent a very large resurgence related to the intrusion of a shallow magma body. The resurgence culminated with the formation of a structural high in the central sector of the island, i.e., the Mt. Epomeo block. This is bordered by a system of faults along which volcanic activity occurred up to 1302 A.D., and damaging earthquakes were generated in historical and recent time. The seismicity is located prevalently in the northern sector of the island and appears to be correlated with the most recent phase (〈5 ka) of ground movement (subsidence), although the mechanism of earthquakes’ generation is still debated. By jointly analyzing offshore and onshore data (seismic profile and stratigraphy wells, respectively) and new petrological and geochemical data related to the most recent phase of volcano-tectonic activity, we develop a geological and structural layout of the northern sector of the island. In particular, we identify the seismogenic fault associated with the historical and recent destructive earthquakes of Ischia. This fault formed in the northern sector of the island during the final stage of the resurgence.We also propose a conceptual volcano-tectonic model of the northern sector of the Ischia Island, depicting the displacement of the fault zones in the off-shore area and the possible mechanism of stress loading and release in the on-shore zone, which is mainly driven by the subsidence of the Mt. Epomeo block. Our results are crucial for evaluating the dynamics of the seismogenic structures in the framework

    Description: SOURCE utility for reprocessing, calibration, and evaluation is a software designed for web applications that permits to calibrate and validate ocean models within a selected spatial domain using in-situ observations. Nowadays, in-situ observations can be freely accessed online through several marine data portals together with the metadata information about the data provenance and its quality. Metadata information and compliance with modern data standards allow the user to select and filter the data according to the level of quality required for the intended use and application. However, the available data sets might still contain anomalous data, bad data flagged as good, due to several reasons, i.e., the general quality assurance procedures adopted by the data infrastructure, the selected data type, the timeliness of delivery, etc. In order to provide accurate model skill scores, the SOURCE utility performs a secondary quality check, or re-processing, of observations through gross check tests and a recursive statistical quality control. This first and basic SOURCE implementation uses Near Real Time moored temperature and salinity observations distributed by the Copernicus Marine Environment and Monitoring Service (CMEMS) and two model products from Istituto Nazionale di Geofisica e Vulcanologia (INGV), the first an analysis and the second a reanalysis, distributed during CMEMS phase I for the Mediterranean Sea. The SOURCE tool is freely available to the scientific community through the ZENODO open access repository, consistent with the open science principles and for that it has been designed to be relocatable, to manage multiple model outputs, and different data types. Moreover, its observation reprocessing module provides the possibility to characterize temperature and salinity variability at each mooring site and continuously monitor the ocean state. Highest quality mooring time series at 90 sites and the corresponding model values have been obtained and used to compute model skill scores. The SOURCE output also includes mooring climatologies, trends, Probability Density Functions and averages at different time scales. Model skill scores and site statistics can be used to visually inspect both model and sensor performance in Near Real Time at the single site or at the basin scale. The SOURCE utility uptake allows the interested user to adapt it to its specific purpose or domain, including for example additional parameters and statistics for early warning applications.

    Description: The general public is not aware of the full extent of the medical, economic, social, political and environmental importance of the sea. Many of us are not aware that our day-to-day actions can have a cumulative effect on the health of the ocean and seas – a necessary resource that must be protected for all life on planet earth to exist. In other words, people lack a sense of ‘Ocean Literacy’ i.e. an understanding of the ocean’s influence on us and our influence on the ocean.

    Description: Nature-based solutions (NBS) are inspired and supported by nature and use, or mimic, natural processes to contribute to the improved management of water. An NBS can involve conserving or rehabilitating natural ecosystems and/or the enhancement or creation of natural processes in modified or artificial ecosystems. They can be applied at micro- (e.g. a dry toilet) or macro- (e.g. landscape) scales. Attention to NBS has significantly increased in recent years. This is evidenced through the mainstreaming of NBS into a wide range of policy advances, including in water resources, food security and agriculture, biodiversity, environment, disaster risk reduction, urban settlements, and climate change. This welcome trend illustrates a growing convergence of interests around the recognition of the need for common objectives and the identification of mutually supporting actions – as illustrated best in the 2030 Agenda for Sustainable Development through its acknowledgment of the interdependency of its various Goals and targets. Upscaling NBS will be central to achieving the 2030 Agenda for Sustainable Development. Sustainable water security will not be achieved through business-as-usual approaches. NBS work with nature instead of against it, and thereby provide an essential means to move beyond business-as-usual to escalate social, economic and hydrological efficiency gains in water resources management. NBS show particular promise in achieving progress towards sustainable food production, improved human settlements, access to water supply and sanitation services, and water-related disaster risk reduction. They can also help to respond to the impacts of climate change on water resources.

    Description: Virtually every coastal country in the world is affected by harmful algal blooms (HABs, commonly called “red tides”). This diverse array of phenomena includes blooms of toxic, microscopic algae that lead to illness and death in humans, fish, seabirds, marine mammals, and other oceanic life. There are also non-toxic HABs that cause damage to ecosystems, fisheries resources, and recreational facilities, often due to the sheer biomass of the accumulated algae. The term “HAB” also applies to non-toxic macroalgae (seaweeds), which can cause major ecological impacts such as the displacement of indigenous species, habitat alteration and oxygen depletion in bottom waters. The frequency, spatial extent, and economic impact of HABs have all expanded in recent decades, in parallel with, and sometimes a result of, the world’s increasing exploitation on the coastal zone for shelter, food, recreation, and commerce. HABs are complex oceanographic phenomena that require multidisciplinary study ranging from molecular and cell biology to large-scale field surveys, numerical modelling, and remote sensing from space. Multi-lateral international programmes and bilateral initiatives are bringing scientists together from different countries and disciplines in a concerted attack on this complex and multi-faceted issue. Our understanding of these phenomena is increasing dramatically, and with this understanding come technologies and management tools that can reduce HAB incidence and impact. More effective HAB management is sure to be one major outcome of the growing investment in the Global Ocean Observing System. HABs will always be with us, and in the next few decades at least, are likely to continue to expand in geographic extent and frequency. Nevertheless, scientifically based management should permit full exploitation of fisheries, recreational, and commercial resources, despite the recurrent and diverse threat that HABs pose. This series of lectures is dedicated to the memory of the noted Danish oceanographer and first chairman of the Commission, Dr Anton Frederick Bruun. The "Anton Bruun Memorial Lectures" were established in accordance with Resolution 19 of the Sixth Session of the IOC Assembly, in which the Commission proposed that important inter-session developments be summarized by speakers in the fields of solid earth studies, physical and chemical oceanography and meteorology, and marine biology.

    Description: There have been spectacular advances in the field of artificial intelligence (AI) in recent years, leading to inventions that we had never thought possible. Computers and robots now have the capacity to learn how to improve their own work, and even make decisions – this is done through an algorithm, of course, and without individual consciousness. All the same, we must not fail to ask some questions. Can a machine think? Towards a global code of ethics for artificial intelligence research © Evgenija Demnievska (evgenijademnievska.com) What is an AI capable of at this stage of its evolution? To what degree is it autonomous? Where does that leave human decision-making? More than ushering in a Fourth Industrial Revolution, AI is provoking a cultural revolution. It is undeniably destined to transform our future, but we don’t know exactly how, yet. This is why it inspires both fascination and fear. In this issue, the Courier presents its investigation to the reader, elaborating on several aspects of this cutting-edge technology at the frontiers of computer science, engineering and philosophy. It sets the record straight on a number of points along the way. Because, let’s be clear – as things stand, the AI cannot think. And we are very far from being able to download all the components of a human being into a computer! A robot obeys a set of routines that allows it to interact with us humans, but outside the very precise framework within which it is supposed to interact, it cannot forge a genuine social relationship. Even so, some of AI’s applications are already questionable – data collection that intrudes on privacy, facial recognition algorithms that are supposed to identify hostile behaviour or are imbued with racial prejudice, military drones and autonomous lethal weapons, etc. The ethical problems that AI raises – and will undoubtedly continue to raise tomorrow, with greater gravity – are numerous. While research is moving full speed ahead on the technical side of AI, not much headway has been made on the ethical front. Though many researchers have expressed concern about this, and some countries are starting to give it serious thought, there is no legal framework to guide future research on ethics on a global scale. “It is our responsibility to lead a universal and enlightened debate in order to enter this new era with our eyes wide open, without sacrificing our values, and to make it possible to establish a common global foundation of ethical principles,” says Director- General Audrey Azoulay, of UNESCO’s role, in this issue of the Courier (see pp. 37-39). An international regulatory instrument is essential for the responsible development of AI, a task that UNESCO is in the process of undertaking. The Courier lends this initiative its support, by exploring different avenues of thought on the subject.

    Description: The last several years have seen a discernible shift in global priorities towards advancing the concept of sustainable development. In particular, the establishment of the post-2015 development agenda and the 17 Sustainable Development Goals (SDGs) by the UN General Assembly points towards an integrated plan towards tackling global challenges. The goals seek to protect and improve five key areas of the world including people, planet, prosperity, peace and partnership. The intent of this paper is to emphasize the vital role that transboundary water cooperation plays in global development, and to map out the relationship that this cooperation has with the other goals. Existing and emerging rules and institutions have been developed in international law to minimise, and where possible halt, negative consequences stemming from poor management of transboundary waters. SDG 6 provides for an important spotlight on improving water and sanitation, however for the context of global development it is crucial for water management to be interpreted and actionably combined with the other relevant SDGs, rather than curtailed as an individual entity. From direct linkages to indirect references, transboundary water cooperation is intrinsically connected to several other principles of sustainable development reflected in the goals and targets, including environment, energy, and food amongst others, and therefore must be viewed as an integral piece of global water management. Furthermore, Target 6.5 requires a set of two indicators in order to fully capture the importance of both integrated water resources management (IWRM) and transboundary water cooperation in the implementation of the SDGs. It is paramount that an indicator is retained solely for the transboundary water cooperation element embedded in Target 6.5. This paper advocates for an indicator that should be broad enough to reward also cooperative frameworks aimed at developing a sound system of exchange of information, and not only fully fledged IWRM systems. This is particularly important in the context of transboundary aquifers governance, where many of the cooperative frameworks being discussed are at a very initial stage. The indicator can be reviewed throughout the implementation of the SDGs, especially in relation to the quantity and quality of the information that needs to be exchanged in order to meet the indicator. UNESCO-IHP and UNECE can play an important role, together with other members of UN Water, in monitoring this much needed indicator.

    Description: Pursuant to 200 EX/Decision 5.I.B and 38 C/Resolution 19, the Director-General submits to the General Conference this information document which contains a summary of progress made in the implementation of the MAB Strategy 2015-2025 and the Lima Action Plan for UNESCO’s Man and the Biosphere (MAB) Programme and its World Network of Biosphere Reserves 2016-2025. Notably, this document includes information recently collected for and presented at the 29th session of the International Co-ordinating Council of the Man and Biosphere Programme held from 12 to 15 June 2017 at UNESCO Headquarters in Paris, France. The Man and the Biosphere (MAB) Programme Strategy 2015-2025 (“the MAB Strategy") was endorsed by the 38th session of the General Conference (38 C/Resolution 19) following a broad and transparent consultation process and the collective contributions of many Member States under the auspices of the MAB International Coordinating Council (MAB ICC). Through 38 C/Resolution 19, the General Conference also encouraged the MAB ICC, in cooperation with the MAB Secretariat, to finalize the development of the Lima Action Plan for UNESCO’s Man and the Biosphere (MAB) Programme and its World Network of Biosphere Reserves (WNBR) 2016-2025 (“Lima Action Plan”) in support of the MAB Strategy, and requested the Director-General to present to the Executive Board, at its 200th session, a progress report on the implementation of the MAB Strategy and the associated Lima Action Plan, including their contribution to the implementation and follow-up of the 2030 Agenda for Sustainable Development. At its 200th session, the Executive Board expressed its appreciation to the Director-General for the report and to Peru for hosting the Lima Congress and the 28th MAB ICC (14-17 March 2016, Lima, Peru). The Executive Board then endorsed the Lima Action Plan as adopted and endorsed respectively by the 28th MAB ICC and the Lima Congress and requested the Director-General to present a progress report on the implementation of the MAB Strategy for 2015-2025 and the Lima Action Plan to the 39th session of the General Conference (200 EX/Decision 5.I.B). The requested progress report is contained in the present document. Relevant information can also be found in the report of the MAB ICC on its activities (2016-2017) contained in document 39 C/REP/10. For ease of reference, the complete texts of the MAB Strategy, the Lima Action Plan and the Lima Congress Declaration are available in a single publication (in the six official languages of UNESCO) entitled “A New Roadmap for the Man and the Biosphere (MAB) Programme and its World Network of Biosphere Reserves”.

    Description: In 2017, the UN General Assembly declared the UN Decade of Ocean Science for Sustainable Development (2021-2030). It has entrusted IOC-UNESCO with the design and delivery of the Decade to ensure that ocean science is indeed underpinning sustainable ocean management and the 2030 Sustainable Development Agenda more broadly. Fulfilling its mandate as trustee of the Ocean Decade, as well as delivering on a growing list of additional roles, in an oceanographic space that is both expanding and increasingly crowded, establishes an important opportunity but also an overarching challenge for IOC-UNESCO. In the context of the upcoming UN Decade of the Ocean, the IOC-UNESCO agreed with the Internal Oversight Service (IOS) on the merit of conducting an evaluation of its strategic positioning within the UN system and the broader landscape of ocean-related actors and programmes, taking into account relevant enabling policy frameworks to which the work of the Commission responds.

    Description: The present document contains information on activities of the Scientific and Technical Advisory Body and the Secretariat on the UN Decade of Ocean Science for Sustainable Development (2021-2030) & the UN Ocean Conference in Lisbon. 1. The United Nations have proclaimed the Decade to support efforts to gather ocean stakeholders worldwide behind a common framework that will ensure that ocean science can fully support countries in creating improved conditions for the sustainable development of the Ocean. 2. The Scientific and Technical Advisory Body (STAB) elaborated a Strategic Framework (see also full text in annex) on engaging in the UN Decade and presented it to the 8th Meeting of States Parties in 2021. The Meeting, in Resolution 4/8 MSP, welcomed the STAB’s Strategic Framework and reiterated the need to ensure full authorization of the concerned States and respect of confidentiality for unprotected sites in all mapping processes foreseen in it. The Meeting also called on Member States to support actions in the framework of the UN Decade of Ocean Science focusing on underwater and coastal cultural heritage financially. 3. In this regard, in February 2022, a letter was sent by the Secretariat to the States Parties to raise funding for the implementation of the Strategic Framework. Pending the necessary additional contributions, the STAB is invited to determine the priorities among the actions proposed in the Strategic Framework to launch its implementation.

    Description: This item has been included in the provisional agenda of the 214th session of the Executive Board at the request of Colombia, Egypt, Kenya, Monaco, Morocco, Oman, Palau, Portugal, Serbia and Togo. An explanatory note, together with a proposed decision is attached. 1. The United Nations Educational, Scientific and Cultural Organization (UNESCO) undertakes a significant number of ocean-related activities. Founded in 1960, UNESCO’s Intergovernmental Oceanographic Commission (IOC) brings together 150 Member States. It coordinates major global ocean programmes such as ocean observing, data management, tsunami warning, develops ecosystem-based approaches to ocean management, and acts as a custodian agency for reporting on SDG targets 14.3 and 14.a. UNESCO is also the guardian of 232 marine biosphere reserves and 50 marine World Heritage sites of outstanding universal value. 2. It is within this context that UNESCO, through IOC, is coordinating the United Nations Decade of Ocean Science for Sustainable Development (“the Ocean Decade”), from 2021 to 2030. The Ocean Decade provides a common framework to ensure that ocean science can ably support countries in achieving the 2030 Agenda for Sustainable Development. This year, the Ocean Decade is high on agenda of major international summits, such as the “One Ocean Summit” (Brest, February 2022) and the UN Ocean Conference (Lisbon, June 2022), setting the stage for collective mobilization on ocean and climate issues at the 27th session of the Conference of the Parties (COP 27, Sharm El-Sheikh, November 2022) to the United Nations Framework Convention on Climate Change (UNFCCC). 3. At the One Ocean Summit, UNESCO announced its readiness to work with partners towards complete mapping of the seabed by 2030, compared to 20% currently, and to expand the work on ocean literacy, contributing to establishing more harmonious relations between humans and the ocean. These two announced ambitions complement other major UNESCO activities related to the ocean. It is relevant to note in this connection that knowledge of high-resolution ocean depth is essential to identifying the location of ocean faults, understanding of ocean currents, tides, and transport of sediments, anticipating seismic and tsunami risks, identifying natural sites and living marine resources that need to be safeguarded for sustainable exploitation. 4. The UNESCO ocean activities are conducted in line with resolutions and decisions adopted by UNESCO and IOC Member States. The second strategic objective of the UNESCO Medium-Term Strategy (2022-2029) is to “work towards sustainable societies by preserving the environment through the promotion of science, technology and natural heritage”. Its third outcome is to “enhance knowledge for climate action, respect for biodiversity, water and ocean management, and disaster risk reduction”. The IOC Medium-Term Strategy (2022-2029) focuses on ocean health, ocean-climate nexus, hazard warnings, ocean economy and knowledge of emerging ocean science issues. This work strongly contributes to the achievement of the 2030 Agenda for Sustainable Development, including Goal 14 “Conserve and sustainably use the Oceans, seas and marine resources for sustainable development”. 5. Overall, the negative impact of climate change, land-based pollution, and other stressors on the ocean and marine life is alarming. While there is considerable progress on the international arena in terms of awareness, global efforts deployed so far to overcome these negative effects are still not up to the hoped-for level. 6. The combination of the forthcoming African Conference on Priority Setting and Partnership Development for the UN Decade of Ocean Science for Sustainable Development (Alexandria, May 2022) and the UNFCCC COP 27 (Sharm el-Sheikh, November 2022) represents a unique opportunity to develop an active research agenda on ocean and climate in line with the UNESCO global priority of Africa. 7. It is suggested therefore that Executive Board adopt a decision that UNESCO continues its active involvement in major ocean related events of 2022, and supports IOC in developing necessary partnerships, further strengthening momentum of the Ocean Decade, successfully seeking extrabudgetary resources and increasing UNESCO’s overall contribution to the protection of the seas and ocean from the effects of climate change as well as the preservation of the sustainability and diversity of marine life.

    Description: A fundamental element towards attaining water security, water education has been at the heart of UNESCO’s Intergovernmental Hydrological Programme since its establishment in 1975. However, in much of Asia and the Pacific, water security remains elusive. Ensuring a water secure future for the region will require the unlocking of broader appreciation, acceptance and internalization of basic water science principles and concepts among experts and communities alike. For this, broader and more effective water education is required. For this potential to be fulfilled, reinforced human, financial and technical resources are required to deliver education, training and capacity development across large segments of society. Not only does this require the mobilization of a much larger contingent of trainers, instructors and conveners—it requires the development of new teaching and learning approaches, methodologies and curricula. This curriculum represents an invitation to tertiary-level educators as well as water managers and decision-makers to redouble efforts towards water security in Asia and the Pacific – and invitation grounded in a process that lies at the heart of UNESCO’s mission: the sharing of knowledge, experience and technologies – in this case among scientific, educational and water management communities across the region. Published with the support of the Government of Japan.

    Description: Six years after the First International Conference on “Water, Megacities and Global Change”, held on the occasion of the 21st United Nations Conference on Climate Change (COP 21), which drew attention to the significant challenges megacities are facing, and proposed the creation of the Megacities Alliance on Water and Climate (MAWAC), UNESCO’s Division of Water Sciences and ARCEAU-IdF1 decided to join forces once again to co-organize the Second International Conference on Water, Megacities and Global Change (EauMega) at UNESCO Headquarters in Paris, France and online on a dedicated platform for the conference, on 11-14 January 2022. Organized in close collaboration with the Greater Paris Metropolis and the Greater Paris Sanitation Authority (SIAAP), and with the support of many other public and private partners, this conference builds on the results of the online Pre-Conference on Water, Megacities and Global Change, which took place in December 2020. The Pre-Conference event, which brought together more than 6,000 participants, helped the organizers identify the issues requiring further consideration during the Second International Conference on Water, Megacities and Global Change by selected scientists, water operators, decision-makers, representatives of basin authorities and civil society at large. Given their size, the challenges posed to Megacities by water management within the context of climate change are of particular importance. Indeed, they raise new and specific issues that require close collaboration between scientists who advance knowledge, operators and basin authorities (public and private) who innovate technically and socio-politically, and local decision-makers who can support new, just and more efficient models of water governance, while remaining in constant interaction with civil society. Following a Call for Papers launched in late 2019, this publication is a compilation of the best scientific articles selected and peer-reviewed by the 87 international experts responsible for designing the scientific programme of the conference. Reflecting the structure of the conference with its 12 thematic sessions, the Proceedings present all the peer-reviewed articles in the following thematic chapters: • Disaster Risk Reduction; • Sustainable Development Goals & Service continuity; • Knowledge of the technical and social conditions; • Governance modalities in megacities; • Holistic water management; • Land issues and challenges; • Planning tools. • Technical and technological solutions; • Innovative initiatives at governance, technical, institutional or social level; • New water culture; • Strengthening of sustainable solidarity; The publication not only provides a state of the art on the challenges that Megacities are facing in their management of water and of the new global changes they encounter, but also presents the latest innovative and multi-disciplinary solutions being used to overcome these challenges and ensure optimal and sustainable resource management. By compiling a collection of experiences and best practices at global level, integrating the following three aspects – megacities, water and global change including climate change – it is our hope that this publication will represent a source of inspiration for other Megacities and large urban centers to overcome similar challenges and strengthen their climate resilience. By promoting fruitful exchanges and synergies among megacities, research institutions, the private sector and civil society at large, as well as inspiring further joint research studies on climate change and water-security related issues, the conference represents without doubt a fundamental building block of the Megacities Alliance on Water and Climate (MAWAC). On behalf of the Conference organizers, we wish to thank the co-conveners and partners of this second major international Conference on Water, Megacities and Global Change, as well as all the authors for their valuable contribution and their recommendations.

    Description: In every ocean, regional and national tsunami warning systems must maintain a high level of readiness so as to be able to efficiently and effectively act to provide for the public’s safety during fast-onset and rapidly-evolving natural disasters involving marine inundation of coastal areas. Because of the relative infrequency of tsunamis, but knowing that tsunamis can have widespread impact across oceans and seas, the UNESCO/IOC and its Member States have been advocating through their Intergovernmental Coordination Groups (ICGs) for the regular conduct of tsunami exercises. To maintain a high state of operational readiness, National Tsunami Warning Centres (NTWCs) and Civil Protection agencies (CPA) must regularly practice their emergency response procedures to ensure that vital communication links work seamlessly, and that agencies and response personnel know the roles that they will need to play during a real event.

    Description: International coordination of a tsunami warning system originated in the Pacific in 1968 under the auspices of the Intergovernmental Oceanographic Commission of UNESCO in cooperation with the International Tsunami Information Centre (ITIC) established on 12 November 1965 by the Intergovernmental Oceanographic Commission (IOC) and hosted by the National Weather Service of the National Oceanic and Atmospheric Administration (USA). As early as 1988, experts and Member States recognized the need to develop standardized tsunami terminology in the form of a glossary which had endorsement of the scientific community. The first edition of the Tsunami Glossary (IOC Technical series, 37, 1991) was published by IOC and ITIC and contained more than 2000 terms and definitions building on disciplines such as geophysics, oceanography, engineering and mathematics. Following the Indian Ocean tsunami of December 2004, the IOC was mandated by the United Nations to coordinate development of similar regional tsunami and other coastal hazards warning and mitigation systems in the Caribbean, the Northeastern Atlantic and the Mediterranean Sea, the Indian Ocean in addition to the Pacific Ocean. Expert groups from different regional perspectives developed a common understanding of language to be used for the development of the four regional systems. Under the coordination of ITIC, this international effort resulted in 2008 in a new edition of the Tsunami Glossary (IOC Technical Series No 85). Over the years the Glossary has been translated and is available in English (original), Arabic, Chinese, French, Indonesian, Spanish, Urdu, Korean, Tagalog, Thai and several other languages. Since 2015 changes to the content of the Tsunami Glossary are subject to the validation of the IOC Working Group on Tsunamis and Other Hazards related to Sea-Level Warning and Mitigation Systems (TOWS-WG) and subsequent endorsement by the Governing Bodies of the IOC. By this mechanism it is expected that the publication will be recognized and adopted by Member States as a validated standard in this field. The 2019 edition of Tsunami Glossary includes the definition of technical terms, and information on the expert and governance groups for tsunami warning and mitigation.

    Description: Most volcanoes on the Earth rise from the bottom of seas and oceans. Most of them do not reach the surface of sea and remain hidden to all conventional observations from surface and space. Only some of them rise above the sea level, forming islands and passing from submarine to subaerial volcanism. Volcanic islands develop in virtually all the geodynamic contexts on Earth, from mid-ocean ridges (Iceland), to intraplate (Hawaii), to volcanic arcs (Aeolian Islands). All the liquid-descent evolutive degrees of magma are finally represented, from primitive compositions up to strongly evolved rhyolite, trachyte and phonolite lavas. So, the eruptive styles of these volcanoes range consequently from mild effusions to plinian eruptions.

    Description: Italy is the land of iconic volcanoes, whose activity has been witnessed, described and portrayed for centuries. This legacy has greatly contributed to shaping the public perception of volcanoes and their impact, well beyond the national borders. Stories about famous eruptions overlap and nowadays easily mix up with the impressive footage that is readily available from ongoing eruptions worldwide. As a result, the public discourse may flatten the wide spectrum of possible phenomena into an oversimplified sketch of volcanic eruptions and their impact, where all events seem equally probable and look alike. Actual volcanoes differ in size, eruption magnitude, state of activity, eruptive style, geographical position, and each is located within a specific social and cultural context. All these elements combine in defining the consequences of volcanic activity as well as in determining the severity of the damage and the size of the impacted area. How can we convey such a complexity to the general public? Can social media contribute to raise awareness and build a more resilient society? An effective hazard communication should propose a comprehensible yet realistic description of volcanic settings and provide adequate tools to recognize and understand the specific features of each phenomenon and volcanic area. As we write, two Italian volcanoes display persistent eruptive activity, while other two are going through unrest phases that started in 2012, at Campi Flegrei, and in late summer of 2021, at Vulcano Island. Other active volcanoes (Vesuvius, Ischia, Colli Albani, Lipari, and Pantelleria) have been dormant for tens, hundreds, or thousands of years. Communication in these different contexts also require different approaches that take into account the specific needs of local communities. Social media may provide a unique opportunity to quickly share relevant news and information. Yet, this type of communication has its challenges and volcano observatories can rarely rely on expert social media managers. Sharing experiences and lessons learned is a key to ensure the growth of the volcanological community and improve its ability to connect and engage local residents. Here we discuss the online communication strategies implemented by the Istituto Nazionale di Geofisica e Vulcanologia (INGV) since 2018 to inform Internet and social media users about volcanoes, volcanology, and ongoing volcanic activity, both in Italy and abroad. We describe the internal procedures that we developed and practiced and the experience gathered so far, during both quiet periods and a few volcanic crises. Our experience confirms previous indications about the importance of a steady online presence and suggests that public interest is not always easily predictable.

    Description: Open conduit volcanoes like Stromboli can display elusive changes in activity before major eruptive events. Starting on December 2020, Stromboli volcano displayed an increasing eruptive activity, that on 19 May 2021 led to a crater-rim collapse, with pyroclastic density currents (PDCs) that spread along the barren NWflank, entered the sea and ran across it for more than 1 km. This episode was followed by lava flow output from the crater rim lasting a few hours, followed by another phase of lava flow in June 2021. These episodes are potentially very dangerous on island volcanoes since a landslide of hot material that turns into a pyroclastic density current and spreads on the sea surface can threaten mariners and coastal communities, as happened at Stromboli on 3 July and 28 August 2019. In addition, on entering the sea, if their volume is large enough, landslides may trigger tsunamis, as occurred at Stromboli on 30 December 2002. In this paper, we present an integration of multidisciplinary monitoring data, including thermal and visible camera images, ground deformation data gathered from GNSS, tilt, strainmeter and GBInSAR, seismicity, SO2 plume and CO2 ground fluxes and thermal data from the ground and satellite imagery, together with petrological analyses of the erupted products compared with samples from previous similar events. We aim at characterizing the preparatory phase of the volcano that began on December 2020 and led to the May–June 2021 eruptive activity, distinguishing this small intrusion of magma from the much greater 2019 eruptive phase, which was fed by gas-rich magma responsible for the paroxysmal explosive and effusive phases of July–August 2019. These complex eruption scenarios have important implications for hazard assessment and the lessons learned at Stromboli volcano may prove useful for other open conduit active basaltic volcanoes.

    Description: Studying a large number of volcanic eruptions is a way to decipher general characteristics related to volcano dynamics but also on external forcing influencing it, such as solid Earth and ocean tides. Many studies have tackled this tidal influence on the onset of volcanic eruptions and more generally, on volcanic activity. However, the interplay between this quasi-permanent forcing and volcanic systems is still poorly understood. With the present study, we propose to consider a global viewpoint to address this interaction. We analyzed the number of monthly volcanic eruptions and the global mean sea level between 1880 and 2009 using the Singular Spectrum Analysis time-series analysis technique to evaluate the existence of common periodicities. We found multi-decadal components of similar periodicities present in both time-series which we link to those already recognized in the polar motion. Its multi-decadal variations result in a mass reorganization in the oceans whose associated stress changes may impact processes generating volcanic eruptions worldwide. Our results show the influence of global processes on volcanic activity and open many questions to further investigate these multi-scale interactions.

    Description: Sea wave monitoring is key in many applications in oceanography such as the validation of weather and wave models. Conventional in situ solutions are based on moored buoys whose measurements are often recognized as a standard. However, being exposed to a harsh environment, they are not reliable, need frequent maintenance, and the datasets feature many gaps. To overcome the previous limitations, we propose a system including a buoy, a micro-seismic measuring station, and a machine learning algorithm. The working principle is based on measuring the micro-seismic signals generated by the sea waves. Thus, the machine learning algorithm will be trained to reconstruct the missing buoy data from the micro-seismic data. As the micro-seismic station can be installed indoor, it assures high reliability while the machine learning algorithm provides accurate reconstruction of the missing buoy data. In this work, we present the methods to process the data, develop and train the machine learning algorithm, and assess the reconstruction accuracy. As a case of study, we used experimental data collected in 2014 from the Northern Tyrrhenian Sea demonstrating that the data reconstruction can be done both for significant wave height and wave period. The proposed approach was inspired from Data Science, whose methods were the foundation for the new solutions presented in this work. For example, estimating the period of the sea waves, often not discussed in previous works, was relatively simple with machine learning. In conclusion, the experimental results demonstrated that the new system can overcome the reliability issues of the buoy keeping the same accuracy.

    Description: Volcanic and Seismic source Modeling (VSM) is an open-source Python tool to model ground deformation. VSM allows the user to choose one or more deformation sources of various shapes as a forward model among sphere, spheroid, ellipsoid, rectangular dislocation, and sill. It supports multiple datasets from most satellite and terrestrial geodetic techniques: Interferometric SAR, GNSS, leveling, Electronic Distance Measurements, tiltmeters, and strainmeters. Two sampling algorithms are available: one is a global optimization algorithm based on the Voronoi cells and yields the best-fitting solution and the second follows a probabilistic approach to parameters estimation based on the Bayes theorem and the Markov chain Monte Carlo method. VSM can be executed as Python script, in Jupyter Notebook environments, or by its Graphical User Interface. Its broad applications range from high-level research to teaching, from single studies to near real-time hazard estimates. Potential users range from early-career scientists to experts. It is freely available on GitHub (https://github.com/EliTras/VSM) and is accompanied by step-by-step documentation in Jupyter Notebooks. This study presents the functionalities of VSM and test cases to describe its use and comparisons among possible settings.

    Description: Volcanoes are complex systems that evolve in space and time as a result of their internal dynamics. These internal dynamics span both long and short time scales, reflecting the different steps for the magma to form, accumulate and evolve before being eventually erupted. All of these stages may be influenced by processes external to the volcano, although most of the evidence that has been gathered on this has considered influences on the magmatic fluids stored at crustal depths, or emerging at surface. External forcing acts either through the stress or gravitational fields that may accelerate or slow down the transfer of magma towards the surface. Changing tectonic stresses and Earth tides may induce changes in the dynamical state of volcanoes, ultimately providing the triggers that may lead to eruption. Water, which is ubiquitous on Earth, and present in its different fluid and solid envelopes, appears to play a key role, acting on volcanic systems from pore- to global-scale in various ways (hydrological modulation, ice cap loading), due to its physico-chemical properties. This Research Topic brings together contributions, which provide new constraints and lines of evidence on the nature and variety of external processes influencing activity at quiet, restless and erupting volcanoes.

    Description: This publication outlines good management practices but also explores how the protection of WWII UCH can benefit local communities and contribute to sustainable development in the region. The Pacific region covers about one-third of the total surface area of the Earth and has a long history of human migration and settlement. Beneath the waters of the Pacific Ocean lie traces of human existence that span across the centuries. These sites include ancient sunken villages, traditional fish traps of indigenous communities, and shipwrecks of missionaries and explorers. There is also a large number of shipwrecks and aircraft dated from WWII when the Pacific Ocean became the theatre of some of the fiercest battles of that time. Some of these sites are the final resting place of many lives and remain a sombre reminder of tragedies that wars bring upon people. Today many of these sites have become popular diving sites for tourists. However, some of the WWII-related UCH are slowly degrading with increasing risk of oil pollution, particularly in the event of severe storms.

    Description: The book highlights the achievements made in the management and conservation of cultural and natural heritage in Africa, reflects on the dynamic nature of this heritage, and provides recommendations to ensure its safeguarding. UNESCO is committed to working closely with African States Parties and our numerous partners to ensure that the recommendations from the conference are effectively implemented. To this end, it is essential to mobilize the necessary resources to support African institutions to achieve these recommendations. These mobilization efforts must include the participation of African youth, whose role is critical to sustainability as future guardians and caretakers of Africa’s rich heritage. It is for this reason that I call upon all readers to support sustainable development at World Heritage sites in sub-Saharan Africa for the benefit of future generations and the global community

    Description: The publication of this issue marking the relaunch of the UNESCO Courier is particularly fitting, given that it falls within the 2030 Agenda for Sustainable Development that the United Nations adopted in September 2015. This new agenda represents a turning point towards a more humanistic attitude in global development policies, relying on people’s capacities to respond to the challenges of peace and climate change through education, science and culture, which is an underlying element of each of the objectives of sustainable development. We are convinced that in a world full of limitations — in terms of our resources and our means — humanity can count on the renewable resources of its intelligence, creativity and ingenuity. This wealth, fostered by the moral requirement to respect the rights and dignity of each individual, represents an infinite source of progress. To unlock this potential, we must also help raise awareness of the creative wealth of humanity, and the Courier can contribute to this by circulating words of peace, trust and intelligence in response to the discourse of hatred, fear and rejection that currently spreads so easily on the internet and on the streets. The UNESCO Courier is also a powerful tool of this fundamental aspiration, and I call upon all UNESCO Member States and partners, and first and foremost all intellectuals, artists and experts, to make their voices heard by enriching the pages of this Courier, which has inspired so many generations of readers and will continue to do so for a long time.

    Description: UNESCO’s Global Action Programme (GAP) was launched at the World Conference on Education for Sustainable Development (ESD) in November 2014 in Aichi-Nagoya, Japan as a follow-up programme to the Decade of ESD (2005-2014). Five Partner Networks were established by UNESCO to drive implementation of the GAP on ESD and to serve as a global community of practice. A Partner Network exists for each of the GAP’s five Priority Action Areas, which are: 1) advancing policy; 2) transforming learning and training environments; 3) building capacities of educators and trainers; 4) empowering and mobilizing youth; 5) accelerating sustainable solutions at local level. This booklet contains profiles of the current 96 members (also called Key Partners) of the GAP Partner Networks. Each Key Partner is listed in alphabetical order within one of the five Partner Networks. Each profile presents the main objective of their work, their GAP launch commitment and specific activities that contribute to the GAP, as well as related website links and contact information for the organization’s focal point. Key Partners are chosen from all regions of the world for their extensive outreach capacity and their ability to innovate and have major impact on ESD. Key Partners are expected to create synergies and joint activities among themselves, as well as to reach out to a wider group of stakeholders beyond the Partner Networks. This booklet will facilitate and intensify synergies between the GAP activities of the Key Partners, and catalyze further action from other ESD stakeholders. It complements the GAP Information folder ( http://unesdoc. unesco.org/images/0024/002462/246270e.pdf) by offering additional details on each GAP Key Partner. The Key Partners’ profiles will also be made available on the UNESCO GAP Clearinghouse website: https://en.unesco.org/gap At the back of the booklet you will also find a list of UNESCO GAP Secretariat staff who can be contacted for assistance on relevant topics and activities.

    Description: Most of the activities described in this Report were conducted under the leadership of Dr Wendy Watson-Wright, the Executive Secretary of IOC during the years 2010-2014. Pending the arrival of the new Executive Secretary, Dr Flavia Schlegel, Assistant Director-General of UNESCO for Natural Sciences served as Executive Secretary ad interim from 12 January to 28 February 2015. Dr Vladimir Ryabinin started his work as the Executive Secretary on 1 March 2015. He is very grateful to Dr Watson-Wright for very ably leading the IOC during her tenure as well for her support during the transitional period. The smooth continuation of the IOC Secretariat work under the interim leadership of Dr Schlegel is also much appreciated by the IOC Secretariat and Dr Ryabinin. Like UNESCO, IOC continued to work in 2014- 2015 under the significantly reduced spending plan for the approved regular UNESCO 37 C/5 Programme and Budget (2014–2015) and with reduced staff. The Secretariat, guided by the IOC Assembly and adhering to the principles of the IOC Medium Term Strategy 2014-2021, has completed all planned tasks for the period and has achieved all assigned targets at the level corresponding to the available reduced budget

    Description: Access to water is a human right: it is vital for the dignity of each and every individual. The 2019 edition of the World Water Development Report focuses on the theme of “Leaving No One Behind”. It argues that fulfilling the human rights to safe drinking water and sanitation for all can also significantly contribute to the achievement of the broad set of goals of the 2030 Agenda for Sustainable Development: from food and energy security, to economic development and environmental sustainability. Based on the latest data, this report’s findings clearly illustrate the need to make substantial progress towards delivering on the 2030 Agenda promise of reaching the most vulnerable. The stakes are high: nearly a third of the global population do not use safely managed drinking water services and only two fifths have access to safely managed sanitation services. The intensification of environmental degradation, climate change, population growth and rapid urbanisation — among other factors — also pose considerable challenges to water security. Furthermore, in an increasingly globalised world, the impact of water-related decisions cross borders and affect everyone. At the current pace of progress, billions of people will remain unable to enjoy their right to access to water and sanitation and the multiple benefits that such access can provide. Yet, this report concludes these objectives are entirely achievable, so long as there is a collective will to do so, entailing new efforts to include those ‘left behind’ in decision-making processes. This latest Report, coordinated by UNESCO, is the result of a collaborative effort of the UN-Water Family and was made possible thanks to the long-standing support of the Government of Italy and the Umbria Region, to whom we are extremely grateful.

    Description: Among the approximately 10,000 beneficial species of marine phytoplankton in the world’s oceans today, some 200 taxa can harm human society through the production of toxins that threaten seafood security and human health. These toxins are also responsible for wild or aquaculture fish-kills, may interfere with recreation-al use of coastal or inland waters, or cause economic losses. Non-toxic microalgae attaining high biomass can also cause Harmful Algal Blooms (HABs) by producing seawater discolorations, anoxia or mucilage that negatively affect the environment and human activities. The most frequently asked questions about harmful algal blooms are if they are increasing and expand-ing worldwide, and what are the mechanisms behind this perceived escalation. These questions have been addressed in several review papers concerning HAB trends at various scales, where evidences of expansion, intensification and increased impacts of harmful algal blooms have been gathered from a selection of examples that have gained high prominence in the scientific world and in society 1,2,3,4. Eutrophication, human-mediated introduction of alien harmful species, climatic variability, and aquaculture have all been mentioned as possible causes of HAB trends at various spatial and temporal scales 5,6. Over the last 40 years, the capacity and monitoring efforts to detect harmful species and harmful events have significantly increased, thus increasing the reporting of harmful events across the world’s seas. The resulting information is mostly scattered in the ever growing literature, with data from statutory monitoring programs often not published in peer review journals, while an extensive and detailed overview of the huge amount of information on harmful species, their spatial and temporal distribution and the trends of HABs they have caused has never been attempted so far. This lack of a synthesis of the relevant data has hampered a sound global assessment of the present status of phenomena related to harmful algae. Following the lead of the International Panel for Climate Change (IPCC) consensus reporting mechanism, and to complement the World Ocean Assessment, the need has been expressed for a Global HAB Status Report compiling an overview of Harmful Algal Bloom events and their societal impacts; providing a worldwide appraisal of the occurrence of toxin-producing microalgae; aimed towards the long term goal of assessing the status and probability of change in HAB frequencies, intensities, and range resulting from environmental changes at the local and global scale. This initiative was launched in April 2013 in Paris by the IOC Intergovernmental Panel on HABs (IOC/IPHAB), and has been pursued with the support of the Government of Flanders and hosted within the IOC International Oceanographic Date Exchange Programme (IODE) in partnership with ICES, PICES and IAEA. As a first step towards a global HAB status assessment, a Special Issue of the journal Harmful Algae (vol. 102, February 2021) has been published comprising 12 papers 7-18 each presenting an overview of toxic and non-toxic HABs in a specific area of the world’s seas. The regional overviews build on existing literature and exploit the information gathered in two relevant data-bases, both incorporated into the Ocean Biodiversity Information System (OBIS).
