    Addressing the challenges of making data, products, and services accessible: an EPOS perspective (2022)
    Istituto Nazionale di Geofisica e Vulcanologia

    Publication Date: 2022-05-04
    Description: Novel measurement technologies, additional sensors and increasing data processing capacities offer new opportunities to answer some of the currently most pressing societal and environmental questions. They also contribute to the fact that the available data volume will continue to increase. At the same time, the requirements for those providing such data rise and the needs of users to access it. The EPOS Delivery Framework aims to support this endeavour in the solid Earth domain by providing access to data, products, and services supporting multidisciplinary analyses for a wide range of users. Based on this example, we look at the most pressing issues from when data, products, and services are made accessible, to access principles, ethical issues related to its collection and use as well as with respect to their promotion. Among many peculiarities, we shed light on a common component that affects all fields equally: change. Not only will the amount and type of data, products, and services change, but so will the societal expectations and providers capabilities.

    Raccontare le Sale Operative dell’INGV attraverso infografiche (2022)
    Istituto Nazionale di Geofisica e Vulcanologia
    Details
    Publication Date: 2022-06-07
    Description: AA. VV., (2020). Progetto “Sale Operative Integrate e Reti di monitoraggio del futuro: l’INGV 2.0”. Report finale. Editors: L. Margheriti, F. Cirillo, F. Guglielmino, M. Moretti. Misc. INGV, 57: 1186, https://doi.org/10.13127/misc/57
    Description: Una buona comunicazione è un’attività strategica per un istituto di ricerca come l’Istituto Nazionale di Geofisica e Vulcanologia (INGV). Ancora di più lo è quella che riguarda le attività svolte e i risultati conseguiti dalle Sale Operative, su cui si basa la sorveglianza sismica e vulcanica in Italia. Tutte le informazioni relative a fenomeni in corso potenzialmente pericolosi sono accolte con grande interesse e spesso sono oggetto di attenta valutazione da parte delle popolazioni residenti così come dalle istituzioni. In questi casi, una comunicazione efficace non è soltanto opportuna, ma necessaria a garantire una corretta informazione, a creare e mantenere un rapporto di fiducia con la popolazione e a diventare un autorevole punto di riferimento per le notizie relative alla pericolosità sismica e vulcanica. Queste premesse sono necessarie anche per poter contrastare efficacemente il diffondersi di notizie prive di fondamento, o distorte da interessi diversi dalla diffusione della conoscenza scientifica. Le attività svolte e i dati prodotti nelle Sale Operative sono fortemente diversificati. L’Osservatorio Nazionale Terremoti (ONT) gestisce la Rete Sismica Nazionale (RSN), gli Osservatori Vesuviano (OV) ed Etneo (OE) gestiscono reti di monitoraggio multidisciplinari installate su aree vulcaniche attive. In particolare, l’ONT effettua la sorveglianza sismica del territorio nazionale e delle aree limitrofe e, dal 2017, anche il servizio di Allerta Tsunami del CAT per il monitoraggio dei grandi terremoti a scala globale, con particolare attenzione al Mar Mediterraneo, nell’ambito delle attività dell’ICG/NEAMTWS; l’INGVOV effettua la sorveglianza vulcanica per le tre aree del SommaVesuvio, dei Campi Flegrei e dell’isola d’Ischia e la sola sorveglianza sismica per Stromboli; l’INGVOE svolge la sorveglianza sismica e vulcanica per l’area etnea, per Pantelleria e per le Isole Eolie, collaborando con l’INGVOV per la parte sismologica di Stromboli. Le Sale Operative sono il cuore della sorveglianza sismica e vulcanica in Italia, operano ininterrottamente grazie alla rotazione di personale specializzato, organizzata su turni H24, in ogni giorno dell’anno. Si tratta di un sistema complesso, la cui operatività si basa sulla ricezione, elaborazione, comunicazione ed archiviazione di dati che provengono dai sensori delle reti di monitoraggio, distribuite sul territorio nazionale in ragione delle diverse tipologie di fenomeni attesi. Procedure concordate con il Dipartimento di Protezione Civile (DPC) consentono di informare tempestivamente le autorità preposte al variare di specifici parametri. La sorveglianza sismica e vulcanica è garantita dal monitoraggio continuo e simultaneo di diversi parametri, e dalla loro corretta interpretazione. Ciò è possibile anche grazie ad un continuo sforzo tecnologico volto a migliorare l’acquisizione, la trasmissione e l’elaborazione dei segnali, ed alla ricerca scientifica che interpreta i segnali osservati nel quadro coerente delle conoscenze relative ai diversi contesti geologici che caratterizzano il territorio nazionale. La comunicazione al pubblico dei prodotti delle Sale è svolta attraverso la pubblicazione sul sito web dell’Istituto e delle sue sezioni di dati vulcanologici, sismologici, geodetici e geochimici. Mostrare cosa fanno le Sale Operative dell’INGV permette ai cittadini di comprendere quali risorse e competenze vengono spese per garantire la sorveglianza sismica e vulcanica del territorio. L’adozione di soluzioni innovative, con prevalenza di sintetiche rappresentazioni grafiche consente di inserire le informazioni prodotte dalle Sale nel giusto contesto, favorendo così una migliore comprensione del dato geologico e delle sue implicazioni a un pubblico di non esperti. In questo testo si illustra la progettazione e realizzazione di infografiche dedicate alle attività e ai prodotti delle Sale Operative dell’INGV.

    Description: Nel 2012, a seguito della sequenza sismica in Emilia Romagna, l’INGV decise di migliorare la sua comunicazione sulla sismicità in corso creando un blog di informazione sui terremoti. L’esigenza di avere un prodotto di immediato utilizzo orientò la scelta sulla piattaforma Wordpress119, così da poter sfruttare i vantaggi del cloud e di un hosting affidabile. In effetti, nei primi giorni di pubblicazione, il blog “INGVterremoti120” (Figura 1) ebbe milioni di visualizzazioni di pagina senza nessuna interruzione del servizio. Negli anni successivi il blog si è consolidato come punto di riferimento della comunicazione della ricerca sui terremoti e dell’informazione in emergenza sismica, arrivando a superare ventuno milioni di visualizzazioni di pagina con una media annua di oltre un milione di visualizzazioni. Sulla scia del successo di INGVterremoti, nel 2018 sono stati aperti altri due blog, uno per ciascun Dipartimento, sulla stessa piattaforma: “INGVambiente121” e “INGVvulcani122” (Figura 1), con le stesse modalità del primo anche se con finalità leggermente diverse. In particolare il blog INGVambiente, che non offre informazioni legate alle emergenze e alla comunicazione delle stesse, ha come scopo principale la divulgazione di tematiche care al Dipartimento Ambiente con la pubblicazione regolare di un post a settimana. In modo simile a INGVterremoti, il blog INGVvulcani pubblica articoli relativi allo stato di attività dei vulcani in Italia e nel mondo e approfondimenti sulla ricerca vulcanologica del Dipartimento Vulcani e sul monitoraggio vulcanico effettuato dall’Osservatorio Vesuviano e dall’Osservatorio Etneo. Grazie al continuo e tempestivo aggiornamento sull’attività in corso, è diventato riferimento costante per i cittadini dell’area napoletana, di quella etnea e delle Isole Eolie. Nel 2012, per realizzare il blog INGVterremoti fu scelto un tema gratuito presente in Wordpress chiamato “Mystique”, molto utilizzato in quel periodo. Il tema prevedeva un’interfaccia molto semplice che riportava in homepage gli ultimi articoli pubblicati in ordine cronologico. La pagina era completata da una serie di widget sul lato destro per interagire con i post pubblicati attraverso i Tag e le Categorie degli articoli e per i collegamenti a informazioni esterne (feed terremoti, social media, link siti web, ecc.). Un menù in alto nella Home conteneva l’informazione statica, composta da una serie di pagine e sottopagine. Nel 2018, per i nuovi blog di INGVvulcani e INGVambiente fu, invece, scelto il tema “Apostrophe 2” con un’interfaccia simile al tema “Mystique” ma all’epoca più moderna e attuale. Anche in questi blog la disposizione della Home prevedeva una serie di widget sulla destra e le pagine dell’informazione statica nel menù.

    Ethical Dilemmas in Geosciences. We Can Ask, but, Can We Answer? (2018)
    Istituto Nazionale di Geofisica e Vulcanologia
    Details
    Publication Date: 2018-03-01
    Description: The choices of a geoscientist while carrying out his/her activity are always accompanied by ethical implications, because they can have a strong impact on the population, the natural environment, the economy, the landscape and the cultural resources of the affected area. It is not uncommon for a geoscientist to be faced with ethical dilemmas that are problems with a difficult solution, since options to solve such dilemmas will have negative consequences. How does one make a choice in these circumstances? What is the ethical duty of geoscientists and what has to be their professional attitude? In which cases do they have the duty to take action or the duty to not act (duty of omission)? A brief review of the concepts formulated by philosophers in reference to ethics can serve to provide some answers to the above questions and to understand how geoscientists can best serve society.

    Geoethics: Ethical, Social and Cultural Implications in Geosciences (2017)
    Istituto Nazionale di Geofisica e Vulcanologia
    Details
    Publication Date: 2017-11-15
    Description: Humans are recognized as a “geological force”, capable of modifying natural environments, and in virtue of this prerogative they have an ethical responsibility towards the planet. Indeed, studying and managing the Earth system, exploiting its geo-resources, intervening in natural processes are actions that involve great responsibilities towards society and the environment, of which perhaps we, as geoscientists, are not sufficiently aware. Only by increasing the awareness of this responsibility, can we work with wisdom and foresight, and respect the balances that exist in nature while guaranteeing a sustainable development for future generations. In order to define acceptable solutions to current global challenges, we need to take into proper consideration the ethical and social aspects involved in geoscience issues. Geoethics was born to define a conceptual substratum of categories, useful as framework of reference for geoscientists, to help them develop a new way of thinking and interacting with the Earth system. Geoethics widens the cultural horizon of geoscience knowledge and contributes to orient scientists and society in the choices for responsible behavior towards the planet. The paper provides an overview of the emerging field of geoethics, focusing on theoretical and practical aspects, by showing the trajectory that has led to the current point of development of geoethics and suggesting some cues for thought for further advancements of ethical thinking in geosciences.

    The Cape Town Statement on Geoethics (2017)
    Istituto Nazionale di Geofisica e Vulcanologia
    Details
    Publication Date: 2017-11-15
    Description: Recently the interest by geoscientists in (geo)ethical aspects of geoscience knowledge, education, research, practice and communication has grown considerably. Today the topic of geoethics has gained a significant visibility within the scientific community. The IAPG – International Association for Promoting Geoethics (http://www.geoethics.org), founded in 2012, has worked to widen the discussion and create awareness about issues of ethics as applied to the geosciences. Thanks to continuous voluntary work, the respectful exchange, and fruitful sharing of ideas, the IAPG community has produced a conceptual substratum on which to base the future development of geoethics, by clarifying the meaning of the word “geoethics”, formalizing its definition, and better identifying a framework of reference values on which the geoscience community can base more effective codes of conduct and guidance. The members of the IAPG community have published various books and articles in peer-reviewed international journals, and organized numerous scientific sessions to bring geoethics to the most important geoscience conferences. Geoethical issues have been also included in the European project ENVRI-Plus, which is dedicated to the environmental and solid Earth research infrastructures. The tangible result of these efforts is that, now, many prestigious geoscience organizations recognize geoethics as a fundamental issue, worthy of attention. This result was confirmed by the high quality of content and the large participation of scientists in the six technical sessions and a panel session on geoethics organized by IAPG at the 35th IGC – International Geological Congress, held in 2016 in Cape Town (South Africa). Largely successful due to the cooperative work of different geoscience organizations (IUGS-TGGP – Task Group on Global Geoscience Professionalism; GSL - Geological Society of London; EFG - European Federation of Geologists; EGS - EuroGeoSurveys; AGI – American Geosciences Institute; AGU – American Geophysical Union, and AAWG – African Association of Women in Geosciences). The IAPG considers the 35th IGC as the scientific event that opened a new phase for furthering the concept of geoethics. In order to mark this milestone, the "Cape Town Statement on Geoethics" (CTSG) was tabled by the IAPG and reviewed in an international effort. It shall focus the attention of geoscientists on the development of shared values, policies, guidelines, strategies and tools, with the long-range goal of fostering the regular adoption of ethical values and practices within the geoscience community. The document summarizes the values, concepts, and contents developed by IAPG so far, providing a perspective for the future development of geoethical thinking. This paper addresses in detail the content of the “Cape Town Statement on Geoethics”, which is now supported officially by several geoscience organizations.

    Geoethics in Science Communication: The Relationship between Media and Geoscientists (2017)
    Istituto Nazionale di Geofisica e Vulcanologia
    Details
    Publication Date: 2017-11-15
    Description: The themes addressed by geoethics are becoming central to all scientific debate. A growing number of scientists now consider geoethics as an effective tool to increase, in the scientific community and society as a whole, the awareness of local and global environmental problems that humanity faces. Geoethics deals with ethical, social and cultural aspects related to geosciences. Geoethics addresses fundamental issues such as the prudent and sustainable use of geo-resources, management of natural hazards, defence of geoheritage as a common value to be protected and enhanced. But above all, geoethics aims to raise, in the community of geoscientists, their awareness of responsibilities in conducting scientific and professional activity. In order to extend this awareness to the whole of civil society and also to foster the recognition of the usefulness of geosciences in daily life, geoscience communication should be recognized as a fundamental activity connected with scientific and professional work, since geoscience knowledge is a tool to contribute to the construction of social knowledge for human communities. But today what is the role played by geosciences in the scientific mass culture? Are the geosciences part of a collective “cultural heritage”? Do the publishing world and media offer adequate space to geosciences? Through the analysis of two Italian case studies, the authors highlight the critical features of the relationship between geoscientists and the media and try to suggest some actions that are useful to make the relationship between these two separate fields more functional, with the goal of bringing citizens closer to geosciences and increasing the awareness of the individual and collective responsibility towards the Earth.

    Dynamic feeder dyke systems in basaltic volcanoes: the exceptional example o fthe 1809 Etna eruption (Italy) (2015)
    Nature Publishing Group
    Details
    Publication Date: 2017-04-04
    Description: In this paper, we describe the 1809 eruption of Mt. Etna, Italy, which represents one historical rare case in which it is possible to observe details of the internal structure of the feeder system. This is possible thanks to the presence of two large pit craters located in the middle of the eruptive fracture field that allow studying a section of the shallow feeder system. Along the walls of one of these craters, we analysed well-exposed cross sections of the uppermost 15–20 m of the feeder system and related volcanic products. Here, we describe the structure, morphology and lithology of this portion of the 1809 feeder system, including the host rock which conditioned the propagation of the dyke, and compare the results with other recent eruptions. Finally, we propose the dynamic model of the magma behaviour inside a laterally-propagating feeder dyke, demonstrating how this dynamic triggered important changes in the eruptive style (from effusive/Strombolian to phreatomagmatic) during the same eruption. Our results are also useful for hazard assessment related to the development of flank eruptions, potentially the most hazardous type of eruption from basaltic volcanoes in densely urbanized areas, such as Mt. Etna.

    Continuous SO2 flux measurements for Vulcano Island, Italy (2014)
    Istituto Nazionale di Geofisica e Vulcanologia
    Details
    Publication Date: 2021-06-07
    Description: The La Fossa cone of Vulcano Island (Aeolian Archipelago, Italy) is a closed conduit volcano. Today, Vulcano Island is characterized by sulfataric activity, with a large fumarolic field that is mainly located in the summit area. A scanning differential optical absorption spectroscopy instrument designed by the Optical Sensing Group of Chalmers University of Technology in Göteborg, Sweden, was installed in the framework of the European project "Network for Observation of Volcanic and Atmospheric Change", in March 2008. This study presents the first dataset of SO2 plume fluxes recorded for a closed volcanic system. Between 2008 and 2010, the SO2 fluxes recorded showed average values of 12 t.d—1 during the normal sulfataric activity of Vulcano Island, with one exceptional event of strong degassing that occurred between September and December, 2009, when the SO2 emissions reached up to 100 t.d—1.

    Rapid differentiation in a sill-like magma reservoir: a case study from the campi flegrei caldera (2012)
    Nature Publishing Group
    Details
    Publication Date: 2017-04-04
    Description: In recent decades, geophysical investigations have detected wide magma reservoirs beneath quiescent calderas. However, the discovery of partially melted horizons inside the crust is not sufficient to put constraints on capability of reservoirs to supply cataclysmic eruptions, which strictly depends on the chemical-physical properties of magmas (composition, viscosity, gas content etc.), and thus on their differentiation histories. In this study, by using geochemical, isotopic and textural records of rocks erupted from the high-risk Campi Flegrei caldera, we show that the alkaline magmas have evolved toward a critical state of explosive behaviour over a time span shorter than the repose time of most volcanic systems and that these magmas have risen rapidly toward the surface. Moreover, similar results on the depth and timescale of magma storage were previously obtained for the neighbouring Somma-Vesuvius volcano. This consistency suggests that there might be a unique long-lived magma pool beneath the whole Neapolitan area.

    Site effects at the Campi Flegrei,preliminary results (2011)
    Istituto Nazionale di Geofisica e Vulcanologia
    Details
    Publication Date: 2017-04-04
    Description: The Campi Flegrei caldera is a complex structure with a high population density, located west of the city of Naples. In addition of being an active volcano it is characterized by a high seismic hazard due to both Appennines regional earthquakes and to local earthquakes occurring during the bradyseismic crises. These unrest phenomena are characterized by slow ground vertical movements, particularly active in the central part of the caldera, and by a high number of low-magnitude earthquakes. In this context, the determination of the site transfer functions of the area has a strong relevance for the Civil Defense aimed to determine the hazard of the area. We have calculated the site transfer function with different techniques (H/V and Generalized Inversion technique) and have collected data on the local geology with the aim of correlating the site transfer functions with lithology and topography. This analysis has been performed on three areas: the Astroni crater, the Camaldoli hill and the Agnano plain. A future development will be to extend this analysis to the whole Campi Flegrei area.

    Description: The individuation of areas that are more likely to be affected by new events in volcanic regions is of fundamental relevance for the mitigation of the possible consequences, both in terms of loss of human life and material properties. Here, we describe a methodology for defining flexible high-detail lava-hazard maps and a technique for the validation of the results obtained. The methodology relies on: (i) an accurate analysis of the past behavior of the volcano; (ii) a new version of the SCIARA model for lava-flow simulation (based on the macroscopic cellular automata paradigm); and (iii) high-performance parallel computing for increasing computational efficiency. The new release of the SCIARA model introduces a Bingham-like rheology as part of the minimization algorithm of the differences for the determination of outflows from a generic cell, and an improved approach to lava cooling. The method is here applied to Mount Etna, the most active volcano in Europe, and applications to landuse planning and hazard mitigation are presented.

    Structural analysis of the eruptive fissures at Mount Etna (Italy) (2011)
    Istituto Nazionale di Geofisica e Vulcanologia
    Details
    Publication Date: 2020-02-24
    Description: Mount Etna produces frequent eruptions from its summit craters and from fissures on its flanks. The flank fissures trend approximately radially to the summit, and are mainly concentrated in three rift zones that are located on the NE, S and W flanks. Many flank eruptions result from lateral magma transfer from the central conduit into fractures intersecting the flanks, although some eruptions are fed through newly formed conduits that are not directly linked to the central conduit. We analyzed the structural features of eruptions from 1900 to the present, one of the most active periods in the documented eruptive history of Etna, which comprised 35 summit and 33 flank events. Except for a small eruption on the W flank in 1974, all of the flank eruptions in this interval occurred on or near the NE and S rifts. Eruptions in the NE sector were generally shorter, but their fissure systems developed more rapidly and were longer than those in the S sector. In contrast, summit eruptions had longer mean durations, but generally lower effusion rates (excluding paroxysmal events characterized by very high effusion rates that lasted only a few hours). This database was examined considering the main parameters (frequency and strike) of the eruptive fissures that were active over the last ~2 ka. The distribution in time and space of summit and flank eruptions appears to be closely linked to the dynamics of the unstable E to S flank sector of Etna, which is undergoing periodic displacements induced by subvolcanic magma accumulation and gravitational pull. In this framework, magma accumulation below Etna exerts pressure against the unbuttressed E and S flanks, which have moved away from the rest of the volcano. This has caused an extension to the detachment zones, and has facilitated magma transfer from the central conduit into the flanks.

    Surface roughness of pyroclastic deposits at Mt. Etna by 3D laser scanning (2008)
    Istituto Nazionale di Geofisica e Vulcanologia
    Details
    Publication Date: 2019-11-04
    Description: The terrestrial 3D Laser Scanning technique has been applied to analyse the surface roughness of pyroclastic deposits on volcanic surfaces at Mt. Etna. This technique allowed the construction of high accuracy digital elevation models of small surfaces, about 1 m across. Sampled surfaces differ for percentage of coverage and for grain size of the pyroclastic deposits. The change in grain size distribution for the pyroclastic unconsolidated deposits affects the surface roughness. The roughness of the site where the finest pyroclastic deposits occur is mainly governed by large scale wavelength morphology (Hurst exponent H = 0.77 for lengths larger than 16 mm). The other sampled surfaces have self-affine characters with low (0.15) to intermediate (0.35 - 0.38) Hurst exponents for lengths higher than 10 – 22 mm. Here we show results of the analysis of the surface roughness of the pyroclastic deposits emplaced during the 2001 and 2002-2003 eruptions at Mt. Etna. Grain size and thickness of pyroclastic deposits mainly control the overall roughness of such as volcanic surface.

    High resolution magnetic anomaly map of Tenerife, Canary Islands (2007)
    Istituto Nazionale di Geofisica e Vulcanologia
    Details
    Publication Date: 2019-11-04
    Description: This study presents magnetic anomaly data from a new high-resolution, low-altitude helicopter-borne magnetic survey recently collected on and offshore Tenerife in the Canary Archipelago. The Italian Istituto Nazionale di Geofisica e Vulcanologia (INGV) in collaboration with the Museo Nacional de Ciencias Naturales of the CSIC of Spain conducted the survey in 2006. The data for Tenerife and surrounding marine areas were processed into digital total intensity magnetic anomalies for geomagnetic epoch 2006.4. Relative to previously available higher altitude magnetic survey data, the new survey mapped higher resolution anomalies with significantly improved spatial details, especially over the Las Cañadas caldera and Teide-Pico Viejo complex in the central part of the island. A good correlation is evident between known structural geology and the magnetic anomalies, where the new shorter wavelength anomalies facilitate more detailed and comprehensive geologic interpretations.
