    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.

    Static chamber methane flux measurements in volcanic/geothermal areas: preliminary data from Sousaki and Nisyros (Greece) (2010)
    Copernicus
    Details
    Publication Date: 2017-04-04
    Description: Methane plays an important role in the Earth’s atmospheric chemistry and radiative balance being the second most important greenhouse gas after carbon dioxide. Methane is released to the atmosphere by a wide number of sources, both natural and anthropogenic, with the latter being twice as large as the former (IPCC, 2007). It has recently been established that significant amounts of geological methane, produced within the Earth’s crust, are currently released naturally into the atmosphere (Etiope, 2004). Active or recent volcanic/geothermal areas represent one of these sources of geological methane. But due to the fact that methane flux measurements are laboratory intensive, very few data have been collected until now and the contribution of this source has been generally indirectly estimated (Etiope et al., 2007). The Greek territory is geodynamically very active and has many volcanic and geothermal areas. Here we report on methane flux measurements made at two volcanic/geothermal systems along the South Aegean volcanic arc: Sousaki and Nisyros. The former is an extinct volcanic area of Plio-Pleistocene age hosting nowadays a low enthalpy geothermal field. The latter is a currently quiescent active volcanic system with strong fumarolic activity due to the presence of a high enthalpy geothermal system. Both systems have gas manifestations that emit significant amounts of hydrothermal methane and display important diffuse carbon dioxide emissions from the soils. New data on methane isotopic composition and higher hydrocarbon contents point to an abiogenic origin of the hydrothermal methane in the studied systems. Measured methane flux values range from –48 to 29,000 (38 sites) and from –20 to 1100 mg/mˆ2/d (35 sites) at Sousaki and Nisyros respectively. At Sousaki measurement sites covered almost all the degassing area and the diffuse methane output can be estimated in about 20 t/a from a surface of about 10,000 mˆ2. At Nisyros measurements covered the Stephanos and Kaminakia areas, which represent only a part of the entire degassing area. The two areas show very different methane degassing pattern with latter showing much higher flux values. Methane output can be estimated in about 0.25 t/a from an area of about 30,000 mˆ2 at Stephanos and about 1 t/a from an area of about 20,000 mˆ2 at Kaminakia. The total output from the entire geothermal system of Nisyros probably should not exceed 2 t/a.

    Environmental impact of Mt. Etna’s degassing: volcanogenic trace elements bioaccumulation in two endemic plant species (Senecio aethnensis and Rumex aethnensis) (2010)
    Copernicus
    Details
    Publication Date: 2017-04-04
    Description: A biomonitoring survey, above tree line level, using two endemic species (Senecio aethnensis and Rumex aethnensis) was performed on Mt. Etna, in order to evaluate the dispersion and the impact of volcanic atmospheric emissions. Samples of leaves were collected in summer 2008 from 30 sites in the upper part of the volcano (1500- 3000 m a.s.l). Acid digestion of samples was carried out with a microwave oven, and 44 elements were analyzed by using plasma spectrometry (ICP-MS and ICP-OES). The highest concentrations of all investigated elements were found in the samples collected closest to the degassing craters, and in the downwind sector, confirming that the eastern flank of Mt. Etna is the most impacted by volcanic emissions. Leaves collected along two radial transects from the active vents on the eastern flank, highlight that the levels of metals decrease one or two orders of magnitude with increasing distance from the source. This variability is higher for volatile elements (As, Bi, Cd, Cs, Pb, Sb, Tl) than for more refractory elements (Al, Ba, Sc, Si, Sr, Th, U). The two different species of plants do not show significant differences in the bioaccumulation of most of the analyzed elements, except for lanthanides, which are systematically enriched in Rumex leaves. The high concentrations of many toxic elements in the leaves allow us to consider these plants as highly tolerant species to the volcanic emissions, and suitable for biomonitoring researches in the Mt. Etna area.

    Atmospheric impact of volcanic volatiles: trace elements in snow and bulk deposition samples at Mount Etna (Italy) (2008)
    Copernicus
    Details
    Publication Date: 2017-04-04
    Description: Volcanoes represent an important natural source of several trace elements to the atmosphere. For some species (e.g., As, Cd, Pb and Se) they may be the main natural source and thereby strongly influencing geochemical cycles from the local to the global scale. Mount Etna is one of the most actively degassing volcanoes in the world, and it is considered to be, on the long-term average, the major atmospheric point source of many environmental harmful compounds. Their emission occurs either through continuous passive degassing from open-conduit activity or through sporadic paroxysmal eruptive activity, in the form of gases, aerosols or particulate. To estimate the environmental impact of magma-derived trace metals and their depositions processes, rainwater and snow samples were collected at Mount Etna area. Five bulk collectors have been deployed at various altitudes on the upper flanks around the summit craters of the volcano; samples were collected every two week for a period of one year and analyzed for the main chemical-physical parameters (electric conductivity and pH) and for major and trace elements concentrations. Chemical analysis of rainwater clearly shows that the volcanic contribution is always prevailing in the sampling site closest to the summit crater (about 1.5 km). In the distal sites (5.5-10 km from the summit) and downwind of the summit craters, the volcanic contribution is also detectable but often overwhelmed by anthropogenic or other natural (seawater spray, geogenic dust) contributions. Volcanic contribution may derive from both dry and wet deposition of gases and aerosols from the volcanic plume, but sometimes also from leaching of freshly emitted volcanic ashes. In fact, in our background site (7.5 km in the upwind direction) volcanic contribution has been detected only following an ash deposition event. About 30 samples of fresh snow were collected in the upper part of the volcano, during the winters 2006 and 2007 to estimate deposition processes at high altitude during cold periods. Some of the samples were collected immediately after a major explosive event from the summit craters to understand the interaction between snow and fresh erupted ash. Sulphur, Chlorine and Fluorine, are the major elements that prevailingly characterize the volcanic contribution in atmospheric precipitation on Mount Etna, but high concentrations of many trace elements are also detected in the studied samples. In particular, bulk deposition samples display high concentration of Al, Fe, Ti, Cu, As, Rb, Pb, Tl, Cd, Cr, U and Ag, in the site most exposed to the volcanic emissions: median concentration values are about two orders of magnitude higher than those measured in our background site. Also in the snow samples the volcanic signature is clearly detectable and decreases with distance from the summit craters. Some of the analysed elements display very high enrichment values with respect to the average crust and, in the closest site to the summit craters, also deposition values higher than those measured in polluted urban or industrial sites.

    The tropospheric processing of acidic gases and hydrogen sulphide in volcanic gas plumes as inferred from field and model investigations (2007)
    Copernicus
    Details
    Publication Date: 2017-04-04
    Description: Improving the constraints on the atmospheric fate and depletion rates of acidic compounds persistently emitted by non-erupting (quiescent) volcanoes is important for quantitatively predicting the environmental impact of volcanic gas plumes. Here, we present new experimental data coupled with modelling studies to investigate the chemical processing of acidic volcanogenic species during tropospheric dispersion. Diffusive tube samplers were deployed at Mount Etna, a very active open-conduit basaltic volcano in eastern Sicily, and Vulcano Island, a closed-conduit quiescent volcano in the Aeolian Islands (northern Sicily). Sulphur dioxide (SO2), hydrogen sulphide (H2S), hydrogen chloride (HCl) and hydrogen fluoride (HF) concentrations in the volcanic plumes (typically several minutes to a few hours old) were repeatedly determined at distances from the summit vents ranging from 0.1 to ~10 km, and under different environmental conditions. At both volcanoes, acidic gas concentrations were found to decrease exponentially with distance from the summit vents (e.g., SO2 decreases from ~10,000 μg/m3 at 0.1 km from Etna’s vents down to ~7 _μg/m3 at ~10km distance), reflecting the atmospheric dilution of the plume within the acid gas-free background troposphere. Conversely, SO2/HCl, SO2/HF, and SO2/H2S ratios in the plume showed no systematic changes with plume aging, and fit source compositions within analytical error. Assuming that SO2 losses by reaction are small during short-range atmospheric transport within quiescent (ash-free) volcanic plumes, our observations suggest that, for these short transport distances, atmospheric reactions for H2S and halogens are also negligible. The one-dimensional model MISTRA was used to simulate quantitatively the evolution of halogen and sulphur compounds in the plume of Mt. Etna. Model predictions support the hypothesis of minor HCl chemical processing during plume transport, at least in cloud-free conditions. Larger variations in the modelled SO2/HCl ratios were predicted under cloudy conditions, due to heterogeneous chlorine cycling in the aerosol phase. The modelled evolution of the SO2/H2S ratios is found to be substantially dependent on whether or not the interactions of H2S with halogens are included in the model. In the former case, H2S is assumed to be oxidized in the atmosphere mainly by OH, which results in minor chemical loss for H2S during plume aging and produces a fair match between modelled and measured SO2/H2S ratios. In the latter case, fast oxidation of H2S by Cl leads to H2S chemical lifetimes in the early plume of a few seconds, and thus SO2 to H2S ratios that increase sharply during plume transport. This disagreement between modelled and observed plume compositions suggests that more in-detail kinetic investigations are required for a proper evaluation of H2S chemical processing in volcanic plumes.

    Use of Forward Looking InfraRed thermal cameras at active volcanoes (2015)
    Istituto Nazionale di Geofisica e Vulcanologia
    Details
    Publication Date: 2017-04-04
    Description: Nowadays, thermal imaging has become a common remote sensing tool for monitoring active volcanoes. The study of temperature variations within openconduit systems, at eruptive fissures, active vents, domes, lava lakes, lava fields and other volcanic features has proven fundamental to better understand volcanic system behaviour over the short and long terms (Harris and Stevenson, 1997; Oppenheimer and Yirgu, 2002; Calvari et al., 2004; Wadge et al., 2006). At INGV Catania Section, thermal imaging has been applied at Mt Etna, Stromboli, Vulcano and Panarea since 2001. The instruments used are thermal cameras manufactured by FLIR (Forward Looking InfraRed) and consist in uncooled bolometers that are sensitive within 7.5 and 13 μ wavelengths. Thermal cameras are based on the capability to detect radiation emitted by bodies according to Planck’s Law. In particular, the camera we used is a FLIR thermal camera A 40 M Ethernet with a focal plane array uncooled bolometer (320 x 240 pixels), and a spectral range between 7.5 and 13 micrometers (Figure 1.). It has a standard optics 24° with spatial resolution (IFOV, instantaneous field of view) of 1.3 mrad, a horizontal view of 24° and a vertical view of 18°. This camera has also been equipped with optional filter to measure temperature values up to 1500°C with the possibility of setting up different temperature ranges. The thermal camera can record and transfer in real time via wi-fi radiometric frames in JPG format of the observed eruptive activity according to some environmental parameters, such as external temperature, air humidity and emissivity and allows the vision of volcanic activity both day and night.Temperature range varies between 0 e 500° C and the emissivity value ε = 1. To correct the temperature of all pixels from the atmospheric attenuation effects, we considered atmospheric parameters, such as air temperature and air humidity, in addition to the introduction of the path length (400 m) in the camera software. In fact, the radiations detected by the FLIR thermal cameras, that work in the spectral band between 7.5 e 13 μm, are affected by the absorption factor from the water spectrum, which is predominant in this band; particularly at La Fossa crater where the water content in the fumaroles is higher than the other gas species. Because of the necessity to correct the radiometric data from the atmospheric factors in real-time, we installed a meteorological station able to interface with the camera to provide atmospheric parameters for the auto-calibration.

    Seismic activity and thermal regime of low temperature fumaroles at Mt. Vesuvius in 2004-2011: distinguishing among seismic, volcanic and hydrological signals (2013)
    Istituto Nazionale di Geofisica e Vulcanologia
    Details
    Publication Date: 2017-04-04
    Description: Seismological, soil temperature and hydrological data from Mt. Vesuvius are collected to characterize the present-day activity of the volcanic/hydrothermal system and to detect possible unrest-related phenomena. We present patterns of seismicity and soil temperature in the crater area during the period February 2004-December 2011. The temporal distribution of number and depth of Volcano-Tectonic earthquakes and the energy release are considered. Hourly data of soil temperature have been acquired since January 2004 in different locations along the rim and within the crater. The observed changes of temperature are studied to establish a temporal-based correlation with the volcanic activity and/or with external forcing, as variations of the regional and local stress field acting on the volcano or meteorological phenomena. The comparison between seismic activity and temperature data highlights significant variations possibly related to changes in fluid circulation in the hydrothermal system of the volcano. The common continuous observations start just before a very shallow earthquake occurred in August 2005, which was preceded by a thermal anomaly. This coincidence has been interpreted as related to fluid-driven rock fracturing, as observed in other volcanoes. For the successive temporal patterns, the seismicity rate and energy release are characterized by slight variations accompanied by changes in temperature. This evidence of reactivity of the fumarole thermal field to seismic strain can be used to discriminate between tectonic and volcanic signals at Mt. Vesuvius.

    The impact of volcanic emissions on Etna’s snow cover (2011)
    Digilabs Pub., Bari, Italy
    Details
    Publication Date: 2017-04-04
    Description: Volcanoes are one of the major natural sources of several trace elements to the atmosphere: They contribute to atmospheric pollution by increasing the amount of reactive and greenhouse gases and aerosols. In particular, Mt. Etna is considered to be, on long-term average, the major global atmospheric point source of many environmental harmful compounds. Their emission occurs either through continuous passive degassing from open-conduit activity or through sporadic paroxysmal eruptive activity, in the form of gases, aerosols or particulate. For several months during the year (generally December-May), the summit of Mt. Etna is under a thick blanket of snow. This huge reservoir of frozen water, interacting with the volcanic plume, accumulates a great quantity of volcanogenic elements during the winter. Samples of snow were collected at different distances from summit craters along an 8 km radial transects, in the 2006 and 2007 winters. Each snow sample was analyzed for 37 elements in the laboratory using IC, ICP-OES and ICP-MS techniques. The impact of volcanic emissions is clearly detectable considering the opposite trends of pH and TDS (total dissolved solid) measured in snow samples with increasing distance from their “source”. The pH values range from 1.7 on the rim of the summit craters up to 7.6 at a distance of about 8 km, and TDS ranges from diluted samples (few mg/l) at distal sites, up to extremely concentrated samples (500 - 3500 mg/l) close to the emission vents. The acidity in precipitation around the volcano depends mainly on the concentrations of volcanogenic acid forming ions (SO2, HCl and HF), as well as on concentrations of mainly geogenic alkaline species, which may eventually neutralize the acidity. Regarding metals concentrations, there are orders of magnitude of difference between the different sites with decreasing values from the crater’s rim up to the farthest sites (5-8 km from craters). In particular three groups of elements were extremely enriched (many orders of magnitude higher) at the summit craters with respect to the distal samples: Halogens (Br, Cl, F, I) and S ascribable to volcanic gas contribution; Al, Fe and Ti deriving from magmatic silicate particulate; and elements such as Se, Cu, As, Bi, Cd, Tl, Pb and Hg which are highly mobile in the high temperature volcanic environment.

    Sulfur gas monitoring in volcanic/geothermal areas with passive samplers: human health implications (2011)
    Digilabs Pub., Bari, Italy
    Details
    Publication Date: 2017-04-04
    Description: Volcanic and geothermal areas are one of the major natural sources of sulphur gases to the atmosphere. Hydrogen sulphide (H2S) is a toxic gas mainly associated to geothermal systems while sulphur dioxide (SO2) is released in huge quantities from volcanoes characterized by open conduit activity. Apart from being one of the most impressive geodynamic expressions, volcanoes are also an important tourist attraction. During the summer season the number of tourists visiting the crateric areas each day is on average many tens at Stromboli, hundreds at Vulcano, Santorini and Nisyros and thousands at Etna. Touristic exploitation of active volcanic areas cannot exempt from warranting a reasonable security to the visiting persons. But while many risks in these areas have been since long time considered, gas hazard, a very subtle risk, is often disregarded. The atmospheric concentrations and dispersion pattern of naturally emitted SO2 were measured at three volcanoes of southern Italy (Etna, Vulcano and Stromboli) while that of H2S at four volcanic/geothermal areas of Greece (Sousaki, Milos, Santorini and Nisyros). Measurements were made with a network of passive samplers positioned at about 1.5 m above the ground, which gave time-integrated values for periods from few days to 1 month. Samplers were placed in zones of the volcanoes with high tourist frequentation. Measured concentrations and dispersion pattern depend on the strength of the source (craters, fumaroles), meteorological conditions and geomorphology of the area. At Etna, Vulcano, Stromboli and Nisyros measured concentrations reach values that are absolutely dangerous to people affected by bronchial asthma or lung diseases. But considering that these are average values over periods from few days up to one month, concentrations could have reached much higher peak values dangerous also to healthy people. The present study evidences a peculiar volcanic risk connected to the touristic exploitation of volcanic areas. Such risk is particularly enhanced at Etna where elderly and not perfectly healthy people can easily reach, with cableway and off-road vehicles, areas with dangerous SO2 concentrations.

    Chemical and mineralogical characterization of Etnean volcanic emissions using active biomonitoring technique (moss-bags) (2011)
    Digilabs Pub., Bari, Italy
    Details
    Publication Date: 2017-04-04
    Description: Biomonitoring may be defined as the use of organisms and biomaterials (biomonitors) to obtain informations on certain characteristics of a particular medium (atmosphere, hydrosphere etc.). In particular, mosses accumulate large amounts of trace metals, making them good bioaccumulators to estimate atmospheric pollution. The moss-bags technique, introduced in the early 1970’, has become very popular. Such active biomonitoring technique is particularly useful in highly polluted areas and has been extensively used in industrial and/or urban areas to examine deposition patterns and to recognize point sources of pollution. The main objective of this study, which represents the first application of the moss-bags technique in an active volcanic area, was to test its efficacy in such environment. Complementary objectives were: to determine the different behaviour and the areal dispersion of volcanogenic elements emitted from Mt. Etna; to characterize the morphology and mineralogy of particles transported in the plume-system, basing on microscopy investigation. A mixture of Sphagnum species was picked in a clean area, treated in laboratory (rinsed, dried and packed) and exposed in field for 1 month. Sites were chosen considering the prevailing wind at Mt. Etna’s summit. Milled samples were analyses for major and trace elements concentrations, after microwave digestion (HNO3 + H2O2), by ICP-MS and ICP-OES techniques. Morphology and mineralogy of volcanic particulate were investigated by using a SEM with EDS. Analyses clearly showed the efficacy of the moss-bags technique also in this peculiar environment. Several elements were strongly enriched in the mosses exposed to the volcanic emissions. The highest enrichment was measured close to the summit crater, but evidences of metals bioaccumulation were also found in down wind sites, at several km from the volcanic source. The accumulation factor (exposed/unexposed moss) allowed us to distinguish a group of elements (Tl, Bi, Se, Cu, As, Cd, S), which are highly mobile in the high temperature volcanic environment. Also alkali metals showed a significant increase in their concentrations, probably because of their affinity for the halide species carried by the volcanic plume. Microscopic observations evidenced sulphate and halide crystals on particles trapped by the mosses. Mosses exposed at sites directly fumigated by the volcanic plume showed crystal growth also directly on the moss surface.

    Description: In this paper are shown the results obtained from Geometric High Precision Levelling survey performed at Ischia Island in June 2010. The measures have been carried out on the whole network of the island further expanded by increasing of the benchmarks and the establishment of new lines. The compensated height for each benchmark (Bm) are referred to Bm 1 located at Ischia harbour, were compared to those obtained in previous Levelling survey of 2003. The results show significant ground subsidence of different entities affecting various areas of the island. In addition, a further comparison with the measurements performed in 1987 confirms the existence of such differential movements characterised by subsidence velocity constant over time. At last, we found a good agreement between levelling and GPS velocities, calculated in time span 1997-2003.

    Defining high-detail hazard maps by a cellular automata approach: application to Mount Etna (Italy) (2011)
    Istituto Nazionale di Geofisica e Vulcanologia
    Details
    Publication Date: 2017-04-04
    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.

    Automatic analysis of seismic data by using Neural Networks: applications to Italian volcanoes (2013)
    Istituto Nazionale di Geofisica e Vulcanologia
    Details
    Publication Date: 2017-04-04
    Description: The availability of the new computing techniques allows to perform advanced analysis in near real time, improving the seismological monitoring systems, which can extract more significant information from the raw data in a really short time. However, the correct identification of the events remains a critical aspect for the reliability of near real time automatic analysis. We approach this problem by using Neural Networks (NN) for discriminating among the seismic signals recorded in the Neapolitan volcanic area (Vesuvius, Phlegraean Fields). The proposed neural techniques have been also applied to other sets of seismic data recorded in Stromboli volcano. The obtained results are very encouraging, giving 100% of correct classification for some transient signals recorded at Vesuvius and allowing the clustering of the large dataset of VLP events recorded at Stromboli volcano.

    Studio di fattibilità per il monitoraggio delle deformazioni del fondo marino tramite GPS su una meda elastica (Golfo di Pozzuoli – Campi Flegrei) (2013)
    Istituto Nazionale di Geofisica e Vulcanologia
    Details
    Publication Date: 2017-04-04
    Description: The continuous measurement of ground deformations is an important contribution to the monitoring of volcanic areas. When the volcano is totally or partially submerged, the traditional geodetic methods cannot be applied and the measures of seafloor deformation are extremely difficult and expensive. This paper describes the installation of a continuous GPS station on an elastic beacon. The measurements were conducted in the Campi Flegrei Caldera (Gulf of Pozzuoli, Naples), whose vertical displacements are related to the bradyseismic phenomenon. Experimental observations show that it’s possible to monitor vertical displacement of seafloor with a resolution of a few centimeters, also taking into account for measurement errors (due to weather and sea conditions acting on the elastic beacon). This non expensive technique is relevant at Campi Flegrei area, because it extends the ground deformation monitoring at sea, contributing to a better modeling of the deformation field.

    The seismic monitoring network of Mt. Vesuvius (2015)
    Istituto Nazionale di Geofisica e Vulcanologia
    Details
    Publication Date: 2017-04-04
    Description: Mt. Vesuvius (southern Italy) is one of the most hazardous volcanoes in the world. Its activity is currently characterized by moderate seismicity, with hypocenters located beneath the crater zone with depth rarely exceeding 5 km and magnitudes generally less than 3. The current configu- ration of the seismic monitoring network of Mt. Vesuvius consists of 18 seismic stations and 7 infrasound microphones. During the period 2006- 2010 a seismic array with 48 channels was also operative. The station distribution provides appropriate coverage of the area around the volcanic edifice. The current development of the network and its geometry, under conditions of low seismic noise, allows locating seismic events with M〈1. Remote instruments continuously transmit data to the main acquisition center in Naples. Data transmission is realized using different technological solutions based on UHF, Wi-Fi radio links, and TCP/IP client-server applications. Data are collected in the monitoring center of the Osservatorio Vesuviano (Italian National Institute of Geophysics and Volcanology, Naples section), which is equipped with systems for displaying and analyzing signals, using both real-time automatic and manual procedures. 24-hour surveillance allows to immediately communicate any significant anomaly to the Civil Protection authorities.

    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.

    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.

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

    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.
