Coordinated by the Istituto Nazionale di Geofisica e Vulcanologia (INGV), which is responsible at national level for the volcanic monitoring, the project has as main objective to develop a pre-operative system based on EO data and ground measurements integration to support the volcanic risk monitoring of the Italian Civil Protection Department. The project philosophy is to implement specific modules which allow to process, store and visualize through Web GIS tools EO derived parameters considering three activity phases: 1) knowledge and prevention; 2) crisis; 3) post crisis. In order to combine effectively the EO data and the ground networks measurements the system will implement a multi-parametric analysis tool, which represents and unique tool to analyze contemporaneously a large data set of data in “near real time”. The SRV project will be tested his operational capabilities on three Italian Volcanoes: Etna,Vesuvio and Campi Flegrei.193 482 - PublicationOpen AccessDInSAR Analysis and Analytical Modeling of Mount Etna Displacements: The December 2018 Volcano‐Tectonic Crisis(2019)
; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ;; ; ; ; ; ; ; ; ; ; ; ; ; ;; ;We investigate the 24–27 December 2018 eruption of Mount Etna occurred from fissures located on the volcano eastern flank and accompanied by a seismic swarm, which was triggered by the magma intrusion and continued for weeks after the end of the eruption. Moreover, this swarm involved some of the shallow volcano‐tectonic structures located on the Mount Etna flanks and culminated on 26 December with the strongest event (ML 4.8), occurred along the Fiandaca Fault. In this work, we analyze seismological data and Sentinel‐1 Differential Interferometric Synthetic Aperture Radar (DInSAR) measurements, the latter inverted through analytical modeling. Our results suggest that a dike source intruded, promoting the opening of the eruptive fissures fed by a shallower dike. Moreover, our findings indicate that the activation of faults in different sectors of the volcano may be considered as a response to accommodate the deformations induced by the magma volumes injection.928 48 - PublicationOpen AccessVolcanic Risk Management: the Case of Mt.

Etna volcano is located in a very populated area of eastern Sicily (Italy). Its permanent degassing activity from summit craters and frequent eruptions impact significantly on town habitations and cultivated areas. In the latest years Etna has produced copious ash emission causing great losses to local economy and causing serious hazards to national and international air traffic over Mediterranean area and the often closure of Catania airport. In July 2006 eruptive vents opened on the East and South flanks of the summit craters showing irregular explosive and effusive activity lasting 6 months. This eruption represented the opportunity to perform the pre-operative test of FP6 Eurorisk-Preview (Prevention, Information and Early Warning) project aimed to develop tools for monitoring volcanoes. The test was performed during two temporal phases: the first one of early-warning was aimed to measure ground deformation and the second one during the crisis to survey volcanic ash produced during the explosions. The ground deformations were measured through the elaboration of SAR data. Beside the geophysical objectives, the test was also important to check data availability and efficiency of European Space Agency procedures. The pre-operative test has been peculiar to understand and quantify the delivering time of the final satellite products expected from the Volcanological Observatory in operative case. The analysis of July 2005 - July 2006 SAR data showed a pre-eruptive inflation trend in agreement with the ground network of GPS data. The magmatic source, that produced the September - October activity, has been located about 2.7 km below the summit craters. During the crisis phase characterized by paroxysmal activity, the Italian Civil Protection (DPC) in charge of airport closure in case of volcanic hazard, requested the satellite volcanic ash product retrieved from the NASA-MODIS data. An agreement between the industry Telespazio as direct broadcast of satellite data at Matera station and INGV was signed in order to elaborate the data in near-real time. The volcanic ash product provided information about: the presence of volcanic ash in the air; the affected area; the volcanic plume dispersal direction, dimensions and altitude and the volcanic ash loading. The satellite products and the observations report have been successively inserted in a web-interface. At the same time the observations report has been linked to the DPC dedicated Web-GIS interface that allows in a short time the availability of volcanic ash information to DPC in support to their decisions.297 5208 - PublicationOpen AccessThe 21 August 2017 Ischia (Italy) Earthquake Source Model Inferred From Seismological, GPS, and DInSAR Measurements(2018)
; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ;; ;; ;; ;; ;; ;; ;; ; ; ; ; ; ; ;; The causative source of the first damaging earthquake instrumentally recorded in the Island of Ischia, occurred on 21 August 2017, has been studied through a multiparametric geophysical approach. In order to investigate the source geometry and kinematics we exploit seismological, Global Positioning System, and Sentinel-1 and COSMO-SkyMed differential interferometric synthetic aperture radar coseismic measurements. Our results indicate that the retrieved solutions from the geodetic data modeling and the seismological data are plausible; in particular, the best fit solution consists of an E-W striking, south dipping normal fault, with its center located at a depth of 800 m. Moreover, the retrieved causative fault is consistent with the rheological stratification of the crust in this zone. This study allows us to improve the knowledge of the volcano-tectonic processes occurring on the Island, which is crucial for a better assessment of the seismic risk in the area.1199 104 - PublicationOpen AccessMultiple natural hazards at volcanic islands: a review for the Ischia volcano (Italy)(2019)
; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; Volcanic islands pose several major types of natural hazards, often interconnected and concentrated in relatively small areas. The quantification of these hazards must be framed from a multi-hazard perspective whilst building on existing single-hazard analyses. Ischia is a densely inhabited volcanic island with a long eruptive history lasting more than 150 ka (last in 1302 AD) characterized by the significant asymmetric resurgence of a caldera block. Here, we review the state-of-art of the natural hazards of Ischia, aiming at building a solid base for future holistic multihazard quantifications. We frame our analysis in three steps: i) review of geological, historical and current activity; ii) review of available hazard models and analyses; iii) development of an interpretative framework for the interdependent hazards. The results highlight that volcanic activity has been quite intense and many volcanorelated hazardous phenomena have affected the island including in very recent times, both for eruptive (phreatic or magmatic eruptions) and non-eruptive (earthquakes, landslides, and tsunamis) phenomena. The effects of some of them (e.g. tsunamis, tephra) are also relevant beyond the island territory. Quantitative hazard assessments are almost absent and should be developed in the future considering the evident interconnections between hazards.To this end, we propose a conceptual interpretative multi-hazard framework that highlights the fundamental role played by the resurgent block in controlling and connecting the different hazards, in terms of both spatial distribution of the sources and temporal clustering.1013 46
