14. Three-dimensional magnetotelluric modeling of Vulcano island (Aeolian archipelago, Italy) and its implications for recent volcanic unrest

Author

Di Giuseppe, Maria Giulia, Isaia, Roberto, and Troiano, Antonio

Abstract

Raising the alert level concerning Vulcano has led to increased monitoring activities concerning the island. One of the leading research topics to enhance the knowledge of this volcanic system is the characterization of the volcano-tectonic structures of the island and their relation with the geothermal system.We present a 3D resistivity imaging obtained by the Magnetotelluric (MT) method, highlighting the structures of the La Fossa crater down to 2 km depth b.s.l.The geometry of the resistivity anomalies elucidates the different volcano-tectonic lineaments that characterize the volcanological evolution of Vulcano island and provides valuable indications for understanding the interaction between lithostratigraphic setting, fluid circulation, and the current dynamics recorded on the island.The most significant structure identified by the MT survey is a resistive anomaly located at La Fossa crater, which continuously deepens to the maximum depths detected and represents a conduit-type structure along which there is a preferential ascent of magmatic fluids.Furthermore, the resistivity anomalies are mainly aligned in the N-S direction and contain the outgassing structures of the N-NE sector of the crater. They probably represent the island sector where, in addition to the ascent of magmas from recent activity, the most significant quantities of fluids from the deep accumulate/channeling. The model also shows that the higher resistivity bodies emerging at the surface mainly correspond to volcanic buildings, craters, conduits, and/or eruptive fissures.The deep structures imaged by the MT model become very significant in light of the interpretation of the possible unrest dynamics at Vulcano., The 28th IUGG General Assembly (IUGG2023) (Berlin 2023)

15. The deep structure of the Campi Flegrei caldera by magnetotelluric survey

Abstract

Electromagnetic imaging can proficiently detect deep structures in volcanic environments. A magnetotelluric (MT) survey has been performed in the Campi Flegrei volcanic environment, crossing the caldera through the main, recent volcano-tectonic structures and intersecting the most active sector of the Solfatra-Agnano zone. The electromagnetic reconstruction of the volcano’s internal structure points out the configuration of the plumbing system and the main structures for the ascent of magma and magmatic fluids, at least below a large continental portion of the caldera. The preliminary picture of the electrical resistivity distribution with depth suggests that the CF caldera plumbing system appears to be formed by distinct branches with a shallower geothermal system well developed below the Solfatara-Agnano area fed by a deeper source. The primary fault system, acting as a preferential pathway for magmatic fluids, is also identified. The resistivity model allows (i) to constrain the main electromagnetic features of the caldera and (ii) to delineate significant clues about its structural setting.This new picture represents a relevant contribution furnished by MT observations for hazard assessment at Campi Flegrei and can enhance the modeling of the driving mechanisms of the ongoing unrest., The 28th IUGG General Assembly (IUGG2023) (Berlin 2023)

Abstract

Nowadays, modeling of tephra fallout hazard is coupled with probabilistic analysis that takes into account the natural variability of the volcanic phenomena in terms of eruption probability, eruption sizes, vent position, and meteorological conditions. In this framework, we present a prototypal methodology to carry out the long-term tephra fallout hazard assessment in southern Italy from the active Neapolitan volcanoes: Somma–Vesuvius, Campi Flegrei, and Ischia. The FALL3D model (v.8.0) has been used to run thousands of numerical simulations (1500 per eruption size class), considering the ECMWF ERA5 meteorological dataset over the last 30 years. The output in terms of tephra ground load has been processed within a new workflow for large-scale, high-resolution volcanic hazard assessment, relying on a Bayesian procedure, in order to provide the mean annual frequency with which the tephra load at the ground exceeds given critical thresholds at a target site within a 50-year exposure time. Our results are expressed in terms of absolute mean hazard maps considering different levels of aggregation, from the impact of each volcanic source and eruption size class to the quantification of the total hazard. This work provides, for the first time, a multi-volcano probabilistic hazard assessment posed by tephra fallout, comparable with those used for seismic phenomena and other natural disasters. This methodology can be applied to any other volcanic areas or over different exposure times, allowing researchers to account for the eruptive history of the target volcanoes that, when available, could include the occurrence of less frequent large eruptions, representing critical elements for risk evaluations.
