The 21 August 2017 Ischia (Italy) Earthquake Source Model Inferred From Seismological, GPS, and DInSAR Measurements
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.Published2193-22023T. Sorgente sismicaJCR Journa

Statistics of seismicity to investigate the Campi Flegrei caldera unrest
The knowledge of the dynamic of the Campi Flegrei calderic system is a primary goal to mitigate the volcanic risk in one of the most densely populated volcanic areas in the world. From 1950 to 1990 Campi Flegrei suffered three bradyseismic crises with a total uplift of 4.3 m. After 20 years of subsidence, the uplift started again in 2005 accompained by a low increment of the seismicity rate. In 2012 an increment in the seismic energy release and a variation in the gas composition of the fumaroles of Solfatara (in the central area of the caldera) were recorded. Since then, a slow and progressive increase in phenomena continued until today. We analyze the INGV - Osservatorio Vesuviano seismic catalogue of Campi Flegrei from 2000 to 2020 in order to look for any variation in the seismic parameters and compare them with geochemical monitored ones. A remarkable correlation between independent variables of earthquake cumulative number, CO/CO2 values and vertical ground deformation reveals a likely common origin. Moreover the correlation between all the variables here analysed enlightens that the same origin can cause the temporal behavior of all these variables. We interpret the seismological, geochemical and geodetic observable in terms of the injection of magmatic fluids into the hydrothermal system or its pressurization
