Description:
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.
