In volcanic areas, accurate localization of earthquakes requires detailed velocity and,
possibly, attenuation models, taking into account wide lithological variability and high
geothermal gradients. Ischia island (Campania region, Italy) is a seismically-active volcano
recently affected by a Mw 3.9 event (Casamicciola, August 21, 2017, 1 km depth). Due to the
lack of a specific velocity model, the earthquakes occurred on the island were localized
using the one developed for the nearby Campi Flegrei caldera. The aim of this work is the …
