198 GNGTS 2017 S essione 1.3 greatest amount of losses in case of future effusive eruptions at Etna. Finally, we quantified the lava flow impact of two past main effusive eruptions of Etna: the 1669, which is the biggest and destructive flank eruption to have occurred on Etna in historical time, and the 1981, lasting only 6 days, but characterized by an intense eruptive dynamics. All elements at stake were combined with the 1669 and 1981 lava flow fields to assess the social damage and economic loss.

The historical seismic activity of the Ischia Island is recognized since the XIII century (e.g., Isola d’Ischia 1275, Mw 4.01 ± 0.5, Io 8-9; CPTI15, https://emidius.mi.ingv.it/ASMI/# ) and caused serious damage, thousands of casualties, and often landslides and surface breaks.
