On August 21, 2017 at 20:57 (local time) an earthquake with Md = 4.0 (Lat. 40.74°, Long 13.90°, hypocentre's depth at about 2 km) hit the Ischia island heavily damaging the Casamicciola village and causing two fatalities (Azzaro et al., 2017). The island of Ischia (Southern Italy) is the emerged portion of a volcanic complex belonging to Campi Flegrei volcanic field, located Northwest of the Gulf of Naples inside of the Campanian volcanic province. Volcanic activity begun around 150.000 years ago and continued until 1302, with the last lava flow eruption of the Arso. A composite surveying team (EMERGEO INGV in collaboration with CNR/IAMC) activated immediately since August 22 in order to perform the first investigations of the coseismic effects at the surface. The Emergeo Working Group surveyed the epicentral area and surroundings, in the northern sector of the Ischia island, collecting about 50 observation points related to different geological coseismic effects.

Abstract
On August 21, 2017 at 20:57 (local time) an earthquake with Md = 4.0 (Lat. 40.74°, Long 13.90°, hypocentre's depth at about 2 km) hit the Ischia island heavily damaging the Casamicciola village and causing two fatalities (Azzaro et al., 2017). The island of Ischia (Southern Italy) is the emerged portion of a volcanic complex belonging to Campi Flegrei volcanic field, located Northwest of the Gulf of Naples inside of the Campanian volcanic province. Volcanic activity begun around 150.000 years ago and continued until 1302, with the last lava flow eruption of the Arso. A composite surveying team (EMERGEO INGV in collaboration with CNR/IAMC) activated immediately since August 22 in order to perform the first investigations of the coseismic effects at the surface. The Emergeo Working Group surveyed the epicentral area and surroundings, in the northern sector of the Ischia island, collecting about 50 observation points related to different geological coseismic effects.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
