Abstract

On 24th August 2016 the first earthquake (Mw 6.2) of a long-lasting sequence struck Central Italy. The 24th August mainshock was in the surroundings of Amatrice, Central Italy, where about 300 people died. Most of the buildings were damaged and immediately after the earthquake Italian National Civil Protection (DPC) started coordinating the emergency and post-emergency activities. The latter included geological and geotechnical investigations for seismic microzonation carried out by the Centre for Seismic Microzonation (CMS) and the creation of a dedicated task force for rubbles management in the town of Amatrice. The present study presents preliminary results of the spatial correlation between the distribution of building damages generated by the 24th August earthquake, obtained by means of the Copernicus Emergency Management System (EMS) services, and the results of the seismic microzonation study of the village. We observed a spatial correlation between damages of buildings and seismic ground motion amplification, quantitatively estimated through an amplification factor (FHa). In particular, we observed an increasing trend of higher damaged buildings when FHa grows.
