Preliminary analysis of the accelerometric recordings of the August 24th , 2016 M W 6.0 Amatrice earthquake

On 24 August 2016, at 1.36:32 GMT, a MW 6.0 earthquake with epicenter located below the village of Accumoli, struck a wide area among the boundaries of Lazio, Abruzzo, Umbria and Marche regions (Central Italy): the main event caused the collapse of several buildings and about 300 fatalities, mainly in the towns of Amatrice, Arquata del Tronto and Accumoli. The main event was recorded by about 350 sensors, be- longing to the Italian Accelerometric Network (Rete Accelerometrica Nazionale, RAN) operated by the Department of Civil Protection (DPC), the Italian Seismic Network (Rete Sismica Nazionale, RSN) man- aged by the Istituto Nazionale di Geofisica e Vulcanologia (INGV), and to other local networks. All the corrected data are available at the Engineering Strong Motion Database (esm.mi.ingv.it). This paper re- ports the preliminary results of the analysis of the strong-motion recordings.
