Recent seismicity before the 24 August 2016 Mw 6.0 central Italy earthquake as recorded by the ReSIICO seismic network

Abstract

The seismicity of the last four years before the August 24 2016 01:36 UTC MW 6.0 earthquake that struck central Italy is presented with the aim to understand the preparatory phase of the event. In contrast with the 2009 L’Aquila earthquake that was preceded by a seismic sequence and the 2013-2015 Gubbio seismic swarm that, to date, is ended without any strong event, our preliminary results don’t show seismic sequences in the last months previous the mainshock of the August 24 2016 and a low similarity between seismicity clusters in the last four years and the foreshocks.
