Abstract

On 16 August 2018 at 18:19:04 UTC an earthquake with magnitude ML 5.2 (MW 5.1) occurred in the Molise region. The earthquake was felt in a large area including many regions of Central and Southern Italy. The seismologists on duty in the 24H seismic monitoring room of the National Institute of Geophysics and Volcanology (INGV) located the event in the province of Campobasso, 4 km southeast of Montecilfone and at a preliminary depth of 9 km. The same area was affected two days before by a MW 4.6 event (August 14 at 23.48 Italian time1). Following the MW 5.1 event and the associated aftershock sequence, the SISMIKO Operational Group was activated [Moretti et al., 2012; 2016a; 2016b; Pondrelli et al., 2016] for the installation of temporary seismic stations to integrate the permanent stations of the National Seismic Network (RSN [Michelini et al., 2016; INGV Seismological Data Centre]) deployed in the region.
