Abstract


Following the Ml 5.9 earthquake that struck the Emilia area in northern Italy on May 20, 2012, at 02:03:53 UTC, and in co-operation with the personnel of the Municipality of Ferrara and the University of Ferrara, a team of seismologists of the Istituto Nazionale di Oceanografia e Geofisica Sperimentale (OGS; National Institute of Oceanography and Experimental Geophysics) deployed a temporary seismographic network. This consisted of eight portable seismological stations, to record the local earthquakes that occurred during the seismic sequence. The OGS intervention was integrated into the broader action of the emergency response to the earthquake sequence, which was promoted by the National Department of Civil Protection and the Istituto Nazionale di Geofisica e Vulcanologia (INGV; National Institute of Geophysics and Volcanology) [Moretti et al. 2012, this volume]. The aim of the OGS intervention was on the one hand to extend the seismic monitoring area towards the East, to include Ferrara and its surroundings, to be ready in case of migration of the seismicity in that direction, and on the other hand to evaluate the seismic response at the instrumented sites. Some days later, another team of researchers coordinated by the University of Potenza carried out some investigations at a number of sites, and in particular at three of the sites instrumented by the OGS temporary network.
