Rapid response to the earthquake emergency of May 2012 in the Po Plain, northern Italy

Abstract

<p>Rapid-response seismic networks are an important element in the response to seismic crises. They temporarily improve the detection performance of permanent monitoring systems during seismic sequences. The improvement in earthquake detection and location capabilities can be important for decision makers to assess the current situation, and can provide invaluable data for scientific studies related to hazard, tectonics and earthquake physics. Aftershocks and the clustering of the locations of seismic events help to characterize the dimensions of the causative fault. Knowing the number, size and timing of the aftershocks or the clustering seismic events can help in the foreseeing of the characteristics of future seismic sequences in the same tectonic environment. Instrumental rapid response requires a high degree of preparedness. A mission in response to a magnitude (Ml) 6 event with a rupture length of a few tens of kilometers might involve the deployment within hours to days of 30-50 seismic stations in the middle of a disaster area of some hundreds of square kilometers, and the installation of an operational center to help in the logistics and communications. When an earthquake strikes in a populated area, which is almost always the case in Italy, driving the relevant seismic response is more difficult. […]</p><br />

SISMIKO: emergency network deployment and data sharing for the 2016 central Italy seismic sequence

“…The INGV was in contact with these two groups since the start of the seismic emergency when they had expressed interest in deploying a Broad Band network (BB) to supplement the INGV-SISMIKO network in region. Thus, as in the 1997-98 seismic sequence in Umbria [Amato et al 1998] and in 2009 in Abruzzo [Margheriti et al 2011], and in Emilia 2012 [Moretti et al 2012] we welcomed this international collaboration between European research institutes. This collaboration resulted in two weeks of fieldwork starting at the beginning of September, has led to the installation of an additional 25 BB seismic stations (Fig.…”

“…The station, equipped with a short period velocimeter and an accelerometer, transmitted data in real-time via satellite connection, it was deployed in the village Casale Bucci, close Amatrice, in the southern sector of the sequence. Similar to the Emilia emergency in 2012 [Moretti et al 2012;2013], there has been a continuous interaction with EMERSITO (Fig. 2, fuchsia hexagons) and with the mobile network group of the Italian Strong Motion Network (RAN-DPC, http://ran.protezionecivile.it/; Fig.…”

Joint Inversion of Geodetic and Strong Motion Data for the 2012, Mw 6.1–6.0, May 20th and May 29th, Northern Italy Earthquakes: Source Models and Seismotectonic Interpretation

“…We used strong motion data recorded by permanent stations of the national accelerometric network (https://rischi.protezionecivile.gov.it/en/seismic/activities/emergency-planning-and-damage-scenarios/ran-national-accelerometric-network) and of the INGV Italian seismic network and by local stations installed soon after the first mainshock (Moretti et al., 2012). We selected 8 and 14 strong motion stations for the May 20th and the May 29th mainshocks, respectively (black triangle, in Figures 2a and 2b).…”

“…In addition, we used for the first time strong motion stations installed by Istituto Nazionale di Geofisica e Vulcanologia (INGV) soon after the May 20th mainshock (Re.Mo. network; Moretti et al., 2012).…”

INGV strong-motion data web-portal: a focus on the Emilia seismic sequence of May-June 2012

“…Plain (northern Italy) from May 20 to June 12 (Figure 2, left panel). The data were recorded by all of the INGV permanent and temporary strong-motion stations that were installed in northern Italy, including from the RSN [Amato and Mele 2008], the RAIS (http://rais.mi.ingv.it/) [Augliera et al 2011] and the INGV temporary network [Moretti et al 2012, Bordoni et al 2012, with latitudes ≥43.5 ˚N. The locations and local magnitudes, M L , that are reported on the web site were provided by the CNT of INGV (http://cnt.rm.ingv.it/).…”
