“…The network geometry is dense in the area above the reservoir, where the station spacing is about 2-4 km, and gradually rarifies to merge harmoniously in the regional seismic networks operated by the OGS (Priolo et al, 2005;Bragato et al, 2011). The RSC is equipped with a number of stations that preserve the monitoring capability in case of temporary malfunctioning of some instruments or communications.…”

“…Much of the off-line processing, and in particular event detection, is performed by the BRTT Antelope system (http://www .brtt.com/; last accessed September 2014), which is the same system used by the Northeastern Italy Integrated Seismic Network (NEI), managed by the OGS (Priolo et al, 2005;Bragato et al, 2011). This part will be more broadly described in the following section.…”

“…The instrumental seismicity recorded by the OGS since 1977 (http:// rts.crs.inogs.it; last accessed September 2014) is moderate in the PS district, the biggest event having M D 4.0, and few events exceeding magnitude 3. It is worth mentioning that this area could have been affected by a deficit in detection capability due to the less dense station distribution in the Veneto, compared to the adjacent Friuli and Trentino regions (Priolo et al, 2005;Garbin and Priolo, 2013).…”

A full description of the characteristics of the monitoring is reported in Priolo et al (2005), and the list of events located using HYPO71 (Lee and Lahr, 1975) is public and available on the web site http://www.crs.inogs.it/bollettino/RSFVG/RSFVG.en.html. The magnitude adopted in this catalogue is the duration magnitude obtained using the Rebez and Renner (1991) formula.…”

The Region-Time-Length (RTL) algorithm has been applied to different instrumental catalogues to detect seismic quiescence before medium-to-large earthquakes in Italy in the last two decades. RTL performances are sensitive to the choice of spatial and temporal parameters. The method for automatic parameters selection developed by Chen and Wu has been applied to 12Italian earthquakes with magnitude greater than 5. The limits of the method in constructing maps of seismic quiescence before the earthquake are demonstrated, and a simple improvement is proposed.Then a new technique, namely RTL surv , is proposed for routine surveys of the Italian seismicity.

“…The current network geometry follows the criterion to monitor the Italian territory giving priority to urban areas. It is well integrated with about 161 local strong-motion stations and small networks operated by research institutes and universities (Priolo et al 2005;Weber et al 2007;Augliera et al 2009;Costa et al 2009). Today the RAN counts 422 stations and provides a dense station coverage for all high seismic hazard areas.…”

On April 6, 2009, the town of L'Aquila in the Abruzzo region (central Italy) was struck by a seismic event at 01:32 (UTC), of magnitude M W = 6.3. The mainshock was followed by a long period of intense seismic activity and within seven days after the mainshock there were seven events of magnitude M W ≥ 5 that occurred from April 6 to April 13. This long seismic sequence was characterized by a complex rupture mechanism that involved two major normal faults of the central Apennines: the Paganica and the Gorzano faults. The strong-motions of the mainshock were recorded by 64 stations of the Italian Strongmotion Network (RAN) operated by the National Civil Protection Department (DPC). Six stations of a local strong-motion array were working in NW L'Aquila suburb area. One of them, located at about 6 km from the Paganica fault surface tip-line, set up in trigger mode, recorded continuously for more than 20 min the mainshock and the aftershocks. Besides the mainshock, the RAN stations recorded in total 78 foreshocks and aftershocks of M L ≥ 3.5, during the period from January to December 2009. The corresponding waveforms provide the most extensive digital strong ground motion data set ever recorded in Italy. Moreover, the 48 three-component observations of events of magnitude M W ≥ 5, recorded at a distance less than 15 km from each of the major involved faults, provide a significant increasing of near-field records available for the Italian territory. Six days after the mainshock, the strongmotion dataset, referred to preliminary locations of the events with M 123 40 Bull Earthquake Eng (2011) 9:39-65 are described. In addition the role of the temporary network that represents an extension of the permanent Italian strong-motion network, supporting the emergency response by civil protection authorities and improving the network coverage has been evaluated.
