Lake Pertusillo reservoir induced seismicity catalog (Southern Italy)
- 1. Istituto Nazionale di Geofisica e Vulcanologia
Description
We present a detailed analysis of the small magnitude (ML<3) Reservoir Induced Seismicity associated with the Pertusillo water reservoir located in the high seismic hazard zone of Val d’Agri (Southern Italy).
We apply template-matching detection to a 13-month-long dense passive survey, obtaining a final high-precision double-difference catalog of 5,068 earthquakes (-0.7<ML<2.6, MC=0.2).
The original template dataset is composed of 408 hand-picked earthquakes, recorded during a 13-month-long (2005-2006) passive survey, at a dense network of 46 seismic stations (the average receiver spacing is 5 km) composed by: 22 temporary 3C continuously-recording stations of the temporary experiment described in Valoroso et al., [2009], plus 24 permanent INGV and ENI (the local oil company) stations, and accurately located in a 3D high-resolution VP and VP/VS velocity model [Improta et al., 2017].
