Collalto Seismic Network (RSC)
OGS manages the Collalto Seismic Network (RSC) for seismic monitoring in the natural gas storage concession area called Collalto Stoccaggio (TV), managed by Edison Stoccaggio S.p.A. Given the medium-high seismic hazard of the area, the network was designed to detect both local micro-seismicity and natural seismicity in the area surrounding the reservoir.
The network (operational since 2012) is the first public network built in Italy following ministerial requirements for seismic monitoring of gas storage activities, and consists of ten broadband seismometric stations and a permanent GNSS geodetic station. All seismometers are installed in the well, while accelerometers are installed on the surface.
Cornegliano Laudense Seismic Network (RSCL)
OGS also manages the Cornegliano Laudense Seismic Network (RSCL) which is part of the monitoring system installed to detect seismic events and soil deformation at the natural gas storage concession "Cornegliano Stoccaggio". The integrated monitoring system was set up on behalf of the owner of the gas storage concession in Cornegliano Laudense, Ital Gas Storage S.p.A.
The network has been operational since 01/01/2017 and consists of nine seismometric stations, all equipped with the same instrumentation, manufactured by Guralp Systems Ltd., consisting of: a Radian broadband digital velocimeter (in the well, at a depth of about 75 m), a Fortis broadband compact accelerometer (on the surface) and a Minimus 24-bit digitiser.
