The Collato permanent network aims at monitoring the gas storage activity performed by Edison Stoccaggio s.p.a. in the underground natural reservoir named "Collalto stoccaggio", located in the Veneto Region near the town of Susegana (Treviso). The network is registered with FDSN with code EV. Since this network aims at recording both the natural seismicity and the induced seismicity, it has been designed with features of high sensitivity, high dynamics and wide frequency range.
This network is operating since January 1st, 2012. Continuous waveforms can be freely downloaded through this site.
The network consists of 10 sites, specifically built-up for the purpose (Fig. 1). However, the monitoring system acquires some other stations of the North-Eastern Italy Broad-Band and Friuli and Veneto Short-Period permanent networks managed by OGS (network codes NI and FV, respectively). All the EV sites host the seismometric sensors within boreholes, at dephts ranging from 5m to 155m.
Each station is equipped with a digital acquisition unit, a seismometric sensor deployed at depth, optionally (i.e at 5 sites) an accelerometric sensor deployed at surface, an autonomous energy supply (photovoltaic panels, in most cases) and electric batteries, a telecommunication system and Global Positioning System (GPS) antenna for precise time synchronization.
The seismological instrumentation is:
