Improving CTBTO monitoring capabilities: the Italian proposal for a CNF

The Centro di Ricerche Sismologiche (CRS, Seismological Research Center) in Udine (Italy) of the OGS (Istituto Nazionale di Oceanografia e di Geofisica Sperimentale), the Italian National Institute for Oceanography and Experimental Geophysics, after the M=6.4 earthquake occurred in 1976 in the Friuli-Venezia Giulia region, started to operate the Northeastern Italy Seismic Network: it currently consists of 18 very sensitive broad band and 20 simpler short period seismic stations, all telemetered to and acquired in real time at the OGS-CRS data center. OGS is formally part of the Central and Eastern European Earthquake Research Network CE3RN (http://www.CE3RN.eu/; Bragato et al., 2014). Real time data exchange agreements in place with CE3RN and other Italian and Swiss seismological institutes lead to a total number of about 100 seismic stations acquired in real time by the CRS, which makes the OGS the reference institute for seismic monitoring of Northeastern Italy (Bragato et al., 2011). To further support CTBTO activities (Pesaresi and Horn, 2004), OGS proposes with the support of the Italian CTBTO National Authority one of its stations of the Northeast Italy Seismic Network as a Cooperating National Facility (CNF) to the CTBTO. A description of the Cludinico (CLUD) station proposed as CNF, together with results of CTBTO monitoring improvements simulations will be here illustrated.
