Abstract

Since 2002, OGS (Istituto Nazionale di Oceanografia e di Geofisica Sperimentale) in Italy, the Agencija Republike Slovenije za Okolje (ARSO) in Slovenia, and the Zentralanstalt für Meteorologie und Geodynamik (ZAMG) in Austria are exchanging seismic data in real time. The data exchange is very effective for seismic events at the borders between Italy, Slovenia and Austria, where the poor coverage of individual national seismic networks precluded a precise earthquake location. In 2014, OGS, ARSO and ZAMG seismic networks participated in the creation of the Central and Eastern European Earthquake Research Network (CE3RN; http://www.CE3RN.eu/; Bragato et al., 2014). In order to extend CE3R Network monitoring towards earthquake early warning applications, at the end of 2013 OGS, ARSO and ZAMG teamed with the RISSC-Lab group at the Naples University Federico II in Italy. The collaboration focuses on testing the platform PRESTo (PRobabilistic and Evolutionary early warning SysTem) developed by RISSC-Lab on CE3RN data. PRESTo is a stand-alone software that processes real-time data streams from a seismic network to promptly provide probabilistic and evolutionary location and magnitude estimates of detected earthquakes while they are occurring, as well as shaking prediction at the regional scale (Satriano et al., 2011). Since the beginning of 2014 PRESTo is running at CE3RN, originally collecting and analyzing in real-time data streams from 20 stations (Picozzi et al., 2015). At the beginning of 2015 PRESTo@CE3RN has been upgraded to add real-time data streams from broad band seismometers to the already configured accelerometers, thus more than doubling the total number of stations to the actual 43 (VEL@PRESTo@CE3RN). This required accurate testing to define the best configuration of the system: we will illustrate here results in system performances.
