Abstract
Abstract. Since 2002 the OGS (Istituto Nazionale di Oceanografia e di Geofisica Sperimentale) in Udine (Italy), the Zentralanstalt für Meteorologie und Geodynamik (ZAMG) in Vienna (Austria), and the Agencija Republike Slovenije za Okolje (ARSO) in Ljubljana (Slovenia) are collecting, analysing, archiving and exchanging seismic data in real time. Up to now the data exchange between the seismic data centres relied on internet: this however was not an ideal condition for civil protection purposes, since internet reliability is poor. For this reason, in 2012 the Protezione Civile della Provincia Autonoma di Bolzano in Bolzano (Italy) joined OGS, ZAMG and ARSO in the Interreg IV Italia-Austria project "SeismoSAT" (Progetto SeismoSAT, 2014) aimed in connecting the seismic data centres in real time via satellite. As already presented in the past, the general technical schema of the project has been outlined, data bandwidths and monthly volumes required have been quantified, the common satellite provider has been selected and the hardware has been purchased and installed. Right before the end of its financial period, the SeismoSAT project proved to be successful guaranteeing data connection stability between the involved data centres during an internet outage.
Highlights
The area at the border between Slovenia, Austria and NorthEast Italy is seismically very active and was struck by many destructive earthquakes in the past
The single seismic networks cannot determine precisely and efficiently enough earthquakes occurring at the borders: since 2002 OGS, Zentralanstalt für Meteorologie und Geodynamik (ZAMG) and Agencija Republike Slovenije za Okolje (ARSO) decided to use the same software suite Antelope (Bragato et al, 2010) as the main tool for collecting, analysing, archiving and exchanging seismic data in real time, initially in the framework of the EU Interreg IIIa Italia-Austria project “Trans-national seismological networks in the South-Eastern Alps” (Bragato et al, 2004)
For many years the data exchange between the seismic data centres relied on internet: this is not an ideal condition for civil protection purposes, since the reliability of standard internet connections is poor
Summary
The area at the border between Slovenia, Austria and NorthEast Italy is seismically very active and was struck by many destructive earthquakes in the past. The single seismic networks cannot determine precisely and efficiently enough earthquakes occurring at the borders: since 2002 OGS, ZAMG and ARSO decided to use the same software suite Antelope (Bragato et al, 2010) as the main tool for collecting, analysing, archiving and exchanging seismic data in real time, initially in the framework of the EU Interreg IIIa Italia-Austria project “Trans-national seismological networks in the South-Eastern Alps” (Bragato et al, 2004). For many years the data exchange between the seismic data centres relied on internet: this is not an ideal condition for civil protection purposes, since the reliability of standard internet connections is poor. Apart from the problem of antenna dislocation by strong earthquake, if provided with reliable power supply can provide more robust data connections. The SeismoSAT project makes use of satellite technology as back up for the primary internet data link between data centres.
