Since 2003 an agreement between the National Civil Defence (DPC) and the Regional Civil Defence (FVG-PC) has been signed in order to co-ordinate and integrate on the Friuli Venezia Giulia territory the National Accelerometric Network (RAN) and the Friuli Venezia Giulia Accelerometric Network (RAF). This co-operation will lead to the installation of new RAN accelerometric stations in the area and, in particular, will allow to automatically send RAN and RAF data to the DPC headquarters in Rome and to DST, through the FVG-PC data center.

An automatic procedure has been developed by DST to extract in real-time the ground motion parameters (PGA, PGV, PSA03, PSA10, PSA30, Arias and Housner intensities) and to exchange these data with other partners of the Project INGV-DPC S3.

Abstract

Since 2003 an agreement between the National Civil Defence (DPC) and the Regional Civil Defence (FVG-PC) has been signed in order to co-ordinate and integrate on the Friuli Venezia Giulia territory the National Accelerometric Network (RAN) and the Friuli Venezia Giulia Accelerometric Network (RAF). This co-operation will lead to the installation of new RAN accelerometric stations in the area and, in particular, will allow to automatically send RAN and RAF data to the DPC headquarters in Rome and to DST, through the FVG-PC data center. As FVG-PC consultant for the strong motion data, the DST collaborates to the sites selection and to the management of the new RAN stations. DST has recently performed detailed noise measurements in order to give a local geological classification of the recording sites. The RAF-RAN integrated network is configured to record accelerations at several important sites in the seismic area of Friuli Venezia Giulia and near its borders with Slovenia and Austria. The network geometry is built up taking into account also other seismological agencies and networks operating in Friuli Venezia Giulia (OGS) as well as in Austria (ZAMG) and Slovenia (ARSO). The data recorded in real-time, or quasi real-time, by the network, are collected and exchanged through the datacenters by the Antelope software. Antelope also analyzes and stores the collected waveforms in a database containing the signals recorded by this network and by the integrated transfrontier seismic network of the Southeastern Alps. An automatic procedure has been developed by DST to extract in real-time the ground motion parameters (PGA, PGV, PSA03, PSA10, PSA30, Arias and Housner intensities) and to exchange these data with other partners of the Project INGV-DPC S3. The ground motion parameters are used also to generate regional real time ShakeMaps, to compute regional weak motion GMPEs and possible ground-shaking scenarios. The collected waveforms are also used to study the physics of the seismic source, to estimate site effects and to perform microzonation analyses.
