Research

The SeisRaM has a longstanding experience in the seismological filed for which carries out research activity, education/training, divulgation and consultation. The main activities are: seismic monitoring, identification of active fault systems, optimization of location algorithms, crustal tomography, definition of seismic source and ground motion parameters, calculation of ground motion scenarios, seismic monitoring of building, seismic monitoring of landslide, site characterization and response and seismic microzonation.

Seismic Monitoring

The SeisRaM group manages about 35 seismic stations in the Friuli Venezia Giulia and Veneto regions: 6 broadband stations owned by University of Trieste, 17 accelerometric stations of the RAF owned by University of Trieste and 14 accelerometric stations of the RAN owned by the Dipartimento di Protezione Civile. The RAF network is fully integrated with RAN network. The RAF is a founder of the Ce3RN network. The RAF is a research infrastructure of the EPOS Italy. The RAF participates to the AlpsArray project.

RAF - Friuli Venezia Giulia and Veneto Accelerometric Network

The first stations of the Friuli Venezia Giulia and Veneto (NE Italy) Accelerometric Network (RAF) were installed during 1993–1995 by the Department of Earth Sciences,University of Trieste (DST) (now Department of Mathematics and Geosciences (DMG)) in the framework of international scientific projects. Until 1999 the network was operated by DST in co-operation with ENEL-Ingegneria e Costruzioni. From the beginning the network has been equipped with digital, three-component instruments GMT time synchronized, mostly installed in small electricity transformer buildings. In November 1999 the collaboration between DST and ENEL ended due to the internal reorganization of the ENEL group. As a consequence, at the end of 1999, the configuration of the network changed. New more appropriate free-field sites were found near the original ones. RAF is today configured to record accelerations at several important sites in the seismic area of Friuli Venezia Giulia (FVG) and near its borders with Slovenia and Austria. Its geometry has been studied taking into account the locations of stations belonging to other seismological agencies and networks operating in the neighbouring countries and in Italy.The RAF stations allow real-time or near-real-time data transmission to the seismological datacenters and to the Friuli Venezia Giulia Direction of the Civil Defence (FVG-DPC) headquarters. As a consequence the accelerations recorded at each site are immediately available after the earthquake occurrence.
