The real-time earthquake monitoring system in Italy

Abstract

As regards the transmission vectors – one of the most critical points of a seismic network – we adopted a mixed strategy: half of the stations are connected through satellite links, and half through cable links. The use of satellite transmission presents several advantages: the link is very robust, the constraints for site selection are weak, and the cost is lower than telephone lines. As regards the terrestrial cable links, we use INGV digitizers (named GAIA), protected IP connections of the Italian Public Administration Network (RUPA): site selection is more delicate, and a compromise must be found between low environmental noise and availability of network infrastructures.
