A new System for Earthquake Detection and Source Parameters Determination in Italy

Abstract

A new agreement between the Italian Istituto Nazionale di Geofisica e Vulcanologia (INGV) and the Italian Civil Protection Agency drove (o inspired) a new effort towards the implemen- tation of a robust, reliable and efficient system for real time seismic monitoring of the Italian country and the surrounding regions. Earthworm has been configured as the automatic processing system to analyze the signals of the Italian National Seismic Network that counts today more than (??? 230 ???) stations equipped with broad-band, very-broad-band and short period instruments. Such realization required a fine tuning of several modules to account for the specificity of the Italian Case, where various earthquake scenarios appear few tens of kilometers apart such as shallow crustal seismicity in the Apennines, and deep and very deep earthquakes in the southern Tyr- rhenian sea. We will present and discuss the proposed schema and the results of the extensive test based on the optimal configuration in terms of accuracy and rapidness
