Bollettino Sismico Italiano 2008

Abstract

In this work we give information on the characteristics of the Italian National Seismic Network and on the seismicity and main seismic sequences in Italy during 2008. During that year the Italian National Seismic Network localized 6969 events in Italy and neighboring areas, with an apparent minimum magnitude of completeness ML of 2.1. The entire Italian Seismic Bulletin 2008 was obtained using signals from 279 stations belonging to the INGV Italian National Seismic Network and to other local and regional networks, all with real-time connection to the Centro Nazionale Terremoti in Rome. Some evidences confirm the presence of a certain percentage of events due to anthropic activity (explosions), erroneously interpreted as earthquakes of lowmagnitude.We identify 14 areas with the presence of explosions due to surfacemining activity, generating events with ML not exceeding 2.2.
