dc.description.abstractThe most active seismic spot in the northwestern part of the Iberian Peninsula is located between Becerreá and Triacastela (Lugo). Since 1995 an apparent increase of the activity has taken place: several seismic events took place, which included twenty earthquakes of the magnitude > 4 and a main event of magnitude 5.3 (21 May 1997). Most recently, a permanent low-magnitude activity (5-10 events/month) is registered in this zone. Lack of suitable seismic information prevents any rigorous analysis of this activity and its origin. We undertook a detailed study of the local seismicity between 1999 and 2002, based on the deployment of a temporary seismic array (CASPI Project). The integration of the new seismic data and the geologic information has allowed to obtain an updated image of the seismicity of this zone and to identify the Becerreá fault like the main seismogenetic sourceen_US
