Microseismicity surveys of the fault-systems of S. E. Spain

Abstract

Three microseismicity surveys were carried out in 1982, 1984 and 1985 in south-east Spain. The main survey was in 1984 with 24 seismic recording stations installed during 41 days. A total of 103 earthquakes were recorded with magnitudes between 0.5 and 3.9. Epicenters can be associated to faults in the area, which are shown to be seismically active. Larger activity is concentrated at the southern part of the area. Joint fault plane solutions show mecanism of fault with vertical motion of normal and reverse character.Part of this work has been supported by the DGICT, project PB-86-0431-C05 and the Comité Conjunto Hispano-Norteamericano para la cooperación cientifica y tecnologíca project CCA-8309/009.Peer reviewe
