Abstract
This paper deals with seismotectonic and seismicity of the Silakhor region that shows high seismic activity in western Iran Silakhor is a vast plain with several villages and cities of Dorud and Borujerd and a small town of Chalanchulan that were destroyed and/or damaged many times by large earthquakes This paper addresses the historical and instrumental earthquakes and their causative faults seismotectonic provinces and seismotectonic zones of the region Available seismic data were normalized by means of time normalization technique that resulted in the magnitudefrequency relation for the Silakhor area and estimation of the return period of earthquakes with different magnitudes Some active faults in this region include the Dorud fault the main Zagros thrust the Galehhatam fault the Sahneh fault and others Among them the Dorud fault is an earthquake fault and is the cause for most of the large and intermediate earthquakes in the region The return period of large earthquakes with magnitudes greater than 70 Ms is very low however the occurrence of destructive earthquakes is greater in the region than in the neighboring provinces The study proves the high seismicity of this zone and it is required to develop an accurate national plan for future building and reinforcement of the existing buildings in this region
