摘要

The Silakhor (Lorestan, Iran) earthquake (Ms = 6.1) occurred on 31 March 2006, at 01:17:01 Greenwich Mean Time (GMT),shaking the Silakhor district in west Iran. In the macroseimal area, about 50% of buildings totally collapsed, and the others were severely damaged. The event occurred on the Dorud fault,a reverse high-angle fault with a strike-slip component, but it did not have a surface rupture. The macro-seismic analyses and analysis of the recorded accelerogram in Chalanchulan (0.52 g vertical and 0.43 g horizontal with TS – TP value of about 1.2 seconds) show that the epicenter is very close to Chalanchulan town. Although many of the masonry buildings totally collapsed in the epicentral area, engineered structures constructed according to the seismic code of Iran showed very good structural behavior without any significant damage. Finally, the earthquake intensity is determined as VIII on the MSK scale at the epicenter and strongly decreases with distance from the fault.
