abstract
An intense earthquake occurred in western Iran, about 225 km west of Tehran at 7:28 local time, June 22, 2002. Though the moderate moment magnitude of 6.4(ERI, University of Tokyo) - 6.5 (USGS) calculated for this earthquake was not surprisingly large as contrasted with those historical major earthquakes in this country, 261 people were reportedly killed and 1,300 injured. We investigated the activated fault trace and observed the outcrop of suface rupture near the epicenter area of main shock from 27 July to 30. We recognized surface rupture associated with this earthquake extended for about 700m east of Abdarreh village. Amount of displacement upthrown to the south is less than 10cm. It's expected that faulting occurred several times along the same bedding fault related to the flexural-slip by the growth of fold.
