Abstract:
The Bam earthquake of December 26, 2003 (Mw6.5) occurred at 01:56:56 (GMT, 05:26:26 local time) around the city of Bam in the southeast of Iran (Figure-1). The number of victims was declared officially to be more than 30000. The surface fissures are found on and around the Bam quaternary fault scarp, between Bam and Baravat. The focal depth is estimated to be about 8km. The macroseismic intensity was greater than IX (EMS98) in Bam and VIII in Baravat. The near fault motion in Bam caused a vertical directivity and greater long period motions on vertical and fault normal accelerograms. A fast attenuation is observed in this event especially on the fault normal direction.
