Bam (Iran) earthquake (December 26th, 2003)
 
On Dec. 26, 2003 at 01:56:56 (GMT) a destructive earthquake (Mw6.5, Ms6.7, USGS) hit the city of Bam in Kerman province, SE Iran. Up to this moment, strong ground motions were recorded by 24 set of SSA-2 digital accelerographs (BHRC). The maximum peak ground acceleration as much as 988 gals was recorded at the Bam station (raw data, vertical component).
The epicenter of the earthquake has been located at 29.00N, 58.33E (NEIC) and 29.21 N, 58.40 E (IGTU). First indication of the hypocenter location was obtained from the nearest recorded accelerogram at Bam station, with a Ts-Tp of about 1 second, suggesting a focal distance of about 7km. Best double couple solution of the mainshock, as obtained from preliminary moment tensor solution of the event indicates a right-lateral strike-slip movement on a N-S trending fault rupture.
