Source Parameters of The 26 April 2007 Bam Earthquake Obtained By The Near Field Accelerograms Data

On 26 December 2003 at 05:26LT (01:26GMT), a catastrophic earthquake Mw 6.6, seismic moment (6 – 9 ×10 Nm) struck the city of Bam in the Kerman province of southeast Iran. The intense shaking in the city caused the complete collapse of nearly every building in the central parts of the city including many of the newer buildings, killing about 40000 people officially. The city lies to the east of the Nyband – Gowk – Sarvestan fault system and on which several powerful earthquakes have occurred over the past 23 years [Berberian et al., 1984; Berberian and Qorashi, 1994; Berberian et al., 2001]. There are no recorded historical earthquakes at Bam. Most of the citadel of Arg-e-Bam, one of world heritage sites inscribed by UNESCO, which was constructed by mud brick about 2000 years ago was destroyed in this earthquake.
