In this study the Satellite Radar Interferometry (InSAR) was applied to investigate the crustal deformation caused by the Bam Earthquake (M/sub w/=6.5) that occurred in Iran on December 26, 2003. It was a multiple seismic event that destroyed the historical City of Bam and provoked great damages in the urban centers of the region. The Bam area in the south-eastern part of Iran is an active seismic zone and the Bam Fault System is comprised by three specific segments (north, east and SE of Bam). The three-pass interferometric technique was applied using ENVISAT ASAR scenes. According to the interferometric processing results subsidence has occurred in the area NE of Bam City, while dextral strike-slip displacement has taken place in the southern area of Bam. The last deformation could be attribute to a parallel hidden segment of the Bam Fault that is reaching the surface according to the shear displacement during the earthquake.
