The 26 December 2003, Bam, Iran earthquake: surface displacement from Envisat ASAR interferometry

On 26 December 2003 a 6.5?Mw earthquake took place near the city of Bam, in south-eastern Iran. In order to detect the surface displacement field due to the Bam earthquake, we used satellite sensor images from the new European C-band Envisat Advanced Synthetic Aperture Radar (ASAR). The displacement pattern from InSAR (SAR Interferometry) is well defined. It evidences a north–south high fringe gradient stream located 4?km west of the Bam fault. This result represents an important contribution to knowledge of the rupture process of this event and can be useful for improving and revising the interpretations of geological, geodetic and seismological data.
