Abstract

The Mw=6.5 Bam earthquake, taking place on 26th December 2003 in Iran, caused severe surface deformation. This paper described that it used the differential interferometric SAR (D-InSAR) technique and ENVISAT ASAR data to monitor the Bam co-seismic deformation fields. Firstly, it introduced the principle of D-InSAR and the method to select proper D-InSAR data pairs. Then we used ENVISAT ASAR data to carry out D-InSAR test in the Bam earthquake. We successfully got the Bam co-seismic deformation field. The shape and location of the fault caused by the Bam earthquake was also found in the coherence maps. The test proved that D-InSAR technique is a powerful tool to measure surface deformation and to study earthquake.
