Since the radar images in addition to signal intensity measurement, carry the phase information, thus we can use phase information with InSAR method in studying earthquakes. Whereas most geodetic methods need to measure crust displacements repeatedly, InSAR in addition to covering all of the earth surface, doesn’t need to repeat measurements. In this study, with InSAR surface displacements, the targets have been invented form Bam earthquake of Iran.
With this method the magnitude of the Bam earthquake and its moment are 6/4 and respectively.
In this study, we use 3 images of Envisat satellite for producing interferogram. Images are processed in Linux with Doris software. Finally, counting the fringes of interferogram, we can calculate the displacement and magnitude of Bam earthquake, and compare these results with other studies.
