This interferogram shows ground motion associated with the 26 December 2003 earthquake at Bam in Iran. The interferogram was created by combining an Envisat Advanced Synthetic Aperture Radar (ASAR) Wide Swath Mode (WSM) image with an Image Mode (IM) image. Typically IM is the sole ASAR mode exploited for interferography; making use of WSM in this way has the potential to broaden Envisat's InSAR coverage in future. Processed by Politecnico of Milano.
