SummaryAssessment of the damage to urban areas after earthquakes and other natural disasters is important for both the rapid response to rescue survivors and for longer term planning and evaluation of the recovery process. It has been performed previously with optical imagery. We recently showed that InSAR correlation analysis of the Envisat data for the city of Bam, Iran after the devasting earthquake in December 2003 can be used to measure the areas damaged by the earthquake. By taking the difference between pre-event interferometric correlation and InSAR correlation spanning the event, the changes during the event can be effectively isolated. Three of the main limitations for the InSAR assessment that we found with Envisat will be avoided by the advanced high resolution of TerraSAR-X, the smaller orbit variation, and the much shorter repeat interval of its orbit.
