Abstract
One heavy earthquake with MS8.0 occurred on May12, 2008 in Wenchuan County, Sichuan province. After the earthquake, the bed weather has made the optical satellite acquired data difficultly. Microwave can transmit through cloud and rain, sosyntheti caperture radar images has widely used in Wenchuan earthquake hazard monitoring and assessment.Usinghigh-resolutionSARimages, such as COMOS, Terra SAR, RADARSAT, the building and roads which has been damaged by earthquake wer monitored and the landslides, debris flow, landslide blocked lake were recognized. The result shows that high resolution SAR images are very important data source in natural hazard monitoring and assessment, especially in the cloudy and rainy weather.
