We used the radar data from the satellite ENVISAT/ASAR of ESA and the differential interferometric synthetic aperture radar (D-InSAR) technology to derive the coseismic displacement field produced by the Yushu, Qinghai Province, China Ms 7.1 earthquake on 14 April 2010. Based on processing SAR data acquired before and after the event by the two-pass method, we obtained the interferometric fringe map...
The D-InSAR technology is used to aquired seven belts of coseismic surface deformation of Sichuan M8 earthquake of 12 May 2008 from the ALOS/PALSAR satellite data of Japan. The result covers Yinxiu, Dujiangyan, Wenchuan, Moxian, Beichuan, Pingwu and Qingchuan county, each 500 km in north-south and 70 km in east-west. The investigation indicates that the surface rupture zone caused by the earthquake...
