Abstract The Ms8.1 earthquake occured in the west to Kunlun mountain pass in 2001 created a fault of about 400 km. The epicenter region which is the most west part of the fault is selected as studied area. Using the Multitemporal European ERS2 SAR imagery and shuttlebased SRTM DEM data,the surficial displacements are estimated with twopass and threepass DINSAR methods respectively. The comparison between the two results shows that over fluctuating mountains twopass DINSAR with external DEM might obtain better results than threepass DINSAR method and the fault along the south side of Taiyang lake formed from the Ms8.1 earthquake is leftlateral.
