| 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 Multi-temporal European ERS-2 SAR imagery and shuttle-based SRTM DEM data,the surficial displacements are estimated with two-pass and three-pass DINSAR methods respectively.The comparison between the two results shows that over fluctuating mountains two-pass DINSAR with external DEM might obtain better results than three-pass DINSAR method and the fault along the south side of Taiyang lake formed from the Ms8.1 earthquake is left-lateral. |
