Abstract The coseismic surface deformation information of Yushu earthquake on April 14,2010 is firstly extracted by using ALOS PALSAR and ENVISAT ASAR based on interferometry technique. Analysis of displacement fields shows that there were surface ruptures three times,at least, the deformation along the fault was much larger than that of the perpendicular, where the effect is in range of 10 km. Maximum displacement reaches 54 cm in line of sight, 180 cm in horizontal deriction. Deformation distributions and characteristics are very consistent with that of sinistral strike slip. The consistency is found between the two results from ALOS PALSAR and ENVISAT ASAR separately. In addition, the location of macroepicenter derived from InSAR very close to that from field investigation. It means that InSAR is a simple and quick means to locate macroepicenter of an earthquake.
