This paper processed data from the ALOS/PALSAR satellite of Japan and analysed the coseismic deformation characteristics of the Yushu earthquake 2010 using the Differential Interferometric Synthetic Aperture Radar (D-InSAR) technology. The investigation indicates that the deformation characteristics of this earthquake are consistent with that of seismogenic fault. The maximum slant range displacement is about -61.4 cm, and the overall horizontal displacement along the fault direction reaches -129.3 cm. The location of the maximum displacement is at 96°51′26″E, 33°03′11″N, which is very close to the location of macro-epicenter derived from field investigation. The surface rupture zone is about 60 km long. The maximum relative displacement across the fault is 182.3 cm. The displacements of the southwest wall of the fault are obviously more than that of the northeast wall. This phenomenon may be caused by aftershocks mostly occurred in the southwest wall.
