摘要：
The co seismic and post seismic deformation velocities of M s 8.1 Kunlunshan earthquake on Nov. 14, 2001 were calculated from the results of 1991-2001 GPS data and 4 repeated GPS surveys after the event. The result indicates the maximum co seismic and post seismic changes are 1.9 m and 0.08 m respectively. On the basis of the result of post seismic velocity, we used an elastic dislocation model to inverse the crustal deformation characteristics of eastern Kunlun active fault. The result shows that the domain motion of eastern Kunlun fault is left lateral and strike slip. The trend of eastward motion for the southern block of Kunlun fault implies redistribution and reaccumulation of energy after the earthquake. It is possible that the seismicity will migrate to eastern region in the future according to the trend that strong earthquakes along Kunlun fault extended from west to east during the last several decades.
