Abstract It is founded that there are significant differences in the hypocentral parameters of the Kunlun Ms8.1 earthquake in some present corresponding studies. This work is based on the multirupture segment superposition model obtained by the conversion from the InSar data. According to the point dislocation theory, some focal parameters have been reasonably modified by means of the inversion technique of forward simulation in constraint of the GPS measurements,thus a new model of the Kunlun Mountain
Ms8.1 earthquake is obtained.As a result, the co-seismic horizontal deformation field, which is in better agreement with the GPS measurements and the field investigation results, has been deduced. Meanwhile, the coseismic vertical deformation and gravity changes are given.
