Abstract :
This paper firstly presents the Multi-LOS DInSAR measurement result of the coseismic deformation field caused by the Gaize Ms6.9 mainshock and Ms6.0 aftershock in Tibet, China, and then obtain the 3D deformation field based on the 3D resolving mode. The characteristic analysis of coseismic deformation field shows the rupture of mainshock is majority normal, left-lateral striking with a little rotation; and the aftershock is typical normal rupture nature. The mainshock and aftershock had induced the east and west rupture(maybe buried) successively, and produced the east and west two subsiding centers.
