SIMULATION OF DEFORMATION AND GRAVITY FIELD OF WENCHUAN Ms8.0 EARTHQUAKE
汶川地震形变场和重力场模拟分析

On the elastic dislocation theory in the homogeniously continuous,isotropic and infinite half-space,we calculated the coseismic deformation field and gravity field caused by the Wenchuan Ms8.0 earthquake and analyzed the influence of the fault parameters and crustal media structure on the deformation and gravity field.It shows that the calculated results with multi-subfaults model are nearly agree with the observed ones and compared to the results with mean dislocation model the accuracy improves to 40%.The...
