Abstract：The theoretical coseismic gravity changes in the height of satellite orbit and coseismic deformation results of SumatraAdaman and Wenchuan earthquakes are simulated and calculated by using satellite gravity models, dislocation theory and up continuation technique, the characteristics of deep structures of Longmenshan fault region geophysical condition for strong earthquake occurrence are revealed.
