Simulation of co-seismic gravity change and deformation of Wenchuan Ms8.0 earthquake

co 地震的严肃变化和排水量由 Wenchuan Ms8 引起了的表面。分别地， 0 地震由地球物理， CEA 和 USGS 的研究所根据一半空间脱臼理论和二差错模型 inversed 是计算的。结果显示出那 1 )脱臼由剧降组成滑倒并且权利侧面的罢工滑倒； 2 )co地震的严肃变化证明一个四象限的模式，哪个是极大地由垂直排水量的分发控制了，吗在特别近文件； 3 )严肃变化通常是不到 10 汦潯敤?楷桴？

Surface co-seismic gravity changes and displacements caused by the Wenchuan Ms8.0 earthquake are calculated on the basis of the half-space dislocation theory and two fault models inversed, respectively, by Institute of Geophysics, CEA and USGS. The results show that 1 ） the dislocation consists of dip slip and rightlateral strike slip ;2 ）the co-seismic gravity change shows a four-quadrant pattern ,which is greatly controlled by the distribution of the vertical displacements, especially in the near-filed ; 3 ） the gravity change is generally less than 10 × 10^-8 ms^-2 in the far-field,but as high as several 100 × 10^-8 ms^-2 in the near-filed. These results basically agree with observational results.
