Considering the inhomogeneousness, stratified and spherical characteristic of earth structure, the co-seismic deformation difference among spherical earth layering model, spherical homogeneous model and half-space homogeneous model has been studied in this paper. The quantitative difference due to the influence by the crustal layering and earth curvature have also been calculated out and compared. The calculation results show that the surface co-seismic deformation difference is so large that exceeding the accuracy of high precise observation technology if not considering the actually earth structure when just taking the earth as half-space homogeneous medium. If one wants to use the high accurate observation data (such as GPS, VIBL, InSAR observations) to do the inversion research, the effect from the stratified crustal structure can not be ignored.
