Abstract:GPS observation comparing with the SKS fast-wave polarization through the crustmantle and seismic anisotropy of the crust was used in this paper to study the coupling relationship between the crustal movement and the mantle deformation. We found that the fast-wave polarization in the crust is always a few degrees above ten with the SKS fast-wave. This difference may show the decoupling of crustal movement and mantle deformation in the Shandong region. The characteristic of Shandong region is that the crust-mantle coupling is not simply crust-mantle decoupling,nor a strong coupling. There may be an uneven distribution caused by two kinds of coexistent modes or a gradual change of physical property between the two modes. The finding is consistent with the previous conclusions by the similar studies of North China.
