Abstract：Taking the Tianshan tectonic belt area as an example, we give the crustal deformation vertical movement rate vector maps, using precision leveling and GNSS, respectively. We analyze and discuss in depth the differences and their causes. Based on the principle of complementary advantages, we give the deformation image of the fusion of the two. Based on many years’ research experience using geodetic deformation data to predict strong earthquakes, we consider that the vertical deformation map obtained by this method has more important application value in the study of strong earthquake prediction.
