Abstract:In this paper, we first collect crustal vertical velocity data from leveling network and cross-fault monitoring since 1970s, crustal horizontal velocity from present GPS measuring, the historical earthquake catalogue, and geological maps in Liupanshan and its adjacent areas. Second, we analyze the features of crust movement in the vertical direction and its implication for tectonic activity. The preliminary results indicate that: 1) The features of long-term vertical crust movement in Liupanshan, including the rising in Liupanshan, west Qinling, Helanshan and the sinking in basins, means that the crustal vertical movements are inherited. 2) Considering the GPS horizontal velocity, the crust is squeezing in areas where it is rising. 3) The GPS horizontal velocity in the west of Liupanshan fault is greater than that in the east, implying that the fault of Liupanshan is blocked and the level of accumulated strain is high. These results together indicate a high risk of future strong earthquakes.
