Abstract In this paper, current vertical mobility of Shanxi is studied, according to observational data, calculation of vertical deformation variables and the vertical deformation rate of leveling across the Shanxi rift zone section. Since 2006, the vertical deformation of Shanxi with the northeast of the Yanhuai and Weixian basins show rising tilting activity. Further, north of the Yangyuan and the Datong basins present decreasing activity, the Jinzhong basin fluctuates and the Linfen basin shows rising activity. However, the tipping point of Shanxi activity appears in 2013. The Weixian basin has decreased by a large margin. The Datong, Daixian-Dingxiang, Jinzhong and Linfen basins have risen to varying degrees.
