Abstract: Based on the recent vertical deformation data cross fault and max-shear strain field given by GPS data in middle Shanxi Province, the authors conducted simulation and interpolated strain value to the 8 unusual sites cross fault proposed in 2005 consultant conference. The Lintong-Changan fault shows obvious positive correlation, but Kouzhen-Guanshan fault and Huashanshanqian fault are negative correlation; the northern segment of Qishan-Mazhao fault is obvious positive correlation but middle and south segments are not. It is probably resulted from dynamical difference of these faults and different actual stress along different segments. Especially, the vertical movement of the eastern segment of Kouzhen-Guanshan fault and northern part of Qishan-Mazhao fault is strong, which should be pain more attention.

Key words: Vertical deformation, Horizontal strain, Correlation analysis, Middle region in Shanxi
