Abstract: Since 1970s about 110 fixed or / and mobile stations of cross fault leveling have been laid out to measure vertical deformation in North China. Considering the tectonic unit division, these stations can be divided into five groups: Shanxi zone, Tanlu zone, western Yinshan-Yanshan zone, eastern Yinshan-Yanshan zone, and Capital circle area. From all the data 80 items of measurements are analyzed to calculate the deformation rates associated with faults. The results show that the average rate of vertical deformation across faults is 0.335mm/a in North China. There are, however, large differences of fault motion rates between tectonic zones. The Shanxi graben zone has the largest fault deformation rate showing it is the most important block boundary of North China. The fault deformation rates of other tectonic zones are relatively low.
