Abstract On the basis of analysis of the faultcrossing deformation observation data on Shanxi fault zone, this paper discussed the deformation characteristics of the zone. According to the longterm trend analysis, tensional deformation has been the main deformation of both the north and the south part of the Shanxi fault. On the middle part shearing is the main deformation. The time subsection results indicates that from 1989 to 2000, faulting inverse inheritance turning changes appeared in three stations:Xiadazhi, Daixian, Guangsheng temple,in the central part of Shanxi fault zone. In the same time, the absolute value of the fault’s vertical movement rate significantly reduced, which reflectes a locking condition of the fault activity in Xiadazhi, Daixian, Guangsheng temple area. In addition, the faultcrossing deformation observation data and GPS strain rate field results indicate that the Shanxi fault deformed mainly with a near NW tensional deformation. However, as the different observation dimension, the value between them are not be comparable.
