Abstract:: Using the cross-fault deformation data from Dushanzi station,this paper makes a preliminary analysis on movement rate,movement character and regional tectonic stress field of Dushanzi-Anjihai fault,and compares with the results of focal mechanism solutions for verification.The result shows that:(1)The nowadays movement of Dushanzi-Anjihai fault is characterized by right-lateral thrust motion,the average annual change of vertical movement is 0.106mm,the average annual change of horizontal movement is 0.189mm,and the average annual change of right-lateral slipping movement is -0.883mm.(2)The direction of maximum principal stress is between 339.35° and 346.78°,the average is 344.23°.(3)Dushanzi deformation station recorded preliminary anomaly and co-seismic variation before the WuSu M_S5.1 earthquake。
