LONG Sisheng,CHEN Ying (Seismological Bureau of Sichuan Province,Chengdu 610041,China)  
Seven earthquakes with magnitude about 4 occurred on AnningheZemuhe faults and in the near region from 2 January 2000 to 31 August 2002.The tectonic stress field and dislocation direction of the fracture surface of the focal mechanism solutions present a shallow strata slipping,where the seismic fault names are Miangning,Yuexi,Butuo,Puge,Qiaojia.AnningheZemuhe and Lianshan faults are the earthquakeoccurring faults.The Wolf projection method on lower plane with Pwave first motion symbols is used for seven focal mechanism solutions.
