In this paper,the characteristics of seismicity and tectonics of Shexian area are studied through geological and geomorphological survey,seismicity analysis and geochronology analysis,and the tectonic background for the occurrence of Shexian M_S6.0 earthquake are summarized as follows:①The epicenter of the M_S6.0 earthquake is located in the intersection area of large-scale seismic belt and seismic sub belt,and the seismicity is still high at present;②The conjugate faults in NE and NW directions are developed near the earthquake area,and there is a large-scale and highly active fault-Shexian fault,which controls the boundary of mountain basin;③The epicenter of the M_S6.0 earthquake is located on the edge of the isolated Shexian faulted basin area,and the basin mountain neotectonic movement is different in some aspects.
