Abstract:: In this paper,the original observation data of 100 points of total geomagnetic field at the junction in eastern-ward of Sichuan and Yunnan are obtained in April,2014.The data is calculated through eliminating the changing magnetic field and stripping off the main magnetic field,and the magnetic field model data of lithosphere is received.Then the GMS3.0 software is used to analyze the model data,and the shallow and deep anomalies of the lithospheric magnetic field are generated,respectively.Combined the seismic sequence characteristics and geological data of the Ludian M6.5 earthquake,it shows that:the Lianfeng fault and north section of the Xiaojiang fault's cut a depth of 15 km and above,while the Zhaotong-Ludian fault cut a depth of less than 15km.In addition,the spatial distribution of the Ludian afterchocks is along NW,and considering the aftershocks depth,It shows that the Baogunao-Xiaohe fault cut a depth of about 12km.
