Combining the data recorded by the mobile observation instruments and digital observation station，we relocated the 343 earthquakes occurred in Qianguo，Jilin Province between October 31～December 10,2013 with double-difference location algorithm，and finally obtained 336 relocated earthquakes. Our result shows that the advantage distribution direction is NW paralleled to the northern segment of Chaganpao-Daozijing fault zone. The relocated earthquake sequence are more concentrated on obvious strip around the fault，while most of them occur at the depth of 6～14km. This shows that the seismogenic layer in this region is in the mid-upper crust contacting significantly with the regional underground media. The earthquake location and depths about the MS5.5 and MS5.8 earthquake sequences have been improved with the same way. It shows significant differences on advantage direction，advantage depths and rupture length of the two relocated earthquake sequences. The seismotectonics of the earthquake sequence is in NNW for the Chaganpao-Daozijing fault through the focal mechanism solution and relocated profile map.
