Absolute Relocation of the Guangxi Jingxi M_S5.2 Earthquake Sequence

We systematically collect the data of the Guangxi Jingxi M_S5.2 earthquake sequence recorded by the fixed and mobile stations of the Guangxi Earthquake Networks Center, and use the hyp2000 method to absolutely relocate the Guangxi Jingxi M_S5.2 earthquake sequence, and compare the different crustal velocity structure models and initiation of search depth on locating results. The results show that it is ideal to use a comprehensive model with 2 km as the starting search depth. The sequence of the earthquake was spread in the NE direction, which was basically consistent with the NE-trending Xialei-Lingma fault near the epicenter. The depth of the earthquake sequence is mainly distributed in 4 ~ 8 km, the relocation depth of the M_S5.2 earthquake is about 3.5 km, and the relocation depth of the 4.3 aftershock is about 6.0km, indicating that the earthquake sequence is a seismic activity occurring in the upper crust. The results of this paper may provide data support for subsequent research of the seismogenic structures and the occurrence mechanism.
