Relocation of the 2023 Ms6.2 Jishishan Earthquake Sequence in Gansu Province
This study used the double-difference earthquake location method combined with waveform cross-correlation technique to relocate the Ms6.2 Jishishan earthquake sequence(As of 24:00 on December 22,2023)in Gansu Province.The results show that the epi-center of the Ms6.2 Jishishan earthquake is located at Jishishan County,Linxia Prefecture(35.745°N,102.827°E)and the focal depth is about 12.5 km.The aftershock sequence formed two branches in different directions,which were NW and NNW.The aftershocks near the Ms6.2 Jishishan earthquake are distributed in an NW direction,and tilted toward the NE.The relocation results reveal the complex tectonic environment of the region.
