On December 18, 2023, an Ms 6.2 earthquake occurred in Jishishan County, Linxia Prefecture, Gansu Province, China. The earthquake was located in the Lajishan fault. To deeply into the static Coulomb stress impact of this earthquake on the surrounding faults and aftershocks, the static Coulomb Failure Stress(CFS) changes induced by the Jishishan Ms6.2 earthquake at various depths along the major surrounding faults are calculated by using elastic half-space medium and the co-seismic rupture model. And the future potential seismic hazard on the study region is estimated based on the CFS changes.The results indicate that the event significantly increased the CFS on segments of the Qinghainanshan-Xunhuananshan fault, Lajishanbeiyuan fault, and Lajishannanyuan fault. Particularly, the eastern segment of the Qinghainanshan-Xunhuananshan fault experienced a CFS increase well beyond the static stress triggering threshold, reaching 0.022 MPa, indicating a potentially higher seismic hazard. Other faults also exhibited various degrees of CFS changes, with stress unloading amounts reaching tens of thousands of Pascals on segments of the Lajishanbeiyuan fault and Lajishannanyuan fault, and hundreds of Pascals on the other segments of Nanshan-Xunhua Nanshan fault in Qinghai except the eastern segment and Zhuanglanghe fault. Furthermore, a comparative analysis of CFS changes on faults at different depths revealed a significant influence of depth variations on the CFS pattern of the earthquake. However, the increase in CFS along the Qinghainanshan-Xunhuananshan fault remains highly significant. This study provides a reference for evaluating the possibility and risk of future earthquakes in study region. Moreover, the CFS changes induced by the earthquake on the fault planes of the larger aftershocks are calculated. The CFS changes on the fault planes of the three subsequent Ms≥4 earthquake are estimated as 0.024 MPa, 0.033 MPa, and 0.034 MPa, respectively, which surpassing the triggering threshold and it shows that the Ms6.2 earthquake has obvious triggering effect on these three earthquakes.
