Abstract

Abstract: At 23:59 Beijing Time on December 18, 2023, an M_S6.2 earthquake occurred in Jishishan County, Gansu Province (35.70°N, 102.79 °E). Dahejia Town of Jishishan County was the macro epicenter of the earthquake, and the earthquake intensity was Ⅷ (8 degrees). Based on the preliminary field investigation of Qinghai area of Jishishan M_S6.2 earthquake on December 18, 2023, geological hazards are found in many places. The distribution of earthquake intensity, types and characteristics of seismic geological hazards are introduced. The characteristics and effects of the earthquake hazards are analyzed and discussed.

Key words: The 2023 Jishishan M_S6.2 earthquake, Qinghai region, Geological hazards, Slippage
