Preliminary Investigation and Analysis of Seismic Geological Hazards in Qinghai Disaster Area Induced by the 2023 Ms6.2 Jishishan Earthquake
At 23:59 Beijing Time on December 18,2023,an Ms6.2 earthquake occurred in Jishishan County,Gansu Province(35.70°N,102.79°E).Dahexia Town in Jishishan County was the epicenter of this earthquake,with an intensity of Ⅷ(8).Following this event,a preliminary on-site investigation in Qinghai revealed extensive damage,including collapsed houses,landslides,ground fissures,and liquefaction phenomena.The soft sur-face soil and high groundwater content exacerbated surface displacement due to the earth-quake's rupture and structural effects.This paper outlines the earthquake's intensity dis-tribution and seismic geological disaster characteristics,analyzing and summarizing its impacts.This study offers scientific insights for delineating disaster prevention areas,pre-dicting trends,and guiding post-disaster reconstruction efforts,aiding future earthquake resilience and mitigation strategies.
