ANALYSIS ON EARTHQUAKE DAMAGE CHARACTERISTICS IN QINGHAI'S SEISMIC AREA OF JISHISHAN M6.2 EARTHQUAKE IN GANSU PROVINCE
On December 18,2023,a 6.2-magnitude earthquake struck Jishishan County,Linxia Prefecture,Gansu province.The earthquake caused heavy casualties and property losses to Minhe County,Xunhua Coun-ty,Hualong County and Tongren City of Huangnan Prefecture in Qinghai Province.In this paper,the charac-teristics of the earthquake damage are discussed by field investigation and summary.The results show that the buildings of civil structure,brick-wood structure,brick-concrete structure and steel-concrete structure have been damaged to a considerable extent,and the residential buildings of rural residents have been serious-ly damaged.The collapsed houses are mainly old farm houses of civil,brick and wood structure.The severely damaged houses are mainly agricultural houses of brick and wood,brick and concrete structure,and urban residents houses.Generally,the ruined houses are mainly non-residential houses with steel and brick struc-tures.There is a definite correlation between seismic intensity and the distribution of geological hazards.The higher the intensity,the more geological hazards.
