Analysis of Disaster Characteristics and Disaster Reduction Counter⁃measures of Lushan MS6.1 Earthquake in Sichuan Province

2022年6月1日17时00分四川省雅安市芦山县发生6.1级地震,结合震区地质构造背景和现场调查结果,详细阐述了此次地震人员伤亡、房屋震害、生命线工程震害、地质灾害情况及致灾原因。分析认为,本次地震出现灾害的原因与当地次生地质灾害严重、部分附属房屋或构件抗震能力较弱、居民科学避震知识欠缺等因素有关。芦山县经过地震恢复重建、脱贫攻坚及农村危房改造工程等,地方整体抗震能力较好。为持续降低地震灾害风险,应提高区域建筑物抗震能力,加强地质灾害监测防治,普及科学避震知识,提升地震预警能力。

At 17:00 on June 1th,2022,a MS6.1 earthquake struck Lushan County,in Ya’an city,Sich⁃uan Province.Based on the background information of the earthquake area and the on-site investigation re⁃sults,this paper describes in detail the casualties,earthquake damage to buildings,geological disasters and causes of the earthquake disasters clearly.The analysis shows that the causes of this earthquake disaster are related to the lack of scientific knowledge of the local residents,serious secondary geological disasters,and the weak seismic capacity of some affiliated houses or components.Forth county after the earthquake re⁃covery and reconstruction,poverty engines and dangerous house renovation project in rural areas,where the aseismic ability is good,after the earthquake,the region seismic damage characteristics significantly,to continue to reduce the earthquake disaster risks,should improve the area building aseismic ability,strengthening prevention and control of geological disaster monitoring,popularize knowledge of science and suspension,improving the capacity of earthquake early warning.
