摘要
2019年11月25日广西靖西市发生M^(S)5.2地震,造成一定程度的灾害损失和人员伤亡。利用地震现场工作获得的第一手资料,结合地震科学考察、震害补充调查资料及仪器烈度速报成果,在公开发布的地震烈度评定结果基础上,重新修订靖西M^(S)5.2地震烈度分布图,分析房屋震害及地震次生地质灾害特征,讨论B类房屋较A类房屋震害偏重的原因,及地震次生地质灾害现象评定地震烈度的局限性,探讨地震烈度快速评定技术的发展趋势。
On November 25,2019,an M^(S)5.2 Earthquake occurred in Jingxi City,Guangxi Province,causing a certain degree of disaster losses and casualties.In this paper,the intensity distribution map of M^(S)5.2 Jingxi earthquake had been revised based on the publicly published seismic intensity evaluation results and the first-hand data obtained from the field work of earthquake,combined with the scientific investigation,supplementary investigation data of the earthquake damage and quick report of instrument intensity.the characteristics of buildings damage and post earthquake geological disasters had been analyzed,the reasons why the earthquake damage of class B buildings is more serious than that of class A and the limitations of the phenomenon of post earthquake geological disasters in evaluating earthquake intensity had also been discussed,in addition,the development trend of rapid evaluation technology of earthquake intensity had also been analyzed in this paper.
