2016年1月21日青海门源MS6.4地震甘肃灾区震害特点分析

摘要

通过对2016年1月21日青海门源MS6.4地震的发震构造、房屋震害的现场科学考察，系统的介绍了本次地震的发震构造、烈度分布、建筑物震害特征、地震地质灾害分布及特点、不同烈度区房屋震害特点，并对破坏机理进行分析讨论总结此次地震灾害的特征及影响，对今后抗震设防和防震减灾工作有启示作用。%According to the scientific field survey of the seismogenic structure and housing dama-ges induced by the MenyuanMS6.4 earthquake in Qinghai province on January 21,2016,the seis-mogenic structure,seismic intensity distribution,building damage characteristics,distribution and characteristics of geological disasters caused by the earthquake,and building damage charac-teristics in different intensity zones are systematically introduced in this study.In addition,the destruction mechanism has been analyzed.The characteristics and impact of the earthquake disas-ters are summarized,and the experience and learnings for the future seismic fortification and earthquake disaster reduction are also achieved.
