2022年云南红河县M_(S)5.0地震震害特征

The Characteristics of Earthquake Damage Caused by the M_(S)5.0 Earthquake in Honghe,Yunnan

2022年11月19日云南省红河县(23.37°N,102.26°E)发生M_(S)5.0地震,打破了红河哈尼族彝族自治州21世纪以来未发生5级以上地震的记录。本文结合地震现场灾害损失调查和灾情资料收集整理,详细阐述了灾区的建筑物震害、生命线工程震害、地震地质灾害特征及原因分析,并与云南相近震级历史地震震害特征进行对比,结果表明,本次地震灾区受灾规模小,余震少,灾害损失相对较轻。

On November 19,2022,a magnitude 5.0 earthquake struck Honghe county in Yunnan Province,an area typically known for its tranquility and infrequent seismic activity.This paper integrates an on-site assessment of actual disaster losses with the collection of disaster data to elaborate on the characteristics and causes of earthquake damage to buildings,lifeline projects,and seismic geological features in the affected area.We also compared the characteristics of this earthquake's damage with those of historical earthquakes of similar magnitude in Yunnan Province.The findings indicate that the affected area was relatively confined,with a minimal number of aftershocks and a generally moderate level of destruction.Significantly,the earthquake resulted in no fatalities.
