广西靖西M^(S)5.2主余震震害调查对比

Investigation Result Comparison of Main Shock and Aftershocks of Guangxi Jingxi M^(S)5.2 earthquake

选取广西靖西5.2级地震主震、强余震后部分行政村震害情况进行对比发现,部分区域内4.6级余震造成的房屋破坏较主震更为严重,但人员伤亡情况较轻;选取同一区域、相同能量级的广西靖西4.0级地震造成的灾害进行对比,总结该区域内主震型与主余震型破坏的共同点及差异。通过分析震害特征,针对余震破坏特点、区域震害特征、人员伤亡情况等给出应急处置建议,为今后该区域主余震型地震应急响应及处置决策提供参考。

The damage of some administrative villages after the main shock and strong aftershock of Jingxi M^(S)5.2 earthquake was compared,it is found that after the earthquake,the house damage caused by the M^(S)4.6 aftershock in some areas is more serious than that of the main shock,but the casualties are lighter.Based on the comparison of the disasters caused by the Jingxi M^(S)4.0 earthquake with the same energy level in this county,the common points of the main shock type and the main aftershock type damage in the region are summarized,and the differences are analyzed.Based on the analysis of the characteristics of earthquake damage,the characteristics of aftershock damage,the characteristics of regional earthquake damage,casualties and other key points are given,which may provide reference for the emergency response and disposal decision-making of the main aftershock type earthquakes in the region in the future.
