Comparative Analysis of Casualties between Lushan M6.1 Earthquake and Luxian M6.0 Earthquake
-
摘要: 本文根据芦山6.1级地震及泸县6.0级地震现场调查资料,对比分析2次地震伤亡人员的空间分布及伤亡原因,得出避震不当是造成2次地震人员伤亡的重要因素之一。其中,芦山6.1级地震重伤及遇难人员多集中在Ⅶ度区,多数因次生地质灾害躲避不当致伤;泸县6.0级地震伤亡人员数量与地震烈度呈现正相关性,重伤及遇难人员均因房屋及其附属构件震损致伤。根据分析结果,从科普宣传、房屋及其附属构件抗震设防、次生地质灾害防治方面提出建议,为当地防震减灾提供参考。Abstract: According to the on-site investigation data of the Lushan M6.1 earthquake and the Luxian M6.0 earthquake, the spatial distribution of casualties and the causes of casualties in the two earthquakes were compared and analyzed, and it was concluded that unreasonable aviodance was one of the important factors for casualties in the two earthquakes. Among them, most of the seriously injured and dead people in the Lushan M6.1 earthquake were concentrated in intensity VII area, and most of them were injured due to improper avoidance of secondary geological disasters. The victims were injured due to the earthquake damage to the house and its ancillary components. According to the analysis results, suggestions are put forward from the aspects of popular science propaganda, seismic fortification of houses and their ancillary components, and prevention of secondary geological disasters, so as to provide reference for local earthquake prevention and disaster reduction.
