摘要
系统收集、整理了中国大陆2011—2020年地震人员伤亡资料,分析了中国大陆地震人员伤亡的时空分布特征,探讨了伤亡与震级、烈度的关系。结果显示,2013、2017年人员伤亡地震频次较高,但人员伤亡主要集中在2013、2014年。区域上人员伤亡地震主要集中在西南地区的云南、四川两省,死亡、受伤人数分别占死亡、受伤总数的90.57%、86.32%。地震人员伤亡数、单次地震伤亡数与震级、极震区烈度呈正相关关系,且不同区域各烈度档优势伤亡分布区间基本一致,但不同区域相同震级伤亡成灾概率差异较大。
On the basis of systematically collecting and sorting out data on casualties from earthquakes in China's Mainland in 2011—2020,we analyze the temporal and spatioal distribution of casualties caused by earthquakes in China's Mainland,discusse the relationship between the casualties and the seismic parameters,such as the magnitude and intensity.The results shows that the frequency of earthquakes with casualties is relatively high in 2013 and 2017,but the casualties are mainly in 2013 and 2014.In the regions,earthquakes with casualties mainly occur in Yunnan and Sichuan provinces in the southwest of China.The deaths and injuries account for 90.57%and 86.32%of the total deaths and injuries,respectively.The number of casualties caused by earthquakes and the casualties in a single earthquake are positively correlated with the magnitude and the intensity of the extreme earthquake zone.The distribution range of the dominant casualties of each intensity profile in different regions is basically the same,but the probability of casualties of the same magnitude in different regions is quite different.
