| 摘 要： | 收集整理了2018年云南省通海县2次5.0级地震造成的31名受伤人员详细资料,对受伤人员空间分布、年龄分布、性别分布、伤情特征进行分析,得出通海地震受伤人员具有震感较强区域和人口稠密区受伤人数多、女性和老年人受伤率较高、骨折和软组织损伤居多等特征;同时,从致伤直接原因、地震强度、发震时间、人口密度、余震序列等方面对本次地震受伤原因进行分析。结果表明:震害叠加、震区人口密度高、发震时间在深夜、灾区群众对地震反应较为敏感等因素是造成此次地震人员受伤较多的重要原因。

| Abstract: | After collecting and sorting out the first-hand information of 31 people injured by 2 successive M 5.0 earthquakes in Tonghai County,Yunnan province,we analyzed the age,gender,traumatic condition,and the accident spots of the injured people.It is found that most of injured person were from the hardest-hit and densely populated areas,and women and the aged person were vulnerable,and more were suffering from bone fracture and soft tissue injury.We further analyzed the factors such as earthquake magnitude,original time,aftershocks,and population density and found that the superposition of the two earthquakes’damages,the high population density in the affected areas,the original time in the deep night,and people’s over reaction to the two earthquakes constituted the main causes of the heavy injury. |
