2020年5月18日云南巧家发生MS 5.0地震,造成4人死亡、28人受伤(6名重伤员,22名轻伤员),与云南省其他地区同级别地震相比,人员伤亡比例偏高,与昭通地区历史地震相比,人员伤亡比例稍低。本文从震害伤亡人员的空间分布、伤情、伤亡原因等进行统计分析,得出云南巧家5.0级地震伤亡人员分布特征,并提出具有针对性的建议和应对措施,对提高滇东北地区地震应急救援能力,最大限度地减轻人民生命财产损失,提供参考。
On 18 May 2020, an MS 5.0 earthquake occurred in Qiaojia, resulting in 4 deaths and 28 injuries (6 seriously injured and 22 lightly injured). Compared with earthquakes of a similar magnitude in other areas of the Yunnan Province, the proportion of casualties is relatively higher; compared with historical earthquakes in the Zhaotong area, the proportion of earthquake casualties is relatively lower. In this paper, the distribution characteristics of casualties of the MS 5.0 earthquake in Qiaojia, Yunnan were obtained by statistical analysis in the aspects of spatial distribution, injuries, and causes. Targeted suggestions and countermeasures are put forward based on the characteristics. It has an important reference significance to improve the capability of earthquake emergency rescue in northeast Yunnan and reduce the loss of people's lives and property to the maximum extent.
