Analysis and study of casualties in Qiaojia MS 5.0 earthquake on May 18, 2020

On 18 May 2020, an M_S 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 M_S 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.
