通过多种渠道收集并整理2021年全球地震灾情信息，对比分析国外历年地震灾害情况，根据2021年度国外重大地震灾害事件，总结其灾害特点，可知2021年国外地震灾害程度与前2年相比有所加重，地震灾害相对集中，灾区房屋抗震性能差与次生灾害重是导致人员伤亡的重要原因。
This paper collects and organizes the worldwide earthquake disaster informations from various resources in 2021,compares and analyzes the foreign earthquake disasters in past years,describes the significant foreign earthquake disaster events and summarizes the characteristics of foreign earthquake disasters in 2021.Compared with the past two years,the degree of foreign earthquake disasters has increased in 2021.The earthquake disasters are relatively concentrated.The poor anti-seismic capacity of houses in affected areas and serious secondary disasters are important reasons for casualties.
