                    本文在统计分析2020年中国5.0级以上地震目录的基础上,结合有关省(自治区、直辖市)地震局地震灾害损失评估资料,总结2020年中国大陆地震灾害情况和主要特点。总体全年地震灾害程度较轻,但小震致灾致亡的现象突出。将1991—2020年中国大陆地震灾害相应数据和特性进行比较,得到中国大陆致灾地震频次、伤亡情况和经济损失变化趋势。
                
                Based on the statistical analysis of the catalogue of earthquakes above 5 magnitude in China in 2020,combined with the data of earthquake damage assessment of the Seismological Bureau of the provinces(autonomous regions and municipalities directly under the central government),the earthquake disaster situation and main characteristics of the Chinese mainland in 2020 are summarized.On the whole,the degree of earthquake disaster in the whole year is relatively light,but the phenomenon of disaster and death caused by small earthquakes is prominent.Finally,the corresponding data and characteristics of Chinese mainland earthquake disasters are compared in 1991—2020 years,and the frequency,casualties and economic losses of the Chinese mainland earthquake disasters in30 years are obtained.
