| Abstract: | 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 in 30 years are obtained. |
