Abstract:: Based on statistics of frequencies of earthquake disasters and their damages within 2013 in China, we analyzed the spatiotemporal distribution characteristics of earthquake disasters, and discussed the damage differences among provinces. The conclusions can be drawn as follows. Moderately strong earthquakes were abnormal active in 2013 in mainland China, especially the Lushan earthquake in Sichuan Province caused huge number of casualties and economic losses. The number of aftershock affected earthquake frequency on the time scale and the energy distribution released by earthquakes were influenced by macro earthquake. Most earthquakes happened in western China and macro earthquakes were active in Chinese North-South seismic belt, with a disciplinary spatial distribution. Most of earthquakes occurred in Sichuan, Yunnan and their border lands. Moderately strong earthquakes were also active in Jilin. In most provinces, slight earthquakes occurred more frequently while the great earthquakes were seldom. It can be found that the economic losses caused by quakes were associated with the energy liberation through earthquakes as well as the development condition of economy in different provinces. Damages in Sichuan and Gansu are the most severe in terms of casualties and property losses, followed by Yunnan and Jilin.
