Abstract: Since the earthquake disaster frequently occurred in China, it is necessary to do some research on the risk analysis of earthquake. The paper first analyzed major factors of earthquake disaster, then established earthquake disaster risk assessment model based on the data of earthquake disasters between 1900 and 2009, and determined the value of three factors quantitatively. Finally, through using the spatial analyst function of ArcMap system, this paper analyzed the risk of population in earthquake disaster and created the population risk distribution map with a division of population high risk areas.

Key words: China, earthquake disaster, geographic information system, population hazard, population risk
