Abstract

Gansu Province, located in the west of China, is one of the provinces where earthquakes occur frequently. We try to understand the actual population in different areas of long-term and seasonal changes, building types and different structure proportion, topography and secondary geological disaster hazard factors and disaster bearing capacity by the field investigation on the border area between the Midwest of Gansu and Qinghai. This paper based on the regional seismic activity, set 6.5 strong earthquakes in every 30-50 km near the fault to determine the seismic influence field; for each seismic influence field within the scope of population, structure and topography, combine with earthquake examples of seismic disasters occurred in recent years, get the deaths, injuries and the estimated number of emergency personnel of each set of earthquakes in the study area by analogy, finally, the estimate distribution map of earthquake disaster in this research area is formed. The results can provide scientific reference value for the first time disaster assessment after the actual earthquake occurred in the area.
