Assessment of Seismic Population Vulnerability of Western Guanzhong

Take Baoji as an example, we select 11 main population indexes as the research objectsto study seismic population vulnerability of western Guanzhong using the Analytic Hierarchy Process (AHP) method. The results show that the population is the main factor which has influence on the vulnerability of earthquake in Baoji region; the sensitivity degree of response to earthquake is determined by population structure; social economic development level of the region restricts the recovery ability from disasters in a certain degree; the spatial population vulnerability distribution has obvious difference. Vulnerability analysis and evaluation can provide effective quantitative basis for earthquake disasters prevention and mitigation activities of western Guanzhong.
