Earthquake Risk Assessment in Zhejiang Province Based on Index System

In this paper, the natural property and social property of earthquake disaster are reflected by selecting relevant indexes on the basis of risk analysis and vulnerability analysis, to represent the results of the complex interaction between the disaster factor and the hazard-affected body. Based on fuzzy theory, we use Delphi survey and AHP method to determine the weight of each index, then calculate the risk assessment value of each city in Zhejiang province. The characteristics of earthquake risk in Zhejiang province are discussed in order to provide references for reducing the risk.
