- Abstract:
- We use the data of buildings,population,topography,lifeline engineering systems,etc in Jianshui County of Yunnan Province,and select suitable risk factors of earthquake disaster losses,to calculate the casualties,damage to buildings,and amount of landslides with the assessment model on condition of the given seismic intensity,and get quantitative results of earthquake disaster losses.As the classical risk-assessment methods fail to help establish disaster-loss relationships for the disaster-bearers,we assess the earthquake-hazard risk using the risk-exposure amount instead of loss amount.Finally,we use the range transformation method to standardize the factors of earthquake disaster losses,and grade the earthquake hazards by comprehensive weighting.The results show that in Jianshui County there are 5 high-risk villages and towns(Qujiang in the north,Nanzhuang,Xizhuang,Lin'an,and Guanting in the south),6 medium-risk ones,and 3 low-risk ones.
