- Abstract:
-
In this paper,we choose the economic losses caused by medium-strong earthquakes in Yunnan from 1992 to 2016 as sample data to analyze the characteristics of the per capita economic losses. According to the population density,the GDP value,and the economic losses in each county and city in Yunnan province,we divide it into six sub-regions. Then,through multiple linear regression analysis,we propose a rapid pre-assessment model of per capita economic losses caused by earthquakes. The model includes parameters like magnitude,intensity of the mezoseismal area,per capita GDP,per capita revenue,and per capita net income of farmers. Finally,we compute economic losses of the M≥5.0 earthquakes since 2010 with our model,and compare the results with the corresponding actual ones. We find they are close to each other. This proves that our model is practical for a rapid pre-assessment of economic losses in the Black-box stage of post-earthquake emergency.
