Analysis with Geographical Detector on the Influencing Factor of Earthquake Mortality in China

摘要

This paper collected earthquake cases related data in China mainland from 1993 to 2015, we used three geographical detectors (risk detector, factor detector, and interaction detector) based on spatial variation analysis of some potential factors to assess quantitatively their effects on the mortality. It was found that three factors are responsible for mortality: earthquake intensity, house destruction area, and indoor rate. While not observing the population density and the level of economic development in the area of earthquake. There was interaction between factor, mainly for synergies and nonlinear synergies. The social factors enhanced the contribution of natural factors to the mortality rise, and both social factors and natural factors lead to rising the mortality. The study, despite some limitations, has important implications for both researchers and policy makers.
