Study on assessment method for earthquake casualty based on epicentral intensity

In this paper,the existing methods for the evaluation of seismic casualty were reviewed.The earthquake casualties' data of China from 1990 to 2006 were collected as samples.Combined these data with several representative destructive earthquakes' data of China,the main influence factor of earthquake casualty was found out.By function fitting and regression analysis,an earthquake casualty assessment model was put forward,with the epicentral intensity as the key factor and the magnitude and population density as the secondary factors to improve the assessment results calculated from the key factor.Finally,the assessment method presented in this paper is validated by comparing the evaluation results with the real earthquake casualties' data.
