Based on data of seismic disasters from 1990 to 2009 in China,linear fitting between seismic intensities and mortalities was performed.And a vulnerability curve of seismic mortality,which was appropriate for seismic risk assessment,was established.Seismic mortality risks were assessed quantitatively at the county level using the model and the spatial patterns were analyzed.Seismic mortality risks of 2355 counties with intensities from Ⅴ to Ⅺ were analyzed thoroughly.This study indicates that under different seismic intensities,China’s eastern and central regions are generally confronted with higher risk than western regions.High-risk areas are scattered in Shandong and Jiangsu,northern Anhui and eastern Heilongjiang and Jilin,where populations are dense and the environment is conducive to disasters.Risk- free areas displayed patchy distributions nationwide,and patterns were mostly unchanged. %U https://www.jorae.cn/EN/10.3969/j.issn.1674-764x.2011.01.012
