Abstract

Abstract: In order to reveal the effect of regional social vulnerability on the losses caused by the earthquakes, Lushan earthquake stricken area and Ludian earthquake stricken area were selected as the study object. Based on the statistical data and field investigations, an evaluation indicator system of social vulnerability was established. Using the entropy value method, the social vulnerability of Lushan earthquake stricken area and that of Ludian earthquake stricken area were comprehensively evaluated. The results showed that the social vulnerability of Ludian earthquake-stricken area was greater than that of Lushan earthquake-stricken area, and that one of the reasons why the small magnitude of Ludian earthquake causedHeavier casualties was the greater regional social vulnerability.

Key words: social vulnerability, comparative analysis, entropy method, Lushan earthquake, Ludian earthquake
