Abstract

Earthquake is a serious threat for society development and its vulnerability is influenced by environmental variables. The damages of earthquakes are reduced by recognizing these variables and area zoning. The aim of this paper is the zoning of earthquake vulnerability of Sanadaj city based on effective variables. For this purpose, the final map of region’s natural vulnerability zoning and skeletal indices and other effective social indices have been used. The variables were changed to layers of GIS and then, overlapping were performed using AHP and TOPSIS models. Finally, the vulnerability was classified in five groups from very low to very high. By comparing the results of these two models, it was revealed that these models had a similar vulnerability but they had a difference in which based on AHP model, the regions with very high vulnerability have little fragmentation in contrast with TOPSIS model. Therefore, according to AHP the most fragmentation was occurred in regions with low vulnerability. While, based on TOPSIS, the regions with average vulnerability have the most extension. According to Both models the most vulnerable areas were in the north of Sanandaj city.
