On the other hand, with the passage of time and as a result of lacking proper maintenance, most of the tissues suffer from exhaustion and collapse of their physical and functional. Along with social, economic and cultural changes and new technologies, urban tissues have also been changed since the city like other synthetic man-made phenomena will change over time. Iran's most ancient and densely populated cities have such a preparing vulnerability layer (map) for each index, final social vulnerability map is outlined created by overlapping layers in GIS. Also using TOPSIS Technique, five areas under the study have been ranked based on social vulnerability. Findings indicate that there is a significant relationship between physical vulnerability and social vulnerability in the study area. Further in unit district analysis, the area 3 has the most social vulnerability to earthquake and the others are ranked 5,4,1,2 respectively.
