Natural disasters, specially earthquake has always been a treat for human activities, which resulting damages and losses are being seen specially in developing countries, despite technological progresses in various dimensions. Until recent decades, opinions and theories about the resulting vulnerability of earthquake was limited to physical factors, but recently, theories emphasize on the multidimensionality of vulnerability, and this is the concept of social vulnerability. The purpose of this research is to provide an evaluation of social vulnerability to earthquake in Tabriz city, and explaining the relationship of physical vulnerability and social vulnerability. This research presents a model of social vulnerability to earthquake, in zone 1 of Tabriz city, using 4 index of housing quality, population, economical-social, and access to specific land-uses and the related sub-indicators. At first Analytic Hierarchy Process(AHP) is used in order to weight indicators and sub-indicators and then final social vulnerability map is outlined after vulnerability layer(map) for each index, was created by overlapping layers in GIS. The result shows that there is a significant relationship between physical vulnerability and social vulnerability in the study area; and according to the selected indicators, the area 1 and 2 of study zone has the lowest social vulnerability and the area 5 and 3 has the most social vulnerability

In most cases, distressed areas of Iran cities make up the core and main districts of cities. On one hand, they are considered as cultural and historical heritages of those cities, therefore; it is necessary to retaining physical rehabilitation and empowerment of their performance. 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.
