Locating Urban Vulnerable Areas Using Crisis Management Approach Using GIS and Weighted Overlapping Model (Case Study: region 17 of Tehran)

Region 17 of Tehran Municipality is the second district in terms of population density and 80% of worn and unstable tissue in terms of physical tissue type. Accordingly, the main purpose of this study is proper crisis management in Region 17 of Tehran Municipality, using a descriptive-analytical method and using a weighted overlap model in the GIS environment. To achieve this goal, the vulnerable areas in this area were first zoned and then from several layers including population density, quality of buildings, proximity to roads, proximity to open spaces, medical centers, fire stations and... was used in the study area. The results of the research show that the opportunities of the range are more than the threats and the weaknesses of the range are more than the strengths and the acceptable strategy for the optimal management of the earthquake crisis is in the range of the review strategy and then the defensive strategy. And in order to organize these contexts, all aspects of it, such as the social and cultural context formed in these contexts, must take into account the participation of the people in all stages, including planning and implementation.
