Abstract :
Human earthquake, over time, faced with irreparable damages. Decision-makers have always tried to manage the crisis and challenges arising from it. Therefore, assessment of vulnerability of urban areas and planning to reduce these damage is necessary. This research was conducted with the aim of assessing the urban area against earthquake and with the crisis management approach in Tehran 6th area. For this purpose Valued, 11 criteria for degree of confinement, construction density, building quality, population density, materials and structure of the building unit, access to health centers, width of the road, building height, land use, maximum horizontal acceleration of the land and the age of the building by Delphi method. Subsequently, the indexes were analyzed using the IHWP Hierarchical Model and the criteria were overlapped in GIS software. The results of the earthquake vulnerability map showed 4.8% of the area in the vulnerability class was very low, 19% in the vulnerability class, 46.2% in the middle class vulnerability, 25.4% in the vulnerability class, and 4.6% in the vulnerability class. The vulnerability class is very large. Regarding the Vulnerability Map of Area 6, we can find that areas with a higher-wiring network and low-density distribution of low-density constructions tend to be less damaged, most of which are located on the periphery of the region or north of the 6th area. Existing districts in the north of the region are less vulnerable than the rest of the study area. As you move from north to south, the vulnerability increases.
