The social and physical vulnerability assessment of old texture against earthquake (case study: Fahadan district in Yazd City)

The disasters can result in considerable damages to urban structures. In vulnerable cities, the amount of economic damages and fatalities is highlighted. The review of the literature indicates the urban vulnerabilities related to building qualification and the society situation. In this paper, some factors that can affect the vulnerability of old cities in Iran are listed. For evaluating the importance of each factor in identifying the vulnerability of Fahadan district, the AHP method is used. Twenty-five academic-related disaster management experts helped to achieve the priority of factors. Two vulnerability maps of the district were achieved by using the weight of factors obtained from the AHP model and geographic information system (GIS). Maps' analysis shows that places with high vulnerability cover all parts of the district, and residential parts of district suffer from susceptibility. Also, the results show that less vulnerable parts of the district surround the district. Reconstruction and rehabilitation measures can decrease the vulnerability value of Fahadan district.
