Abstract 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.

Introduction The rapid world population growth is likely to further increase the impact and severity of any disaster. Disaster management, as such, needs to be placed within a holistic setting to ensure that each and every disaster is viewed as a shared responsibility. To this aim, it is imperative to consider a number of influences, which include Beconomic, social, cultural, institutional, political, and even psychological factors that shape people’s lives in disaster situations^ (McEntire et al. 2002). Iran, Afghanistan, and India are countries with a relatively high vulnerability to earthquake hazards (UNDP 2004). Iran is a disaster-prone country, which experiences many disasters such as earthquakes every year (Omidvar 2010). Historical data show the occurrence of a major earthquake every 2– 3 years in Iran. In the 20th century alone, 20 major earthquakes claimed more than 140,000 lives, destroyed several villages and cities and caused extensive economic damages to Iran (UN Flash Appeal 2004). Most of the fatalities and damages are due to buildings collapsing, which is some 90 % of direct deaths. Advances in structural design were applied to new structures and, to a lesser extent, to the rehabilitation of existing structures. Neverthel
