Abstract :
Natural Disasters have always been a part of life on our planet. With human society development, urban areas and Metropolises have not been safe from destructive effects and consequences of disasters. In addition to intensity and extent of disasters, vulnerability of societies has remarkable dependence on proper urban infrastructures, strong structures, preventive programs and appropriate preparation in emergency-related organizations. Occurrence of an onset disaster like earthquake, usually leads to secondary damages in urban areas; they happen for an obvious reason and have specific outcomes. Identification of all significant reasons and consequences results in creating a vulnerability map for urban wards which could be a useful basis for preventive programs. On the other side, one of the most effective and efficient approaches to create preparedness and response plan disaster management organizations, is designing a relief chain with proper logistic modules and devoting responsibilities to authorities, based on data achieved from damage estimation studies. Hence, in this paper, a sequential approach is used to apply geographic information system and eliciate experts' knowledge of urban areas so as to create both damage estimation and vulnerability maps; These information. In turn, help designing disaster management cycle, specifically, Preventive, preparedness and response programs for an urban area. In order to create a better perceptive of the proposed approach, Tehran municipality district (1) is used as a real case study and its vulnerability to a hypothetical earthquake is estimated to create disaster management program.
