Therefore, these approaches usually haveignored the capabilities and capacities of residents to reduce vulnerabilities and consequently losses and damage. Whilerecent approaches have entered, the field of disaster management emphasized that at first vulnerability is beyond thephysical vulnerabilities and second vulnerabilities have an inverse relationship with the resident’s capacity in the face ofdisaster.

Accordingly, in the first step, the indicators of community capacity and communityvulnerability are provided and in the second step based on these indicators, community capacity and vulnerability havebeen assessed. The assessment of community characters is based on GIS capabilities, spatial analysis tools and SPSSand correlation regression is used for analyzing the relationship of the variables. The results and findings of this researchindicate that the vulnerability of urban areas is not only influenced by physical factors, but also social and organizationalfactors like community organizing and community educating have affected strongly the vulnerability.
