Assessing the Urban Resilience against the Seismic Risks with Emphasis on Economic, Physical, and Infrastructural Dimensions (A Case Study of the Dist. 12 of Tehran)

The present research aimed to assess the quantity of indicators of economic and physical-infrastructural aspects of resilience in Dist. 12 of Tehran against earthquake which has been assessed according to the optimal rate at the universal level. In order to define the optimal rate in the research, the numerical value of each index in the regions throughout the world where multiple crises have occurred (such as Japan and California) have been considered as the optimal level of resilience for each factor. The method of research in this study is descriptive-analytical. Therefore, after doing the theoretical and empirical review of literature about the resilience, the researchers presented a conceptual model for assessing the quantity of resilience throughout the region. Giving the definitions of the criteria and factors at the economic and physical-infrastructural levels, the researchers compared the quantity of resilience against earthquake at its optimal level. The results of the findings indicated that among the economic indicators, three criteria of the type of business, the scale of business and the level of employment which had been examined were all below the optimal level. Among the physical-infrastructural indices, all indices were below the optimal level, and among them, the density index constructed with a distance of 94% from the optimal level (1) had the highest difference with the optimal level.
