Abstract



Natural disasters, such as earthquake, frequently inflict massive collateral damage and loss of life in cities around the world. This has triggered a wide series of studies on optimizing resistance to earthquakes in urban areas, and has urged development of efficient frameworks for building urban resilience. What is more, assisting citizens in building resilience and reducing vulnerability to natural disasters embodies a strong advocacy for urban development plan. The aim of this study is to evaluate determinants of resilience against possible earthquakes in Dehdasht city. Study type is analytical-descriptive with a practical purpose. Urban resilience is evaluated based on 14 components in terms of 4 principal dimensions by 55 experts. Statistical analysis was performed using one-sample t-test, Friedman test, Kendall's Tau and path analysis with SPSS version 22. Results suggest that the highest ratings were social capital subscale in social resilience, recovery capacity subscale in economic resilience, institutional context subscale in organizational resilience and access subscale in technical resilience. Further, average value of total resilience was significantly less than 5, the theoretical average; total resilience score was only 3.16 which indicates vulnerability of Dehdasht to earthquakes. In addition, according to experts’ ratings resilience would be significantly less after earthquake compared to before earthquake. At the end of article, we have made suggestions relative to each resilience domain, to help improve Dehdasht resilience against possible earthquakes.
