Abstract :

Urban and regional resilience is one of the necessities of a sustainable human life in nature. Due to natural changes and developments, various events take place during special and sometimes sudden periods, which are necessary for the survival of the existing nature. From the past until now, several methods have been invented to deal with the damages of natural disasters, including earthquakes, and now the best way to deal with this crisis is known as crisis management by making human settlements resilient. Resilience of settlements should include all factors related to humans and society, which include social, physical, economic and institutional resilience. This research examines the physical resilience of settlements against earthquakes and ranks the vulnerability of the areas. The current research is in terms of practical and developmental purpose, in terms of descriptive research method and in terms of collecting documentary and library information. The analysis method in this research is based on the analysis of the Euclidean distances of the fault zones and Vikor method. Then, for the final conclusion, using the spatial model, the output maps of Vikor index and the earthquake vulnerability map of the settlements in the region have been integrated and presented. The purpose of this research is to analyze the resilience of East Guilan region against earthquakes and investigate the various consequences of preventing the vulnerability of settlements. Due to the earthquake-proneness of East Guilan, this area of the province has been selected for study. The results indicate that Lahijan city has the highest amount and Siahkal city has the lowest amount of physical resilience. In order to achieve physical resilience in the eastern region of Guilan, we have presented strategies, the most important of which include the creation of retrofitting plans in newly constructed buildings and strengthening the resistance of middle-level buildings and public centers, and creating access to open space, as well as strengthening and building centers. relief and treatment and increasing urban permeability.
