Basically, the earthquake is one of the natural disasters that have devastating effects on human settlements, causing heavy casualties and deaths on their inhabitants. At the same time, the physical vulnerability of the city has a direct impact on human-induced casualties. Usually, the vulnerability is aggravated by uncontrolled construction in faults, non-observance of standards and standards, inappropriate distribution of population and facilities in the city. An analysis of how to resist threats and mitigate their effects, based on the results, will be necessary to explain the relationship between physical and organizational resilience to this natural hazard. Now, the present study has been carried out to assess the level of urban blocks in Piranshahr. The research method is descriptive-analytical, using ANP model and GIS (Geographical Information System (GIS)), a scientific estimation of the city's resilience using spatial and non-spatial data. The results of the analysis show that 27% of the city's area has low and very low resilience, 56% moderate resilience and 17% high resilience. Hence, in the spatial dimension of the city, residential buildings and other physical elements located in old urban areas of the old age (parts of the south, west and east of the city) are more vulnerable than the newly built neighborhoods of the city (north and northeast of the city), which management Urban and national and regional planners can exploit these findings to make good use of urban regeneration.
