The research is applied and its method is descriptive-analytical. Two methods of library and field (questionnaire and interview) were used to collect the required data. In order to assess the vulnerability of the city's neighborhoods, by designing a questionnaire using the FAHP method, in terms of physical, environmental, economic and urban facilities and equipment, 25 experts and officials who are aware of this city were asked to rate each criterion. And the preference of each of the indicators of earthquake vulnerability in the neighborhoods of Neyriz city has been determined and the final maps have been produced using GIS software and FAHP model. The results show that in general dimensions, Shahid Beheshti neighborhood with a weight of 0.0135 has the highest weight and in the first rank and Shadkhaneh neighborhood with a weight of 0.024 has the lowest weight and is in the last rank Is. Also, in terms of vulnerability of Beheshti neighborhoods, stadiums and hospitals, low vulnerability, Sardaran neighborhoods, Health and Abad Zardasht, new vulnerability, new Abad Zardasht neighborhoods, Goodagar neighborhood and Goodajar, high vulnerability and neighborhood Mahmud Khan, Sadat, Bazaar and Shadkhaneh castles are very vulnerable.
