Many cities are exposed to natural hazards such as earthquakes. One of the important goals of urban planning is to reduce the vulnerability and make cities resilient against earthquakes, and the first step to realize this goal is to recognize and assess the vulnerability of Khalkhal city to a possible earthquake. The main goal of this research is to assess the vulnerability of earthquake hazards with a resilience approach in Khalkhal city.
The current research is descriptive-analytical in terms of method and applied research in terms of nature. In this research, first through library studies, factors affecting resilience were identified and after preparing the research conceptual model, a questionnaire was designed in order to achieve the desired goal. Determining its statistical sample size was done using the Cochran method and the sampling method was done using the simple random method. To measure resilience, 380 citizens and 15 experts were selected as the sample size of the research among the households living in Khalkhal city. After collecting data and field information, SPSS software was used for data analysis and for drawing maps and zoning in ARCGIS software.
According to the output of SPSS in the form of a GIS map, it can be said that the central part of Khalkhal city is in low resilience and is prone to earthquakes, and many parts of Khalkhal city are in medium resilience and few parts of the city are in The state of resilience is very unfavorable; Also, according to the single-sample parametric test, the results of the research show that in the implementation of urban resilience, social, physical, economic and institutional criteria are ranked first to fourth in the resilience of Khalkhal city, and they have an effective role on the efficiency of urban resilience in this city.

Since the beginning of human being creation and beginning to live in this world, man has faced the threat of terrorism and has always tried to balance security threats and human needs. In this context, passive defense is one of the most effective and lasting means of defending against threats from a long history of human. One of the solutions has proposed to reduce injuries in the threat situations is the use of open spaces . Therefore, the purpose of the research is to evaluate urban open spaces and its role in reducing vulnerability during crisis with the passive defense approach in Tabriz . The present research is descriptive-analytical and with applied approach. Sampling were selected from 100 residents of Tabriz decuple regions from questioning surveys. The data were analyzed using ARC GIS software and multi-criteria decision making methods, MCDM and fuzzy analysis. The results showed that among the weight of sub-criteria, outdoor space has the highest weight with 0.621 value and the lowest weight was assigned to the sub-criterion of relative self-sufficiency 0.023 and according to the final map of fuzzy overly map, the area of open space in reducing the vulnerability of 10 regions was 4253469 m2 with the lowest area 5.55 percent and highest area 19.39% Equal to 14849144 m2 and has the most favorable open spaces in decreasing vulnerability, and in the among of 10 regions of Tabriz, region of 5,6,7, and 9 have an important role in decreasing of vulnerability and region of 1,2,4, 8,9 and 10 have the less effect in decreasing vulnerability.
