Crisis planning and management of natural disasters with emphasis on earthquakes that cause human, financial and environmental damage to spaces and residents of urban areas, should be considered as a basic strategy in all stages of planning and Urban development programs should be considered especially for worn-out structures. The safety of cities, especially dilapidated and historical texture against hazards and crisis management is one of the goals of urban planning and in this regard, the first step is to know the resilience of worn texture neighborhoods and its management against hazards. This research is applied in terms of purpose and descriptive-analytical in terms of research method. The approach of this research is documentary and field. In order to properly manage the crisis in District 19 of Tehran Municipality, using the weighted overlap model in the GIS environment, the vulnerable areas of the area were zoned. In this model, several layers including population density, quality of buildings, proximity to passages, proximity to open spaces, medical centers, fire stations, etc. have been used in the study area. The results of the research show that only a percentage of the study area has a favorable to very favorable condition. And a larger percentage of the study area is in unfavorable to very unfavorable conditions. Due to the fact that most of the 19th district of Tehran Municipality is in a moderate to very unfavorable condition, so it demands the importance and attention of city officials. In order to prevent the destruction of worn-out or even residential structures with the necessary preventive measures and programs, so that we have the least amount of financial and human damage and crisis management in the region.
