Any City may be subjected to various natural hazards. Earthquake is one of the most important hazards that hit our cities in Iran. Tehran as a metropolitan is not excluded from this role. Meanwhile because of some spatial characteristics such as many faults in north and south of Tehran, structure density, regardless of standard, improper physical expansion, etc it is more vulnerable. On the other hand, the latest quire of the city occurred 175 years ago, the return period of such quake is about 150 years.
In this paper, structural characteristic of different part indices, vulnerability, material résistance, Different zone of Tehran has been classified according to material resistance and vulnerability to a hypothetical earthquake.
Finally some strategies for delimiting, suitable planning and crisis management methods for such hypothetical quake have been introduced. In this research we considered spatial aspects of natural hazards. Among these aspects is distance to faults.
