Planning for Risk Mitigation of Fire Following Earthquake Using GIS Technique in Tehran Province

Tehran is located in a seismic zone. The importance of this city in different aspects is obvious to everyone. Earthquake occurrence would cause horrible damage to human as well as heavy financial loss in Tehran provinces. Fire is a serious threat after severe earthquakes. Due to the placement of dangerous infrastructures as well as major and minor gas/petroleum pipelines in seismic zones or faults regions, earthquake is very probable in Tehran. Therefore, an assessment of fire occurrence after earthquake is necessary in Tehran as the capital of Iran.
In order to reduce causalities and damages in this area (Tehran Province), a descriptive-analytical research method was adopted. In this regard, required plans were prepared in GIS software and data were collected from documents, books, essays, and articles. Then, three major maps, i.e. hazard map, vulnerability map, and risk map were prepared and analyzed. Finally, strategies and policies were suggested based on the SWOT analysis.
The results of this research show despite the potential danger of fire after earthquake is probable in different part of the province, the vulnerability of central parts is much higher due to the population density, accumulation of urban network path, gas and petroleum pipelines, fuel tanks, and agglomeration of industries.
This paper concludes that planning and policies about land-use allocation near hazardous zones should consider risk maps and damages. Also, the development of settlement and any construction activity require knowledge about hazardous zones and the threats of fire after earthquakes.
