Evaluating Effective Criteria of Human and Physical Vulnerability of Tehran on Earthquake Condition

Determination of physical and human vulnerability against earthquake is significant. Classification of urban units to identify dangerous areas is necessary. In this paper, firstly the effective criteria in human vulnerability was determined, then human vulnerability and classification of earthquake danger in Tehran were specified by fuzzy model and overlaying index maps in GIS. In this research, Parameters of human vulnerability in Tehran include distance to faults, distance to main streets for each zone, population density of each region, the population density for under five years children, average number of building units, distance to power lines and the distance to gas station. Concepts of these parameters were discerned fuzzy; therefore, the fuzzy theory and more accurate Sugeno method as one of fuzzy inference method were used. In the next stage raster map of human vulnerability including the above parameters was determined. Later the reconstruction preference of Tehran regions was specified by visualization. The findings of this research show that reconstruction preference of northern regions of Tehran is more than other regions.
