Analysis Concentration Population Pattern for Mitigation Vulnerability of Urban Disasters

Prevention, mitigation and preparedness are the most important dimensions of pre-disaster management cycle. More than 75% of natural disasters have occurred in Iran; therefore, it is necessary to study about pre-disaster operation and mechanism in disaster management cycle. This paper aims to identify some patterns to decrease human presence in district 6 of Tehran and also to mitigate and prevent the probable environmental hazards effects. It was studied the district 6 of Tehran by using the dual comparison of human presence based on multiple attribute decision-making techniques. The findings show that A4 with 0.27 is the best alternative and the second alternative is A5 with 0.23 score. According to the results, it is important for planners to pay attention to the mentioned mechanisms of decreasing human presence in disasters especially in environmental hazards mitigation and prevention.
