Abstract

The fact is revealed that the current crisis management cannot alone be able to deal with the destructive effects of disasters in order to To prevent destructive effects on vital and sensitive centers and manpower, therefore, it is important to apply the principles and criteria of passive defense, which can help to complete the chain of urban defense effectively and significantly. Most of the existing researches related to the reduction of damages caused by earthquakes have focused on building construction methods to increase the resistance of the building against earthquakes. In this research, with an emphasis on passive defense and identification of components and indicators of vulnerability and risk zoning in 4 natural, physical, social and economic components with 48 indicators, in the form of a questionnaire, the vulnerable areas caused by earthquakes were comprehensively identified in line with Determined to reduce risk. In this article, the necessary investigations and analyzes are carried out by applying the opinions of experts in the field of urban planning and passive defense, etc., through the distribution of 30 questionnaires and the help of GIS software in processing and preparing the output of ARAS and TOPSIS models at the level of the metropolitan areas of the city. Tabriz has been used and finally, according to the results of Aras and TOPSIS models, district 10 of the municipality of the crisis zone and district 2 of the municipality have the lowest level of vulnerability to earthquakes. In the following, the factors of this increase in vulnerability and solutions to overcome the crisis at the level The ten municipal areas were presented according to the principles of passive defense and the output of the models.
