Vulnerability Integrated Assessment and Making Decisions for Effective Resilience Against Natural Disasters "Earthquake" (Case Study: Tabriz Metropolis)

Abstract

One of the most important dangers that always threaten cities is the risk of an earthquake. This danger, with its high power of destruction of buildings and urban infrastructures, causes a lot of damage to cities in terms of financial and human lives. Therefore, in order to increase the capacity to deal with earthquake risks, increasing urban resilience has recently become a basic priority for most governments. Based on this, the current research was written with the aim of vulnerability integrated assessment of ten areas of Tabriz metropolis based on resilience characteristics and related physical indicators and making decisions for effective resilience against earthquakes. In this regard, the research method is applied in terms of purpose and analytical-exploratory in terms of nature. In order to analyze information, have been used AHP techniques in Expert Choice software, PROMETHEE and GAIA and GAIA Web analysis and the opinions of 25 experts. The results of the research show that areas 9, 6 and 2 have high resilience against earthquakes with scores of 0.445, 0.374 and 0.293 respectively, areas 5 and 7 have medium resilience with scores of 0.196 and 0.142 respectively, areas 4, 8 and 3 have low resilience with scores of -0.090, -0.130 and -0.236 respectively and areas 10 and 1 have very low resilience with scores of -0.468 and -0.526 respectively. Also, about 11% of the texture of Tabriz metropolis is in the zone of very high vulnerability and about 13.5% is in the zone of high vulnerability. Therefore, the research results have been able to determine the priority of measures to increase resilience for different levels by identifying vulnerable zones and regions. Therefore, appropriate policy making in the direction of earthquake crisis management is an inevitable necessity, especially in strengthening buildings and city land use planning.
