Abstract

The present study aimed to investigate and zonate Tabriz city, Iran in terms of vulnerability to earthquake hazard using the GIS software. Due to the geographical location of Tabriz over the North Tabriz Fault as an active and seismic fault from the north of the city, the necessity of this issue is highlighted. Based on the 10 most important influential factors in the vulnerability of cities to earthquake (geological and environmental factors), the seismic vulnerability zoning maps were developed by the ARC GIS software using the Fuzzy logic. By the integration of the layers using the Fuzzy method, the final map of the vulnerability of Tabriz city in equilibrium earthquakes was prepared in five zones with very high, high, moderate, low, and very low vulnerability. According to the zoning maps, Tabriz is not well positioned in terms of the occurrence of earthquakes, and most of the populated areas (especially the northern and central parts of the city) have higher vulnerability.
