Urban Vulnerability Rating against Earthquake Hazard Using ELECTRE FUZZY Model: A Case Study of Kerman City

Due to the location of Kerman city on the border of mountains and plains, there are several faults in its vicinity, some of which can cause very destructive earthquakes. The city has a very old central core in terms of architecture and is mainly made of brick and mud buildings that have a high level of vulnerability. Based on this, detailed and scientific studies of seismic vulnerability are among the necessities of Kerman urban management. Therefore, this city was chosen as the study area in this study. The information research and analysis methods were database-based methods and ELECTRE FUZZY model. In this study, quality of buildings, household density in a residential unit, width of passages, distance from the faults, distance from medical centers, access to the fire-fighting station, access to green space, access to temporary accommodation centers, and land use were examined. The results indicated that the 4th and 5th urban areas of Kerman City were the most vulnerable areas against earthquakes. The vulnerability zoning of earthquake risk in this city revealed that the areas of high vulnerability were 28 and 23% in Zones 4 and 5, respectively. More than 50% of the area with high vulnerability rating was located in these areas. Also, Urban Areas 1, 3, and 2 were in the next ranks of high vulnerability zone, respectively.
