Rating the Vulnerability Rate of the Textures of Kerman City Based of Fuzzy Logic Criteria

Urban old and problematic textures in developing countries, like Iran, are more vulnerable to earthquakes than other urban textures. The city of Kerman has become the most violent earthquake in the country due to numerous active faults and devastating earthquakes with high human casualties. Out of the total area of ​​the worn out texture of Kerman province, which is about four hundred and sixty two acres, 1589 ha are located in the city of Kerman. The necessity to reduce the vulnerability of the city against earthquakes is one of the main goals of physical and urban planning. The purpose of the study is to identify and level the vulnerability of urban tissues. The main issue is that the city of Kerman has a lot of vulnerable areas, and identifying vulnerable levels and reducing vulnerability can be effective in crisis management. The research method is descriptive-analytical one. The research data were prepared using documentary and field studies. The data of Kerman Municipality Crisis Management were used and indicators such as type of materials, population density, width of passages, type of use and structural density were investigated and maps of each of these criteria are provided using SDM FUZZY software in Arc GIS. The final vulnerability map shows that Kerman city tissues with 11.7% of cases are very vulnerable, 14.1% are highly vulnerable, 13.3% have average vulnerability, 15.5% Low vulnerability, 45.9% have very low vulnerability, which indicates the inappropriate status of the tissues.
