Abstract

Evaluation of Seismic Condition and Physical and Demographic Vulnerability in Rafsanjan City

Abstract

Today, only the urban problems are not limited in the social, economic, political, cultural issues, but natural factors which constitute the substrate of cities have a significant impact on the process as well. So the ability of cities to cope with natural hazards and proper planning is of particular importance to prevent or reduce the adverse effects. The aim of this study was to assess the seismic status of physical and demographic vulnerability in Rafsanjan City against earthquake. That's why the seismic assessment of the statistical and analytical methods and assessing the physical and demographic vulnerabilities with indicators of buildings, roads and population was conducted by using Geographic Information System Software (GIS). Also Analytic Hierarchy Process (AHP) is used to rank the vulnerability. The results show that 52.36% areas of Rafsanjan are in moderate seismic hazard zone. 47.64% area in low seismic hazard zone. In assessing the physical and demographic vulnerabilities, 13.51% areas of the city are largely affected, the 36/41% areas are moderately affected, and 50.08% areas of the city have low vulnerability However, according to the results, Rafsanjan city also has high seismic risk, but seismic analysis indicates that the probability of an earthquake with magnitude of 7 Richter scale is possible. For this reason, considering that about 50% of the city areas is vulnerable in terms of physical and functional condition so planning to reduce the risks is high important.
