Abstract :

Background and purpose: Due to vicinity to several active faults, Tehran is treated by earthquake occurrence. The district 20 of Tehran (Rey City), where is situated in north part of central Iran, has been found as the most dangerous district which has the most blighted areas too. Assessment of earthquake risk and recognize safe and secure regions in district 20 of Tehran is this study’s purpose. Methodology: The study is an applied research model. So in this goal oriented research which has been done by descriptive analytic method, GIS and fuzzy logic and multi-criteria decision-making methods were used. The criteria which are been used in this study have been extracted based on the Delphi method and through snowball technique and based on district’s situation. Results: According to results, the district 20, has achieved a scores of 0.17 to 0.58 out of a fuzzy total score (1 score).It shows its moderate level of safety against prop gable earthquake. In contrast with the main parts of district, there are some regions in the western, southwestern and northern parts of mentioned district where are almost safer and more secure. Discussion and conclusion: Because of various faults and urban blight areas, the district 20 of Tehran is treated seriously by earthquakes. It is really vital to take some actions to implement some essential and fundamental proceedings in order to reduce the probable damages.
