Evaluation of Potential Risks due to Earthquake in old Textures

Regarding the probability of a large earthquake over magnitude 7 (in case of north and south of Tehran faults activation) and several active faults, Tehran is a vulnerable to earthquakes and its consequences due to weaknesses of structure. However, according to researches of Japan International Cooperation Agency (JICA), the biggest damage from the earthquake will occur in case of Rey fault activation. Situating the old textures in high-risk areas in Tehran and lack of needed infrastructure are the major problems of urban old textures, which raise the importance of these issues.This paper aims to investigate the properties of old textures and apply the available methods and approaches in order to evaluate the potential risks caused by earthquake by using a conceptual model for determining potential risks qualitatively in Eastern Sanglaj in district 12 of Tehran.According to the results, blocking of the passage and demolishing the buildings are severity of the potential risks for the studied area respectively.
