Özet: The main purpose of this study is to obtain the seismo-tectonic characteristics of Istanbul, based on earthquake risk and vulnerabilities of existing structures against a potential earthquake in the region. The hazardous areas of Istanbul with the distribution of structural damage due to different possible earthquake magnitudes with different return periods are determined and hazard maps are produced for the selected 30 districts of Istanbul. By using the Gumbel-Gutenberg-Richter approaches, in order to estimate the maximum magnitude of a possible earthquake to occur in Istanbul within a prescribed period, four different scenario earthquakes are developed according to four different return periods of 25, 50, 75 and 100 years and the earthquake risk for the province of city of Istanbul is obtained. As a result, this study reveals the damage distribution in the selected districts of Istanbul by the help of the estimated possible future earthquakes.
