ABSTRACT

Istanbul is one of the most popular cities in the world with its location and historical buildings. However, it is one of the cities with the highest earthquake risk due to its proximity to fault lines, crowded population, and building density. To be prepared for an earthquake, it is important to understand and reduce the risk posed by an earthquake. Pre-disaster studies can provide the opportunity to keep the bad results at a minimum level. In this context, within the scope of the “Istanbul Province Probable Earthquake Loss Estimates Update Project (2019)”, done in cooperation with Istanbul Metropolitan Municipality and Boğaziçi University Kandilli Observatory Earthquake Research Institute, building damage, possible deaths and injuries, infrastructure damage, and temporary accommodation needs in districts and neighborhoods during a possible earthquake were analyzed and reported in booklets produced for each district. In this context, in this chapter, the aim was to rank the 39 districts of Istanbul from the least risky to the riskiest in a Mw 7.5 earthquake scenario considered within the scope of the project. Ranking of the districts was done using integration of entropy and combined compromise solution (CoCoSo) methods.
