Decision makers need tools to understand the priorities and to set up benchmarks and track progress in their disaster management systems, so that they can justify decisions and investments. MegaIST achieves these goals by analyzing the earthquake risk in three sub-categories. Urban seismic risk, coping capacity and disaster risk management index are the main components of the system. In this study, the results for the physical risk will be presented. The physical risk is calculated for all 954 sub-districts of Istanbul with a comprehensive approach including sub-indicators such as casualties, building damages, infrastructure damages, road blockages and fire ignition probabilities. These indicators are assessed through an Analytical Hierarchy Process and compared to each other resulting Physical Risk Index based on the risk values of the sub-districts.
