| Abstract: | Cities are growing rapidly, leading to the emergence of megacities, often situated in hazardous regions. Megacities host millions of people with complex infrastructure interconnections, increasing vulnerability to multiple hazards. Recognizing that disasters cannot be completely prevented, there is a need for timely response to minimize losses and speed up recovery. Effective logistics are crucial to deliver essential emergency supplies within the shortest time possible. Thus, strategically locating Disaster Logistics Centres (DLCs) is vital during disaster preparedness and emergency response. DLCs range from small (3rd degree) to large (1st degree), with 3rd degree located in high-damage areas for search and rescue, while 1st and 2nd degree DLCs are in safer, accessible locations. Despite various studies on DLC site selection, many focus on single hazards, like earthquakes in Istanbul, ignoring the multi-hazard reality of megacities. Additionally, many studies use Euclidean distance methods, overlooking the significant differences in accessibility within areas of the same distance but having difference in transportation infrastructure availability. This study used a Spatial Multi-Criteria Decision Analysis with geospatial tools to select optimal DLC sites in Istanbul, integrating Entropy, Analytical Hierarchy Procedure, and CRITIC methods to weigh criteria. The findings stress the importance of emergency roads and geophysical hazards for 1st degree DLCs, and evacuation points for 2nd degree DLCs, highlighting geohazards' critical role across all DLC levels. The study emphasizes combining expert judgments with data-driven methods and the value of geospatial tools for decision-making and stakeholder engagement to enhance urban resilience. |
