The paper "Temporal and Spatial Seismic Risk Scenarios of Istanbul", published in Journal of Risk Research, explores Istanbul's seismic risks through six comprehensive scenarios, incorporating both temporal and spatial dimensions. Using the Impact Chains (IC) methodology, the study examines the immediate, short-term and long-term impacts of earthquakes occurring at different times and under different conditions. The study contributes to a deeper understanding of risk reduction and disaster preparedness strategies for megacities like Istanbul.
