Ataşehir is a densely populated district of Istanbul, located in one of the world’s most seismically active zones. The imminent earthquake risk presents a significant threat to public safety, urban infrastructure, and social cohesion. While the scientific community has produced risk maps and scenario studies, there is a lack of localized, citizen-engaged risk mapping and preparedness planning. This gap prevents residents from fully understanding the vulnerabilities of their neighborhoods, and hinders proactive measures by both local authorities and citizens.
