Abstract

This research addresses the tsunami risk vulnerability of Sabang City, Aceh, which is located near the Sumatran megathrust zone, one of the areas of highest seismic activity in the world. Sabang City is at high risk of tsunamis, with most of its area falling within the high to very high risk zone. Through a Geographic Information System (GIS) approach, this study analyzed five main parameters: slope, elevation, land use, distance from coastline and distance from river to map tsunami vulnerability and evacuation routes. The analysis showed that more than half of Sabang City falls into the high and very high tsunami vulnerability categories, emphasizing the importance of effective mitigation and preparedness strategies. The evacuation route mapping produced in this study is expected to minimize the impact of tsunami disasters, especially in saving the lives of residents living in vulnerable areas.
