Bengkulu Province is classified as a province that is very prone to earthquakes and tsunamis. In order to minimize the impact of the tsunami hazard, preparedness to mitigate the tsunami hazard is needed. One of the ways is by providing information about the optimal evacuation route, assembly points and evacuation shelter buildings (ESB) and ESB capacity. The purpose of this study is to obtain an optimal evacuation route model to minimize the impact of the tsunami hazard in Teluk Segara District, Bengkulu City. The determination of the minimum evacuation route using the Floyd Warshall algorithm based on the minimum time of evacuation. In determining the minimum evacuation time, several factors are considered i.e. road width, road density, road capacity, walking speed of evacuees and group walking speed. This research produces the horizontal and vertical tsunami evacuation routes equipped with ESB capacities.
