Evacuation Simulation for Earthquake (Case Study in Sayangan Hamlet, Kotagede Complex, Yogyakarta, Indonesia)

Abstract

Sayangan Hamlet, which is situated in Kotagede Complex Area, Yogyakarta Special Region, is exposed to the physical, socio-economic, and environmental vulnerability. A safe evacuation route to reduce the risks of earthquake impacts, however, has not supported the vulnerable condition. Therefore, the methods in this study designed an evacuation route for the hamlet by employing a staged route of evacuation model, i.e. by mobilizing victims to a temporary evacuation site first and then continued to a final evacuation site. This evacuation route model was applied in Sayangan Hamlet since the existing roads the hamlet were mostly narrow (less than 3 meters) with high and fragile walls/buildings running along the right and left sides. The result in this study: the evacuation route was organized by considering road safety, road width, and road length and accessibility to reach the evacuation site. Evacuation route map for earthquake in Kotagede expected to support disaster risk reduction.
