EVALUATION OF TSUNAMI EVACUATION PLANS IN PADANG, INDONESIA

This paper presents an evaluation of the of Padang's tsunami evacuation plans. The plans consist of horizontal evacuation to tsunami free zones and vertical evacuation to the nearest shelter. Three possible epicenters are simulated to estimate the most dangerous earthquake with tsunami scenario. Base on the speed of tsunami wave and the time required to prepare evacuation, an effective evacuation time was estimated. The average walking speed of people in evacuation plan was used to estimate the coverage area of shelters and to draw a line describing the farthest point where people could reach the safety zone within the effective evacuation time. By drawing the areas where people in the areas are possible to reach the safety zone on a map, blank area where people in the area could not be safe without adding more shelters or change evacuation plan was identified.
