Tsunami evacuation simulation combining tsunami inundation simulation and people evacuation simulation was applied to the western half of tsunami-prone area of Banda Aceh and its use for tsunami disaster education and city planning was studied in cooperation with school teachers and city office personnel. People evacuation was simulated based on multiagent simulation handling over 20,000 agent models, including walking family, motorcycle, and automobile agents. Agent ratios and their basic responses were defined in a survey of mass evacuation in Meulaboh, Nanggroe Aceh Darussalam, triggered by the May 7, 2010, earthquake. Tsunami inundation simulation theoretically replicated the 2004 great Indian Ocean tsunami as developed by Professor Shunichi Koshimura of Tohoku University who used a sophisticated source model. Several simulations were developed using different scenarios such as evacuation start timing, automobile evacuation ratios, and evacuee destinations. Simulations were shown to Banda Aceh school students and instructors and to municipal office personnel. Based on their evaluations, the tsunami evacuation simulation proved to be effective in disaster education and city planning and was improved by their suggestions. We plan to expand the simulation area to the eastern half of Banda Aceh for practical use.
