Tsunamis cause various damages, resulting in a heavy toll in human live in many areas. From post tsunami surveys, it is also confirmed that some coastal and harbor structures, sand dunes and coastal vegetations can reduce the tsunamis behind them and mitigate disasters there. To prevent and mitigate tsunami disasters especially in the area that a tsunami comes soon after an earthquake occurs, structural measures to control tsunamis and non-structural measures to save human lives should be integrated depending on topographic, social, economical and cultural characteristics of the area.
In this paper, a dynamic hazard mapping technique is developed to help the understanding of vulnerable areas against not only the worst tsunami in the area but possible tsunamis and the enhancing of people's tsunami awareness to increase preparedness against possible tsunamis.
