Abstract
This study attempts to evaluate the potential risk of tsunami driven by Nankai trough earthquake with investigation of land price based on the hedonic approach in Saiki, Oita. Simulations have been conducted by the cabinet office, government of Japan and Oita local government, and results, e.g. the estimated inundation height and travelling time of tsunami, have been published. The land prices are assumed to be a good descriptor of the potential risk of tsunami as well as convenience and comfort of the life. The land prices were taken to be a function of accessibility to the Saiki train station, schools, and parks, and of risk factors, e.g. elevation, the predicted flood depth due to tsunami and so on. The multiple regression analyses show that the land prices decrease with increased distance from the Saiki station. The effect of the potential risk of tsunami is also described by the land prices, i.e. the land prices decrease as the estimated flood depth increases.
