Abstract
This paper presents the proposal of an applicative tsunami wreckage simulation and damage estimation. In order to determine the volume of wreckage and the some parameters such as the condition of wreckage motion, some studies were carried out by the previous paper. Some kind of properties of wreckages such as the position and the type of wreckage were difined by using extention function of GIS. For the presented study, the tsunami wreckage simulation and damage estimation of Nanka Trough Quake was carried out. The validity of applicative damage estimation for tsunami wreckage was presented in this paper.
