Abstract
After the Tohoku earthquake tsunami in Japan, many evacuating options from a huge tsunami, e.g. tsunami tower, large building, moving onto hill, stronger breakwater, underground shelter and small lifeboat, have been proposed in recent years. In this paper, the authors have proposed and developed one kind of a large-sized tsunami shelter with mooring that is capable of accommodating at least one hundred people or more to evacuate from a run-up tsunami. The optimization for the shape of the tsunami shelter was also examined using Particle method, Smoothed Particle Hydrodynamics. The tsunami force acting on the desired shape was compared with that on the basic shape, e.g. a rectangular shape. The proposed tsunami shelter could be one of useful options for evacuating from a huge tsunami attacking near coastal area.
