Three-dimensional Simulation of 2011 East Japan-off Pacific Coast Earthquake Tsunami

Abstract

An article focused on the tsunami induced vortex in the Oarai port duing 2011 East Japan-off Pacific coast earthquake (Derbyshire, 2011). Also similar case can be seen in Imwon port during the 1983 tsunami event. An example of a vortex appearance can be seen when water descends into a drain. This occurs as the revolving mass of water forms a whirlpool. This whirlpool is caused by rapidly flowing water emerging from a small opening in the bottom of a basin. This swirling flow structure within a region of fluid flow opens downward from the water surface.
