The Tokachi-oki eathquake in 2003 brought tsunami to wide areas along eastern coasts of Hokkaido, Japan on September 26, 03. This numerical animation shows the possible evolution of the earthquake tsunami until 106 min after an occurrence of the earthquake. A non-linear long wave equation involving turbulence and Coriolis effects is computed implicitly by using Fractional Step method, LC method and CIP method. An initial displacement of the sea bed is determined on the basis of an earthquake fault model provided by Geographycal Survey Institute.
