An East Sea/Japan Sea Tsunami Simulator

Abstract

A study of historic and prognostic tsunamis was performed, focusing on estimates of the maximum wave height and run-up height along the Korean coast. A numerical model was created based on 2D shallow-water equations, and a run-up correction was calculated from the ID analytical long-wave run-up theory. The tsunamis of 1983 and 1993 were reproduced to validate the numerical model. The computed maximum wave heights and run-up heights agree with the observations, especially for the well-documented 1993 tsunami. Three hypothetical earthquake-generated tsunamis were used to estimate the prognostic characteristics of tsunami waves in the East (Japan) Sea. The results indicate that our tsunami simulator can be used to accurately simulate historic and prognostic tsunami events.
