A new model for the tsunami propagation simulator is constructed. The boundary condition at the shore
line is controlled by the total depth and can be set to the zero normal velocity. This model, with spatial
resolution of two minute, is applied to the tsunami On December 26, 2004, 00:58 (UTC), 07:58 (Local
Time, Thailand), a great earthquake occurred off the west coast of northern Sumatra, Indonesia. The
magnitude of this earthquake was 9.0 and this was the fourth largest earthquake in the world since
1900. We deduce the shallow water wave equation and the continuity equation that must be satisfied
when a wave encounters a discontinuity in the sea depth. Our procedure also includes a new
mathematical model for tsunami generation, propagation, real-time simulation and visualization. The
model is so called SiTProS (Siam Tsunami Propagation Simulator). Thailand is one of the countries
affected by the Tsunami natural disaster on 26 December 2004. In order to provide up to the minute,
precise prediction tsunami propagation simulator model with fast and accurate prediction.
