The 2004 Indian Ocean tsunami caused significant damages to Thailand. This great experience enhances the necessity of an early warning system. This paper describes three techniques for developing the tsunami warning system (Numerical modeling, Neural network modeling and web-based online displaying). Hypothetical earthquake and tsunami sources are obtained from past events and are mostly concentrated in the Andaman microplate. The GRNN is seen to provide reasonable predictions of wave heights for variable location, magnitude and depth of earthquake. The obtained online tsunami database warning system will be very useful for Thailand's response measure against the future damages.
