Most of the existing numerical models for the simulation of Tsunami are based on the 2D shallow water equations. However, for many situations, it is necessary to use the 3D model in addition to the shallow water models to evaluate the damage in the coast region with a reliable accuracy. So, we propose the multi-scale warning system for Tsunami by connecting these models to cover the physical phenomena that have diverse scales in both time and space. In this paper, we present the formulation of the 2D shallow water wave model based on the CIP/MM-FVM with the MOC. In addition, we construct the formulation for the source term preserved the fundamental balance between the source term and the flux gradient. Finally, we apply the present model to some "real-case" numerical experiments.
