High resolution and high performance calculation for the Tsunami run-up simulation at Toyama-bay in Japan is achieved by using Adaptive Mesh Refinement (AMR) method and by using General-purpose computing on graphics processing units (GPGPU). AMR generated the fine grid at the boundary line between the water and the land, and the method kept the reasonably constant of the total number of calculation grids by deleting the fine grids at the far from the interested region. GPGPU realized the fast calculation of Tsunami. The method calculated more than three million calculation grids in about two minutes for five minutes simulation. And the method was about 80 time faster calculation than the CPU calculation.
