N2 - The authors have implemented the nested grids approach for fast calculation of tsunami wave propagation. FPGA based hardware accelerator is used to achieve acceptable (high enough) performance at regular modern PC. Numerical experiment is based on the real digital bathymetry around the northeast part of Japan. Mesh step variation is from 276 m to just 17 m. Realistic shape of the initial sea surface displacement at tsunami source was used. Observed phenomenon is discussed in numbers.
