Dependence of nearshore tsunami heights maxima on the source location

The authors continue to study the influence of the tsunami source parameters on the distribution of the wave maximal heights along the nearest coastline. Numerical tests are based on the real digital bathymetry at southern part of Japan. Mesh step is compared to 300 m in both directions. Certainly, it is not enough for inundation mapping, but quite suitable for fast evaluation of positions of wave maximal heights. All numerical tests were arranged at regular PC with a hardware accelerator, based on Field Programmable Gates Array microchip (FPGA). As was observed, both position of the sea bed initial displacement and the shape of such displacement are important. Observed phenomenon is discussed in numbers.
