N2 - In this paper, we address the problem of fast numerical simulation of tsunami wave propagation. In case of seismic event offshore Japan, tsunami approaches the nearest shore in approximately 20 minutes. Therefore, the warning system should operate even faster. The Mac-Cormack scheme was implemented at field programmable gates array (FPGA) microchip and tested against the known analytic solution. The numerical solution, obtained by FPGA method, has been compared to the one, issued by another algorithm. The expected performance will make it possible to calculate the basic wave parameters within a few minutes after earthquake.
