Short summary

The 1993 Hokkaido tsunami brought about a maximum wave run-up of 31.7m. To reproduce the extreme run-up height, a three-dimensional non-hydrostatic model has been locally applied with open boundary conditions supplied in an offline manner by a three-dimensional hydrostatic model. The diffraction of the tsunami wave primarily by islands was found to result in the extreme run-up height as in the laboratory simulation.
