Abstract

Lake Harutori is a coastal lagoon in Eastern Hokkaido, Japan where huge tsunami attacked repeatedly with about 400-500 years intervals. The diatom assemblages from the tsunami layers contained a lot of freshwater and brackish water species. It presumed that the strong sedimentation processes occurred at tsunami events into the lake from the inland area by the back wave of the tsunami.
