Abstract

The data on the 1605 Keicho Tsunami, 1707 Hoei Tsunami and 1854 Ansei Nankai Tsunami on Shikoku island were extracted from the newly discovered historical documents on these tsunamis. The inundation heights of these tsunamis measured in many villages were reexamined and reestimated by field investigation.

Accurate data which were useful for checking the validity of the numerical simulation on the historical tsunamis were offered.

As the result, the inundation heights of these tsunamis were greater in comparison with the 1946 tsunami heights at almost all of the surveyed points. This fact should be reconsidered in the future planning of the tsunami prevention.
