| Outline of Final Research Achievements |
Some sand layers which may be formed by the tsunami event were found in the peaty deposits under the coastal lowland in Sonobe area, Takahama-cho, Fukui Prefecture.
The coring and trench survey shows that the sand layers are distributed more than 500m to the inland form the shore. The sand include grains of the well-rounded rock fragments and organic remains such as shell, foraminifera and spine of the sea urchin, which are a lot included in the coastal sand of this area. In addition, the sand layers eroded the peaty sediments at the base, and include the rip-up clast of them.
The radiocarbon dates of the peaty sediments below and above the sand layer show that the layers deposited between the 14th and the 16th century.
