Research Abstract |
Kiritani and Koinami villages in Yatsuo town, Toyama city, are located on the flat basins; they were originally dammed-lakes formed by large landslides. The ages of landslides were estimated by 14C ages of wood fragments embedded in the lake sediments and landslide debris, and they indicate that the landslides were triggered by the earthquake, probably the penultimate activity of the Atotsugawa fault. The sackungen in the Etsumi mountains along the Gifu-Fukui prefecture boundary were formed in the warm climate during or after the last glacial prediod. The dammed-lake sediments and the sackungen-basin sediments in the eastern Kii Peninsula recorded events interpreted as earthquakes and heavy rainfalls.
