Description
In this study,tephrochronological ages of the Koune Landslide and
the Higashiohkubo Landslide in Kamiyama Town,Tokushima Prefecture,are
estimated. The Koune Landslide is divided into two landslides; the Primary
Koune Landslide and the Secondary Koune Landslide. The Primary Koune
Landslide is cut by main scarp and moving mass of the Secondary Landslide.
The Secondary Koune Landslide is overlain by the Kikai-Akahoya Tephra and
re-sedimentation of the Aira-Tanzawa Tephra, suggesting that the landslide
occurred primarily between 7.3 ka and 26-29 ka. Therefore, the Primary
landslide is older than the Secondary one. The Higashiohkubo Landslide is not
overlain by the Aira-Tanzawa Tephra,but the Kikai-Akahoya Tepahra, suggesting
that the landslide occurred primarily between 7.3 ka and 26-29 ka.
