“…The layer below the slip surface had a lower hydraulic conductivity and the difference in the hydraulic conductivity was the dominant control on the slip-surface layer (Shimizu and Ono, 2016). Furthermore, Sato et al (2017 and observed that the gravitational deformation of the slope deposits on the Aso volcanic mountains resulted from the " ow" of the highly permeable kuroboku layer over the less permeable tephra layer.…”

Shallow landslides are known to appear frequently on the Aso volcanic mountains. The soil material on the Aso volcanic mountains consists of tephra layers obtained from volcanic activities. This study is aimed at determining the soil property factors that correlate with the slip surface of a shallow landslide on the volcanic mountain area. Tephra layers consist of kuroboku and scoria layers and the differences between these layers have been determined using soil property tests. This study determined that the plasticity index and the fine fraction content can be used as factors showing the slip surface indication in the Aso volcanic area.

Shallow landslides occur frequently on the Aso volcanic mountains. The soil materials on the Aso volcanic mountains consist of tephra layers formed by volcanic activities. This study is aimed to specify the physical properties of soil that correlate with the sliding layer of a shallow landslide on the volcanic mountain area. Tephra layers consist of kuroboku and scoria layers and the differences between these layers were specified using the physical properties of soil methods. Results showed that the plasticity index and the fine fraction content can be used for estimating the sliding layer in the Aso volcanic area.
