Eastern Siberia is characterized by widespread permafrost thawing and subsequent thermokarst development. Estimation of the impacts of the predicted rise in precipitation and air temperatures under climate change requires quantitative knowledge ab...
This study examines the characteristics of landforms affected by the 2011 tsunami along the rocky coasts of the Sanriku area in northeastern Japan. We use terrestrial laser scanning to take detailed topographic measurements of slopes near the coa...

Quantifying volumes and rates of delivery of terrestrial sediment from island arcs to subduction zones is indispensable for refining estimates of the thickness of trench fills that may eventually control the location and timing of submarine landsl...
In the last few years, SfM (Structure from Motion) based on photographs taken from UAV (Unmanned Aerial Vehicle) has attracted a tremendous amount of interest for the creation of DSM (Digital Surface Model) and other morphometric products. However...
This study investigated the spatial distribution of heavy rainfall that enhanced the occurrence of potential landslide hazards throughout Japan during the period 2001-2008, using the Soil Water Index (SWI). We calculated SWI using a tank model, w...

To quantitatively evaluate how different methods for creating 5 km mesh Radar/Raingauge-Analyzed Precipitation (R/A) affected annual precipitation, we compared three kinds of 5 km mesh R/A during 1991–2009 by devoting attention to the modification...
The empirical rainfall intensity and duration (I-D) threshold for the initiation of shallow landslide is newly defined for Japan where heavy rainfalls frequently occur during the East Asian summer monsoon season. The rainfall causes sediment-relat...
This paper proposes a statistical decision-tree model to analyze landslide susceptibility in a wide area of the Akaishi Mountains, Japan. The objectives of this study were to validate the decision-tree model by comparing landslide susceptibility a...
