Estimating the impact force generated by granular flow on a rigid obstruction
Flowing sediments such as debris and liquefied soils could exert a tremendous amount of force as they impact objects along their paths. The total impact force generally varies with slope angle,Expand

Landslide susceptibility analysis with logistic regression model based on FCM sampling strategy
We present the Fuzzy c-means (FCM) algorithm as an optimal method for choosing the appropriate input landslide points as training data for landslide susceptibility mapping in Mizunami City, Gifu Prefecture, Japan. Expand

InSAR-derived digital elevation models for terrain change analysis of earthquake-triggered flow-like landslides based on ALOS/PALSAR imagery
Earthquakes can directly trigger multiple simultaneous slope failures in mountainous regions. Among these slope failures, flow-like landslides with high velocities and long run-outs can result inExpand
