Abstract
On April 11th, 2018, a large-scale landslide occurred in Yabakei Town, Nakatsu City, Oita Prefecture, Japan (Yabakei landslide). The characteristic of the Yabakei landslide is that occurred without any special causes such as rainfall and earthquakes. In this research, we analyzed the LiDAR UAV data (Nakanihon Air Service Co., LTD.) measured immediately after the Yabakei landslide, and considered the evaluation of secondary landslide susceptibility during the rescue activities. And I considered the cause of the time lag landslide which occurred without any special causes based on the features of Yabakei landslide. I thought that the main cause was groundwater.
