Landslide (width=150m, height=90m) occurred in Higashi-Yokoyama in Ibigawa Town, Gifu Prefecture ( 12-13th in May, 2006).  Debris from the slide buried the road in the middle, reaching to the river below. By official request from Gifu Prefecture, our team carried out field investigation on the 14th to provide a guideline for emergency measures and subsequent countermeasures. (14th May)

Debris buried a half of the river course （14th May）
