Abstract
Landslide disasters in Gifu Prefecture induced by the heavy rain in July, 2018 were reported. Almost slope failures occurred in the latter half of the heavy rain period. Bedrocks of the failures are granite of the Hida Belt, sedimentary rocks of the Mino Belt, and the Nohi Rhyolites. Unconsolidated materials such as terrace deposit, colluvium, surface soil and embankment were also collapsed. Furthermore, many debris flow by which the movement of valley-floor deposit probably broke out. Disasters occurred abundantly in the area of which the cumulative precipitation exceeded 300 mm, whereas they were scattered otherwise than the cases of Uwajima,Ehime Prefecture and Kure, Hiroshima Prefecture where the high disaster density.
