Keywords:Kumamoto earthquake, Aso volcano, landslide

The Kumamoto earthquake (Mj=7.3) on April 16, 2016 triggered many landslides at the slope of Aso Volcano. The main shock triggered more than 100 landslides of loam deposits. Earthquake-induced earthflow deposits consists of loam blocks flowed relatively long distance along the San-odani River.
