The landslide at the Aratozawa Dam in Kurihara measures over 1km in length and is 0.8 km wide. The landslide body mass is around 6700 million cubic meters and the amount of displacement was around 300 meters in the main section. The landslide was translational in nature and the geology comprises hard volcanic rocks overlying soft Tertiary sediments.
