$This outcrop along the Oshirakawa river east of Hakusan volcano in Japan shows textures that are common at debris avalanche deposits. Large fractured clasts are carried in a finer matrix that shows variations in color. This results from the transport of small discrete segments of the volcano for long distances without being completely broken up and mixed together. This debris avalanche was produced by a volcanic landslide from the summit and E flank of Hakusan about 4,200 years ago. Photo by S.
