Abstract

The offshore-bottom of Toya Caldera Lakc at Toyako-onscncho, Hokkaido, was studied using detailed bathymetry. Lake-bottom images and subbuttom profiles show that landslide deposits are distributed in the lake bottom 0.8-1km width and over 2.2km length. The furrow surface of the large landslide deposits, similar to that of the Blackhawk landslide in California, can be interpreted as imbricate structure of sliding sediments. The formation age of the landslide deposits is unknown, but the slide was probably induced by crustal deformation or volcanic earthquake at Usu Volcano.
