Longitudinal distribution pattern of hummocks of Kannongawa debris avalanche deposits, Nasu Volcanic Group, Japan

Abstract

The hummocky topography shows some meaningful geomorphological aspects about the collapse and debris avalanche. This study tries to find some aspect of “valley-filling” debris avalanches on the basis of longitudinal distribution pattern of hummocks, selecting the Kannongawa debris avalanche, Nasu Volcanic Group of Japan, as a study case.
