Trigger mechanisms of debris avalanche. Comparison between Bandai-san 1888 and the other cases

Journal Article:

Abstract

This report describes a trial of classifying the trigger mechanisms of debris avalanche in a volcanic action, on the basis of a geography and the structure of the sedimentation. Reason of disintegration is diversified but the debris avalanche is caused by the destruction of the unstable mountain mass. In the case of the 1888 debris avalanche of Bandai-san, a small steam explosion at the end of the strato-volcanic activity caused the instability of a part of the mountain mass, inducing a landslide. At the active period of the volcano, a viscous magma penetrates into the volcano mass, sometimes deforming the mountain body and eventually reaching disintegration. Furthermore, an eroded valley on the surface of the volcano body develops and disintegrates and, also along the slope of the volcano, a disintegration towards the sea-bottom will occur.
