Description :
The 1977-1978 eruptions of Mt. Usu, Hokkaido, altered erosion regime of its summit atrio through destruction of pre-existing vegetation, new tephra deposition and crustal deformation, resulting in heavy relling and gullying. The pattern, initial rapid erosion followed by an exponential decline was observed for several other volcanoes, indicating rapid adjustment of a slope to the new erosion-sedimentation regime.
