History of the slope failure and paleoenvironment on the marine terrace of Hidaka district, central Hokkaido.

Abstract

The temporal frequency of slope failures in the terraces of Hidaka district, Central Hokkaido, and the environment inducing them were studied by tephrochronology, pollen analysis, and radio carbon dating. The morphology of the slope failures caused by torrential rains in 1981 in the area can be classified into two types: (1) deep circular gullies on gentle sloping terraces, and (2) soil slips from the surface layer in the steep slopes of dissected valleys.
