Description

Slope failures induced by earthquakes were divided into five types: the steep slope, the intermediate layer, the liquefaction, the ground water and the artificial slope. The steep slope type is the most common type of earthquake-induced slope failure. The prediction method of this type which is judged from rock hardness (interfriction angle and cohesion) and slope angles was already reported. A number of the intermediate layer type were happened on gentle slopes. They were usually large in size and the most dangerous type on the disaster prevention. It has been pointed out that the cause of this type was the failure of white tuff or pumice layer. The phenomena of the liquefaction and the ground water type are not clear, so the prediction method is the problem which should be solved in the future. When the disaster prevention of cities is considered, the artificial slope type must be a big problem. But the study is not enough.
