原因とした地すべりの調査を実施した。虎頭山・澀仔坑・草嶺で大規模な地すべりが見られ, 発生原因は直接活断層と関係したり, Bucklingが観察されることから, 地殻歪と除荷による応力開放に遠因があると推測された。

Slope failure phenomena which was caused by the CHI-CHI earthquake was investigated, and a following knowledge was obtained. The slope failures divided into two main types. The one is concurred with a large number of small-scale landslides which are moved at high speed, and the other is the enormous rock formation landslide. The fomer is mainly constituted sand and gravel layer of the plasticity or brittle hard rocks, and arise in strong motion area of above 250gal. The latter look at the pelitic rock regions. They are difficult to occure landslides caused by the earthquake in general. However, enormous landsildes arose by the CHI-CHI earthquake. It seems that is related to Buckling based on the defomation of the rock formation which is affected by fault activity and seating phemomena.
