Abstract

Description is presented of ground deformation associated with ground failures in Hokkaido, a northern island of Japan during the 1994 Hokkaido- toho-oki earthquake (magnitude 8.1). The earthquake caused numerous ground failures including soil liquefaction and slope and embankment failures in a widespread area, which in turn caused damage to various structures. The structures include lifeline systems, port facilities, roadways, railways, river dikes, bridges and houses. In addition, soil liquefaction was observed in many sites where liquefaction occurred at the time of the 1993 Kushiro- oki and the 1973 Nem
