Abstract

Hokkaido Iburi-East earthquake (MJ 6.7) attacked the south-western part of Hokkaido Japan in 2018, causing geotechnical damage by a number of slope failures in the focal area and liquefaction of manmade fills in wider areas. This paper overviews of major geotechnical damage which are mostly attributed to liquefaction-induced instability of sandy soils originated from nearby volcanic activities. Among the damage, unprecedented liquefaction-induced ground depression of a residential landfill in Sapporo city is focused because of its significant impact on liquefaction-related design.
