Damages by the Tokachi-oki Earthquake in Hakodate City were found mainly in the releaimed land. A remarkable exception was the case of the Hakodate College which was built on the terrace. The four storied concrete building of the college collapsed due to the earthquake, and apparently there was a serious deffect in the construction.
Many cracks and depressions of the ground happened in the reclaimed land, mainly filled-in with sand, which caused the quicksand phenomenon at the time of the Earthquake.
