Liquefaction in Sapporo caused by poor soil conditions
The September 2018 Hokkaido Iburi Earthquake resulted in severe liquefaction in part of Sapporo’s Kiyota Ward, leaving roads caved in and homes leaning at dangerous angles. As of October 3, as many as 1,452 homes had suffered damage in Kiyota Ward. This wasn’t the first instance for the neighborhood with liquefaction observed during the 2003 Hokkaido Earthquake which had an epicenter 300 kilometers away. The liquefaction hazard map issued by the city had previously designated this area as being of high risk for liquefaction damage.
