THE URBAN RESTORATION IN SATOZUKA DISTRICT, SAPPORO DUE TO 2018 HOKKAIDO EASTERN IBURI EARTHQUAKE

Abstract

 As a result of the 2018 Hokkaido Iburi Earthquake, the Satozuka district of Kiyota Ward in Sapporo was suffered tremendous damage. For example, a huge volume of earth and sand spilled at the end of the embankment, with significant ground subsidence reaching more than 2 meters. After the earthquake, about half of 140 residents were forced to evacuate, and the existence and sustainability of the local community was threatened. In order to handle this severe situation, the City of Sapporo had made efforts to gain the local community’s trust and accelerated disaster recovery and restoration, sticking resolutely to “speed” in the light of the lessons learned from past earthquakes. Three months later from the earthquake, the consent of local residents regarding restoration work was obtained, and a half year later, restoration work was started and a clear vision of the work was presented. Only two years after the earthquake, restoration work was completed, providing information proactively to support rebuilding homes and personalized follow-up services for disaster victims at a local office in the disaster area. As a result, about 90% of disaster victims wished to rebuild their houses in the area, and most of the reconstruction of their houses was finished after two years and a half from the earthquake, leading to a speedy restoration of urban areas.
