Abstract

Heavy rains brought about by Typhoon Hagibis (Typhoon No. 19) in October 2019 caused great damage to the Kanto and Tohoku regions of Japan. In the Tohoku region, the rainfall was particularly high in the coastal areas of Fukushima, Miyagi, and Iwate Prefectures. In this disaster report, focus is placed on the geotechnical damage in the northern and central areas of Miyagi Prefecture. In northern Miyagi, a levee failure occurred due to overflow; the possible reasons for the breakage are discussed. In central Miyagi, a slope failure occurred due to heavy rain which led to a river revetment erosion failure; this is also discussed in the present report.
