 note = {application/pdf, Natural disasters caused by huge earthquake have occurred in various places, and has made a great impact on social activities and people's lives in recent years in japan. Then the effect on transportation caused by disaster on earthquake is very high. The Hokkaido Eastern Iburi earthquake in 2018 caused geotechnical disasters, which are large slope failures in wide area, and unique liquefaction at Satozuka area in Sapporo city etc. In particular, serious geotechnical damages were induced in Atsuma town recorded 7 on the Japanese seismic intensity scale (a magnitude of 6.7). The objective of this study is to investigate factors for geotechnical disaster due to 2018 Hokkaido Eastern Iburi earthquake in these region. In this study, geomorphic and geological investigation for factor of slope failure occurred in the Atsuma town and that of liquefaction at Satozuka area in Sapporo city is discussed. In the survey, it is found that the large slope failure occurred in the Atsuma town is caused by Ta-d unit of Tarumae volcanic ash layer, and the type of slope failure is surface failure., 特集},
