Abstract

We conducted a geotechnical damage investigation for the disaster during the earthquake on June 14, 2008. An earthquake of magnitude 7.2 hit a volcanic mountain area of northern inland Japan. As a result of the earthquake, a landslide of 1.5 million m 3 generated near the top of the mountain became a mud flow and descended 10km. The geomorphic characteristics of the mud flow are reported. Another huge landslide was generated upstream near the Aratosawa dam. It was about 1.3 km in total length, about 900 m in maximum width, and a sliding mass of about 67 million m 3 slipped about 320 m. The geological features, the time series of the slide and the cause of the slide are also discussed. In this paper the geotechnical properties of the damage are introduced.
