Three Large Historical Landslide Dams and Outburst Disasters in the North Fossa Magna Area, Central Japan
International Journal of Erosion Control Engineering Vol.5, No.2, 2012 Disaster Report Three Large Historical Landslide Dams and Outburst Disasters in the North Fossa Magna Area, Central Japan Kimio INOUE1, Toshio MORI2 and Takahisa MIZUYAMA3 1Sabo Frontier Foundation (Sabo-Kaikan, Hirakawa-cho 2-7-4, Chiyoda-ku, Tokyo 102-0093, Japan) Email: [email protected]) 2Sabo Frontier Foundation (Sabo-Kaikan, Hirakawa-cho 2-7-4, Chiyoda-ku, Tokyo 102-0093, Japan) 3Division of Forest Science, Graduate School of Agriculture, Kyoto University (Kitashirakawa, Sakyo-ku, Kyoto 606-8502, Japan) Large landslides or debris flows caused by heavy rainfall or earthquakes often block rivers in mountainous areas and form landslide dams. The area upstream of the landslide dam is submerged under water and the downstream area is flooded when the landslide dam breaks. In recorded history, as many as 22 landslide dams have formed upstream of the Shinano River and the Hime River, in the northern part of Nagano Prefecture in central Japan, and all except three have subsequently broken. This abundance of landslide dams is probably caused by the geotectonic background of this area, which is located at the western end of the “Fossa Magna” major tectonic line. In this study, we examined three large historical landslide dams and outburst disasters in the north Fossa Magna area. Keywords: Landslide Dam, Debris Avalanche, Tobata Landslide, Zenkoji Earthquake, Mt. Iwakura Landslide 1.

Chiba-shi is a port and administrative centre in southern Kanto, the largest city in the eastern part of the Tokyo Metropolitan Region and located about forty kilometres from downtown Tokyo. The study privileges the role of process as a theoretical basis for exploring the dynamics of the production and transformation of urban space. -

The studied area is Shonai and Shin river basin- hereinafter referred to as the Shonai river system. It locates about the center of Japan including Nagoya city area, 5th largest city in Japan with the population about 3millions. Therefore, two rivers flow through densely populated area and into the Pacific Ocean and are typical city-type rivers in Japan. Shin Riv. Border of basin Shonai Riv.
