Abstract
In this report, we summarized the sediment related disasters triggered by the
Noto]Hantou Earthquake on March 25, 2007. However Noto]Hantou area (peninsula)
is remarked as landslide zone, many shallow slope failures were occurred rather
than large scale slope failures like the case of Niigata Prefecture Chuetsu Earthquake.
Three facilities of slope failure prevention works were damaged with crack and
0.6]1.0m steps on the rigde of steep slope. Totally, the slope failures mainly
consist of rock blocks along the coastal slope, and mainly consist of sediment
and gravel at inland slope.
Key wordsFearthquake, Noto]Hantou, slope instability, landslides, slope failure
