| Research Abstract |
This study aims to clarify the factor of seismic vibration influenced on the landslide movement. We analyzed relationships between the vibration factor of three major earthquakes (The Mid Niigata Prefecture Earthquake in 2004, The Niigataken Chuetsu-oki Earthquake in 2007, and The North Nagano Prefecture Earthquake) and landslide displacements by these earthquakes. The results showed the maximum velocity in the topographically-released direction had a significant relationship to the displacements, and was useful for the index as the seismic force for the landslide movement.
