| Research Abstract |
In order to clarify the characteristics of earthquake motion which triggers landslides in the mountain areas, the seismic observation on the hill slope was carried out. And the seismic motion in each slopes of the mountain where many landslides occurred was examined by the earthquake response analysis. As a result, the seismic motion of each slope of the mountain was amplified by the effect of topology and geological structure, and the source areas of landslides tend to appear around the high acceleration areas.
