Mechanism of the Landslide
A landslide is a phenomenon that a slope moves partially or entirely downward because of the impact and weight of
groundwater. Sediment movement of a landslide is usually so large that damage of landslide is tremendous. Once
landslide moves, it is very difficult to stop it.
Occurrence of landslide
A slip surface formed in the ground of the slope causes a landslide. When rain or melting snow permeates through the
ground, the groundwater level rises, and the groundwater is supplied to the slip surface. As a result, the slope starts to
move. Once a landslide movement starts, it becomes larger and larger, and destroys houses, railroads, and roads at the
foot of the slope.
