the own type of landslides is flows: A flow
is a spatially continuous movement in which shear surfaces are short lived,
closely spaced and usually not preserved after the event. The distribution of
velocities in the displacing mass resembles that in a viscous fluid.
and the 2nd type of landslides is falls:
A fall starts with the detachment of soil or rock from a steep slope along a
surface on which little or no shear displacement takes place. The material then
descends largely by falling, bouncing or rolling.
hope it's help you.
