Landslides are classified by their type of movement. The main types of movement are falls, topples, slides, and flows.
Falls: Falls are sudden movements of loads of soil, debris, and rock that break away from slopes and cliffs. It occurs as a result of mechanical weathering, earthquakes, and the force of gravity.
Slides: This is a kind of mass movement whereby the sliding material breakaways from the underlying stable material.
Topples: Topple failure encompasses the forward spinning and movement of huge masses of rock, debris, and earth from a slope. This type of slope failure takes place around an axis near or at the bottom of the block of rock.
Flows: This type of landslide is categorized into five; earth flows, debris avalanche, debris flow, mudflows, and creep, which include seasonal, continuous and progressive.
