The types of landslides are toppled, slide falls, and flows. The way a slides moves determines what category it falls under. Falls are sudden movements of large masses of debris, such as rocks and dirt, that break free from cliffs and slopes. It takes place as a result of mechanical weathering, earthquakes, and gravity.

Types of Landslides
Rainfall, snowmelt, water level changes, stream erosion, groundwater changes, earthquakes, volcanic activity, disturbance from human activity, or any combination of these factors can cause landslides to start on slopes that were already about to move. Sliding material separates from the underlying stable material in this mass movement.

When a structure topples, a large amount of rock, debris, or dirt is thrown forward and moved from a slope. This slope failure occurs around an axis close to or at the base of the rock block.
- The five types of landslides that fall under the category of flows are earth flows, debris avalanches, debris flows, mudflows, and creep.
- These include landslides that are seasonal, ongoing, and progressive.
- When a structure collapses, a sizable amount of rock, dirt, or other material is flung forward and moved from a slope.
- The rock block is either at or at the base of the slope collapse.
Summary:
What are the Types of Landslides?
Landslides are divided into groups based on how they slide. Topples, slides, falls and flows make up the majority of motions. Falls are sudden movements of large volumes of debris, such as rocks and dirt, that break loose from cliffs and slopes.
