An earthflow is a type of mass wasting where a mass of earth or fine-grained soil moves downslope under the influence of gravity, often triggered by saturation from rainfall. Earthflows can vary in speed from slow to rapid and are significant in shaping landscapes, especially in hilly or mountainous regions. They are also important in understanding soil stability and landslide hazards.
