It has been recognized as its own type of movement since the early 20th century. Earthflows are one of the most fluid types of mass movements. … See more Earthflows vary in velocity of flow depending partly on the consistency of the flow for the speed of the entire movement, usually meaning how much water is in the material of the hill slope before the slope fails.
