The Relationship Between Geology and Landslide Hazards of Atchison, Kansas, and Vicinity--Fig. 10

Fig. 10. Different types of landslide movement. (A) Falls occur where a block of material free-falls from a slope. (B) Topples involve rotation of a block of material along an axis at the base of the block. (C) Slides occur where a relatively intact mass of material moves along a basal failure plane. (D) Flows occur where motion is distributed throughout the landslide mass approaching fluid-like behavior.
