15.1 What are the characteristics of mass movements?
- Rupture surfaces
- Slides move along a rupture surface
- May be a planar surface like a bedding plane, or a rock joint or fault
- Can also be a curved surface
- Commonly on unconsolidated soil or regolith
- The mass rotates along the curved break
- Such a rotational slide is called a slump
