Term
Rotational slump
A landslide in which a mass of soil or rock rotates along a curved slip surface. The upper part commonly drops and tilts back, while material moves outward near the toe. Water pressure can reduce the slope’s resistance to failure.
What to look for
Slumping above Redcliff Point, Dorset. Rotational movement displaces blocks along a curved shear surface; the surface scars and tilted ground provide evidence.
