Translational slides

Like the layers of caramel shortbread slipping over one another in the hot sun, in a translational landslide the mass moves along a roughly planar, flat, surface with little rotation or backward tilting.

A slide-type landslide is a down-slope movement of material that occurs along a distinctive surface of weakness such as a fault, joint or bedding plane. 

If the slip surface is straight then it is termed translational or planar.

Translational landslides have occured at Nefyn, Lleyn Peninsula, Wales, along with variety of other landslide types including rotational failures, flows, falls and debris slides.
