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.
