Rotational slides

The 1993 landslide at Holbeck Hall, North Yorkshire.

A slide type landslide is a down-slope movement of material that occurs along a distinctive surface. If this slip surface is curved the slide said to be rotational.

The slip surface of a rotational landslide tends to be deep. Blocks of failed material can rotate as they fail and can at times be seen to tilt backwards towards the slope.

A good example of a rotational landslide is the Holbeck Hall landslide, in Scarborough North Yorkshire, England. The 1 million tonnes of cliff failed as a rotational landslide over a couple of days in June 1993 and destroyed the Hotel at the top of the cliff. The rotated blocks can be seen as grass covered 'benches' in the photograph.
