Abstract

In 1914 a notable cliff fall occurred on the chalk coast of the Seven Sisters in Sussex. Debris from the fall travelled outwards across the shore platform in front of the cliff for a distance of about 75 m, forming a narrow tongue-like projection. The reason why the debris exhibited such mobility is uncertain, but it may have flowed in a similar fashion to a sturzstrom, despite its modest volume (c. 12500m3) and the equally modest height of the cliff (44-45 m). If this suggestion is correct, the minimum volume of detached rock required to trigger sturzstrom-type flow is 1-2 orders of magnitude less than is commonly claimed.
