Folkestone Warren Landslide
The Folkestone Warren landslide is one of the largest on the English coast and is a classical example of a deep-seated (approx. 40 m below sea level) multiple retrogressive, compound mechanism, having translational, rotational, and graben features.
The Folkestone Warren cliffs are divided into the chalk 'High Cliff', essentially the overall landslide backscarp, and the sea 'cliff' consisting largely of landslipped material. The 'High Cliff' as such is not directly influenced by the sea, unlike the Folkestone Warren landslide as a whole.
The landslide has been extensively studied since 1915 when a major re-activation occurred throughout the complex seriously disrupting the railway constructed in 1844. Since its construction the railway has been regularly disrupted by landslide activity, and considerable expenditure has been, and continues to be, involved in remediation and monitoring. The old Dover road is situated close to the cliff edge. This has also been disrupted, and re-routed in parts, for the same reason.
