Mass Movements in Action

A landslip described as "the worst for 100 years" has destroyed more than 400 metres (1,312 ft) of Dorset's World Heritage Jurassic Coast.
The earth movement blocked a stretch of beach between Lyme Regis and Charmouth at 2031 BST on Tuesday. The area is part of 95 miles (153 km) of Dorset and east Devon known as the Jurassic Coast, with rocks recording 185 million years of the earth's history.

Lyme Regis is built on a particularly unstable stretch of coastline and previous smaller landslips have exposed fossils on the beaches.
The coastline has seen numerous stabilisation projects in the past to stop it from crumbling into the sea.
