The British Geological Survey says there have been an unusually large number of landslides this year - after two deadly ones in Dorset this month.

Experts say Tuesday's cliff slip - which killed 22 year old Charlotte Blackman from Derbyshire at Burton Bradstock - was caused by fractures in the rock, coastal erosion and the recent wet weather.

A couple died in another at the Beaminster Tunnel two weeks earlier.
