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

It's been found that the cliff slip which killed 22 year old Charlotte Blackman from Derbyshire - at Burton Bradstock on Tuesday - 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.
