The National Trust is urging people to stay away from a closed section of beach at Burton Bradstock where there has been a large rockfall today.
A National Trust ranger discovered the very large rockfall on a routine monitoring visit to Burton Bradstock this morning at about 11am.
Coastguard and emergency services have been informed and the National Trust said they were working with them.
A spokesman for the Trust said: “We would urge people to stay away – the beach and South West Coast Path between HiveBeach and FreshwaterCaravanPark is closed.
“People visiting the coast really must take moment to read warning signs in car parks and on nearby paths and to follow the advice for their own safety.
“It highlights that this is a very dynamic and changing environment – the coastline is constantly eroding and it is very difficult to predict when these incidents will happen.”
