Warning over 'dangerous' Skipsea cliff erosion
People are being warned to keep away from cliffs along part of the East Yorkshire coast after about 10ft (3m) fell into the sea in the past month.
Heavy rain and high tides were blamed by local residents for the cliff-face collapse at Withow Gap, Skipsea.
Conservative councillor Jane Evison, portfolio holder for tourism on East Riding of Yorkshire Council, said the cliffs were "extremely dangerous".
It would be made clear at the site that the cliffs were not safe, she said.
The cliffs, which are designated a Site of Special Scientific Interest due to their geology, are regularly used by walkers and dog owners.
Judith Foreman, whose farm is located at the top of the cliffs, said "large chunks" had disappeared into the North Sea over the past few weeks.
"It's absolutely terrifying to see how fast it's going," said Mrs Foreman.
A drop of about 10ft had now formed between the cliff path and the beach, she added.
Mrs Evison said the council had been aware for some time that the cliffs along that stretch of coast were eroding "at an accelerated rate".
The safety of the public had become a concern, she said.
"I give my assurance that somebody will be out there as soon as possible to have a look to see what needs to be done to make the general public realise it certainly is not safe," said Mrs Evison.
