A group of friends from East Yorkshire have told of their lucky escape when a cliff collapsed metres from where they sat on a beach.
The friends were sitting under a cliff in Mappleton near Hornsea on Sunday when it began to crumble.
They said they moved from the area seconds before tonnes of clay and rock fell to the ground.
East Yorkshire Council said people had to be careful when they were near eroding cliffs.
Cliff 'just fell'
Angie Goodwin, who was with her daughter and friends at the time, said: "We ran, sprinted. We had a couple of seconds warning before shrapnel and boulders began falling in front of us, and then the whole shelf of the cliff just fell."
A crutch used by one of the girls was trapped underneath the fall along with the group's beach towels.
Mike Ball, of East Riding of Yorkshire Council, said: "I think people have to exercise responsibility on their own part. It's the same when you cross a road.
"Roads are inherently dangerous - you have to take care when you are in the vicinity of one."
