The dramatic moment part of a cliff collapsed in a landslide on the north Norfolk coast has been captured on video.

Michelle Savage, from Norwich, was out walking her five-year-old springerdoodle, Frank, on the beach at Trimingham when a torrent of mud and rock came pouring down the cliff-face and onto the sand.

It happened about 4pm on Sunday, March 11.

Ms Savage said: 'The dog got spooked by the movement, so I looked to see what he was barking at and then filmed it.

'It was a really strange moment as the cliff came down - it was almost a bit sci-fi. There was a really slow rumbling and then it came down in a great mass of mud and rock.
