Breathtaking video of the collapse of a huge cliff in Cornwall England. Stay with it for a second or two. This comes, happily, with a report from a witness as follows: “Thanks for all of your positive comments. Sorry I can’t reply to them all individually. Hopefully I can answer most of the FAQ’s now…. The failure occurred at about 5 p.m. on Friday 23rd September 2011. It took place on the North Coast of Cornwall. There were only a few people watching, with about the same number of inquisitive seals in the water! There were lots of ‘small’ failures just before the main event. This appears to be a progressive failure, the frequency and size of the smaller failures increased until the inevitable happened. The sound was incredible, those cliffs are about 150-200 feet high. I’d been chatting to the couple mentioned in the clip only a few minutes before the footage was taken. They can just be seen walking away in the distance; the path had been fenced off and diverted, so they were quite safe. An amazing sight, and credit to R who took the video, I still can’t stop revisiting it! Thanks again for all the comments, who says Geology isn’t an exciting subject?”
