Active Coastal Erosion in Cornwall. See 'North Cliffs 3hrs Later' video on my channel also. Very lucky to witness 1000's of tonnes of rock falling into the Atlantic! 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 5pm 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 150-200ft 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?!. Oh, & finally..... I'm happy to report that no seals or humans were hurt in the filming of this clip! ACSM(93)
