"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... I'm happy to report that no seals or humans were hurt in the filming of this clip!"
