Amazing Cliff Collapse Caught on Video

This amazing video of a cliff face collapsing into the Celtic Sea was filmed by an amateur photographer in Cornwall, England, on October 4, 2011. The incredible footage shows a large chunk of the North Cliffs breaking away and tumbling hundreds of feet below, causing a mini-tidal wave.
Engineering Geologist Pete Hobbs with the British Geological Survey told iWeather Online that the rock slide was most likely associated with a “wedge failure”. Mr. Hobbs said the collapsed material comprised “a mixture of slate and sandstone, and was Devonian in age”. The video is one of the best examples of a rockslide I have seen in the UK. Initial estimates would suggest that between 50,000 to 100,000 tonnes of earth and rock slid into the sea. It was so large that it produced a wave, which radiated out in a semi-circular front out to sea”, Mr. Hobbs stated.
