In this case a mass movement of ice, not rock and soil, on the Ilulissat Glacier in Western Greenland, a part of the film Chasing Ice. It is genuinely astonishing – the volume of the collapse is apparently 7.4 cubic kilometres.
Note how the system progressively destabilises. The failure event is absolutely fascinating.
Thanks to Ellen Hardy and Peter Weisinger for the heads up. My host research institute, IHRR, has arranged a showing of the film, and a panel discussion, in conjunction with the Star and Shadow Cinema in Newcastle on 18th April.
