Ice shelf video

https://www.youtube.com/watch?v=anfbjiShjP8 I've seen video of a town size ice shelf breaking away. It's kindof striking; you can see the effects of energy stored.  Everything is slow moving, and you wouldn't expect some of the pieces of ice to move in the ways that they do; but, there's so much energy stored in there, that they move in some odd ways.  I'll try to find that video. I might be able to.  But, the above with the rift is striking enough.  You can see what a ice shelf about to break away really looks like - not the breakaway you see in "Day after tomorrow".
