Not half, mate.

There's a cinema in a back street in Reykjavik called the Volcano Show, run by this filmmaker who does nothing but chase after volcanoes and make films of them. He was completely deranged, as you'd expect, but he put on a show just for us.

That's where the "volcano going off under a glacier" bit came from. He'd some footage of that, taken from the air. What happens is that the glacier melts from the underneath until, eventually, the water finds a weak spot in the ice and all bursts out at the same time!!! Imagine a river as fast-flowing as..er .. Sarn Gebir (--), except a couple of kilometres wide, bursting out in a random location and totally wiping the slate clean.
