Seems like years ago, we were watching a computer reconstruction of a historically distant inland 'sea' rupture, responsible for explaining today's observed scoured topography, and the distribution of enormous boulders and formerly ice-rafted rock, carried by the 'biblical' floodwaters; created by some college professor of geology. It was awesome.
If humans had been around at the time, to experience the event, the noise alone would have been sufficient enough to kill them, as some poor Spanish glaciologists nearly experienced on the Antarctic peninsula, when one of the Larsen ice-shelves broke off in the night.
