Icebergs are notorious for keeping around 90 per cent of their bulk hidden beneath the surface of the sea. While this makes them far more dangerous to shipping than they appear, it does mean they’re extremely stable, and unlikely to wobble about. Yet even mountain-sized icebergs weighing hundreds of millions of tonnes have been known to flip over, creating tsunamis capable of swamping nearby vessels.
