I think people struggle with the magnitude. Mt St Helens, for example. Not the largest eruption. But a landslide of approximately 2.5km^3 (over 3 billion cubic yards). Okay, some say, so that is a lot of earth... and then you learn that the landslide was moving at speeds of up to 160mph. That's a LOT of energy. |
