LAKE ACRAMAN in South Australia is Armageddon for the purist. No other meteorite impact on Earth has stamped the surrounding rocks with such an abiding, unequivocal record of collision, quake, wind, fire and tsunami. The story it tells is elemental--without dying dinosaurs or even Bruce Willis to complicate its simple message of destruction. First, the numbers: a rocky meteorite more than 4 kilometres across and travelling at around 90 000 kilometres an hour slammed into an area of red volcanic rock about 430 kilometres northwest of Adelaide. Within seconds the meteorite vaporised in a ball of fire, carving out a crater about 4 kilometres deep and 40 kilometres in diameter and spawning earthquakes fierce enough to raise 100-metre-high tsunamis in a shallow sea 300 kilometres away...
I think there is a **good** chance the crust just got cracked..... ps I doubt this is the **biggest** meteor to hit the earth either.
