Extreme Geological Events that you never knew existed.

Dr Tom Raimondo delves deeply into Australia's geological past to show how this ancient continent has been subjected to a range of extreme geological events.
He describes a subterranean mountain range near Alice Springs, a cataclysmic meteorite impact 580 million years ago that hurled ejecta over 200 kilometres, super volcanoes that produced vast amounts of lave, and giant submarine canyons that dwarf the Grand Canyon.
Australia is not such a dormant continent after all.
