Scientists find huge ancient landslide on Great Barrier Reef

Feb 08, 2017 - 11:00 PM

The landslide probably triggered by a massive earthquake is estimated to have occurred around 300 000 years ago

This photo taken on November 20, 2014 shows an aerial view of the Great Barrier Reef off the coast of the Whitsunday Islands, along the central coast of Queensland. The Great Barrier Reef Marine Park encompasses about 99 percent of the World Heritage-listed natural wonder, with the additional one percent outside the marine park but within the heritage-listed area -- about 3,600 square kilometres (1,390 square miles) -- being managed by the Queensland state government and includes most islands and ports, as well as lakes and other waterways.
