Scientists have discovered evidence of a massive ancient undersea landslide next to Australia’s Great Barrier Reef. The Gloria Knolls Slide is at least 300,000 years old and 32 cubic km in volume, or 30 times the size of Uluru. The landslide could also have triggered a large tsunami, said the international team behind the find. The team made the discovery while conducting three-dimensional mapping of ancient reefs in the Queensland Trough, a vast basin adjoining the Great Barrier Reef.
