An international team of scientists have discovered evidence of a massive ancient undersea landslide close to Great Barrier Reef in Australia.
The Gloria Knolls Slide, which could also have triggered a tsunami, occurred nearly 300,000 years ago. It was 32 cubic kilometers in volume, or nearly thirty times the size of Uluru, a rock landmark in central part of Australia.
The researchers discovered the ancient landslide while conducting 3-dimentional mapping of the Queensland Trough’s ancient reefs. The Queensland Trough is a big basin adjacent to the Great Barrier Reef.
