Largest-Ever Undersea Landslide Revealed on Great Barrier Reef
Added Feb 15, 2017 | Rate View top rated
The largest underwater landslide, along the slope bordering the famous Great Barrier Reef, has been discovered by an international group of scientists. The ancient remains, known as the Gloria Knolls Slide, were discovered about 45 miles off the coast of Queensland, Australia. The researchers modeled a potential tsunami for a sudden undersea mass failure of this scale, yielding a wave elevation of about 85 feet. More seabed mapping and sampling is needed to determine the timing at which the submarine landslides occurred. "The oldest fossil corals recovered off the top of the knoll were 302,000 years old - which means the landslide event that caused these knolls must be older," says lead researcher Dr. Angel Puga-Bernabéu of the University of Granada. The research was a collaborative effort between James Cook University, University of Sydney, University of Granada, University of Edinburgh, and the Australian Nuclear Science and Technology Organization.
