Scientists find huge ancient landslide at Great Barrier Reef

Sydney: A massive underwater landslide that could have triggered a towering tsunami some 300,000 years ago has been discovered in the depths of Australia’s Great Barrier Reef, scientists said.

The ancient landslide, likely caused by a strong earthquake that could have generated a tsunami wave 27m-high, was discovered unexpectedly by researchers conducting three-dimensional mapping of the seafloor around the world’s biggest reef.
