A team from Bristol University concludes that 60,000 years ago there was a giant earthquake under the sea. As a consequence of the detachment, there was the greatest flow of sand and mud ever measured on Earth: the mass that moved was ten times greater than it moves in a year adding all the rivers of the Earth. As a fact, they claim that the flow reached 150 kilometers wide and that, in addition, the mass traveled about 1,500 kilometers to its deposition.
