Mediterranean megaflood carved out hills in Sicily, study reveals
Rock deposits provide first land-based evidence of Earth’s largest flood, when water surged through strait of Gibraltar The event that refilled the Mediterranean basin 5m years ago is thought to have been the largest flood in Earth’s history, with water surging through the present-day strait of Gibraltar 1,000 times faster than the Amazon River, filling the basin in just a couple of years. Now jumbled rock deposits on the top of hills in south-east Sicily provide the first land-based evidence for this flood.The megaflood theory emerged in 2009, when scientists discovered a massive eroded channel at the bottom of the strait of Gibraltar. Subsequent research has revealed scours on the sea floor, showing how the water forced its way through the shallow gap between Sicily and mainland Africa, to fill the eastern Mediterranean Sea.
