Huge "megabeds" from ancient supervolcano eruptions are hiding at the bottom of the Mediterranean Sea, researchers have found. Their discovery points to a cycle of catastrophic events that appear to hit the region every 10,000 to 15,000 years. 

Megabeds are huge submarine deposits that form in marine basins as a result of catastrophic events like volcanic eruptions.
