A recent study suggests that the Mediterranean Sea was resupplied by an immense flood, known as the Zanclean Megaflood, around 5.3 million years ago.
The flood, which followed a period of desiccation called the Messinian Salinity Crisis, challenges the belief that the sea gradually refilled over 10,000 years.
Researchers found evidence of the megaflood in geological features in Southeast Sicily, including streamlined ridges and a 'W-shaped channel' connecting to the Noto Canyon.
Computer models revealed that the Zanclean Megaflood had unprecedented flow rates and reshaped the landscape, providing insights into Earth's geological history.
