German geologists believe a tsunami recorded by the ancient historian Herodotus did indeed protect a Greek village from Persian invaders. They say they have found evidence in northern Greece that the event in 479 BC saved the village of Potidaea. Herodotus recorded that huge waves had killed hundreds of Persian soldiers during the siege of the village.
