What is the history of tsunamis in ancient Greece?

Ancient Greece experienced notable tsunamis that destroyed armies and coastal settlements, prompting early historical inquiry into their origins. While writers like Herodotus originally attributed these giant waves to divine wrath, the historian Thucydides correctly deduced in the fifth century BC that they were caused by ocean earthquakes. Records include events affecting Potidaea in 479 BC and the Malian and Euboean Gulfs in 426 BC.
