The 479 BC Potidaea tsunami is the oldest record of a paleotsunami in human history.[1] The tsunami is believed to have been triggered by a Ms 7.0 earthquake in the north Aegean Sea. The associated tsunami may have saved the colony of Potidaea from an invasion by Persians from the Achaemenid Empire.
