The lost city of Helike
In 373 BC, a catastrophic earthquake and tsunami destroyed and submerged the ancient Greek city of Helike, on the southwest shore of the Gulf of Corinth. The sunken city gradually silted over until it disappeared without a trace. Ancient writers ascribed the disaster to the wrath of Poseidon, god of earthquakes and the sea.
