July 21 - 365 - The Crete Earthquake and Alexandria Tsunami

On the morning of July 21, 365, people living all along the southeastern coast of the Mediterranean Sea saw a huge wave arising out of the ocean, which would then wash over Libya and the Nile Delta. The city of Alexandria saw massive property destruction and thousands of people perished. Caused by an earthquake near the island of Crete, the tsunami greatly effected the people living in the Roman Empire. Not even having a word for the phenomenon, Roman citizens saw it as a reflection of the political and religious turmoil upending Roman society.
