John of Ephesus provided lots of details and an inaccurate date for the
event (558–559 CE). He reported that a severe earthquake struck
and Beirut collapsed, together with many coastal cities
and villages in Galilee, Arabia, Palestine, and Samaria. He
added that along the entire Phoenician coast the sea withdrew
and retreated nearly two miles. When the earthquake came, the
sea pulled back from Beirut and other coastal cities of
Phoenicia for a distance of almost two miles. Then a tremendous
surge rushed back to its original level, and as the sea rose
behind the people of Beirut, "the earthquake brought down the city before them".
