I am curious about what flooded it. Surely the sea level didn't increase by 45m in that short amount of time.

- pjc50 7y agoIt looks like the sea level for the northern side of the Mediterranean increased by about 1.5 meters since Roman times, due to isostatic rebound: http://people.rses.anu.edu.au/lambeck_k/pdf/242.pdf http://people.rses.anu.edu.au/lambeck_k/pdf/242.pdf The wikipedia page for Heracleion attributes it to "soil liquefaction", i.e. the whole city's underlying soft soil/sand became fluid enough to wash away. It must have been eroded to other parts of the sea, leaving the inerodible stoneworks lying there.
