If those underwater cities had expensive objects still in the ruins, wouldn’t it mean that the inundation by water was fast. Otherwise the people would have taken the stuff away before the complete flooding.
So they had rapid climate change, I guess. Even in those times..

Yes, the SUV tire tracks and the plastic straws and fast food drink lids show they were on a downward earth stewardship trend at the end.
This port flourished at the mouth of the Nile in the seventh century BC. The port city was also known as Thonis to the Egyptians and Heracleion to the Greeks. It flourished as a vital center for trade and culture, and then disappeared when it was suddenly flooded.
At the end of the second century BC and possibly after a severe flood, the land on which the central island of Heracleion was built underwent soil liquefaction, solid clay quickly turned into liquid and buildings collapsed in the water. A small number of residents remained in the Roman era and the beginning of the Arab conquest, but by the end of the eighth century AD, what remained of Thonis sank under water.
