  • $\begingroup$ "Over the course of less than a year, you could see the sea level drop by about 6 meters": Why would you? The Black Sea was not empty, it was a large freshwater lake, and the Mediterranean was connected to the global ocean. Even according to the wildest variant of the Black Sea Deluge Hypothesis, the pre-flood level of the Black Sea was not more than 80 meters below the level of the ocean. The Black Sea is only about 1/900 of the area of the ocean, so that filling the Black Sea by 80 meters of water would decrease the level of the ocean by not more than 10 cm (4 inches). $\endgroup$ Commented Jul 19, 2022 at 21:50

    $\begingroup$ @AlexP : the answer uses the Black Sea deluge as an example, to have something similar in the fictional world, and not necessarily a 1-to-1 exact replica. $\endgroup$ Commented Jul 20, 2022 at 5:00

    $\begingroup$ Or, if you want to sink something, look at the Zanclean flood hypothesis, in which (in some interpretations) the Mediterranean basin filled in over the course of 1-2 years after a catastrophic breach of a natural dam at the Strait of Gibraltar. $\endgroup$ Commented Jul 20, 2022 at 8:39
