btw, the stuff about the black sea rising up over bulgaria, the eastern region of the country is full of sandstone, there's even one place i saw while travelling on the train to Varna that they had cut the top off a whole giant mountain made out of it, and one of the biggest lime factories in europe is in a town called Devnya and the size of the cable cars and the train station where it was loaded on was epic, i mean, epic... the factory was pretty damn huge too, several really big smoke stacks for the giant furnaces and shit... probably a big part of what glued most of eastern europe's commieblocks came from this place (i'd guess russia has some good ones of its own)... but massive sandstone deposits are clearly from the sea, sand and fragments of shells and diatoms and other bony microorganisms, coral, etc, animals that absorb the calcium from the water and use it to build their skeletons and other things (all shells, etc)

because it was bulgaria, that indicates that the initial shift was towards bulgaria, the sea rose up over the regions around the caspian and then as it al piled up over that peninsula and across the other side it then sloshed back

so, based on that i'd say that when this event happened the direction of the shift was east-northeast at that time, as the sloshback is more violent and rather than just flowing up, the whole seabed of the black sea would have been washed up onto the land
