… [R]eported crustal warping in Anatolia (Turkey), as indicated by three measured curves of relative sea level rise at various points on the Black sea coast. The curves indicate dissimilar sea level variations starting sometime around 2300 BC at the three locations.1 The investigator, Nevessky, ascribes the vertical differences between curves by “particular neotectonic movements which occurred in different parts of the Black Sea shelf”. Again, the crustal movement can be linked to earthquake activity and the disastrous end of settlements in that region. Interestingly, evidence of the crustal warpings is supported by a recent core analysis of the Colchis lowlands, just east of the Black Sea border. Low amplitude differential movements associated with subsidence are reported by Bogolyubova to have occurred at around 2000 BC.2

An abrupt lowering of sea level at the Sea of Marmara in northwest Anatolia, no doubt related to the Black Sea warping occurred at this time. The investigators, Leroy, Kazanci, Ileri, Kibar, Emre, McGee and Griffiths make the statement, “This oscillation is most likely of regional extension and linked to tectonic movements in the area of the Sea of Marmara and the Black Sea.” A sudden upward shift of 1 meter is also reported by Pirazolli for the northernmost part of the eastern coast of the island of Rhodes at 2300 BC.3 Rhodes is located just off the southwest coast of Turkey.4
