It is a
well-known phenomenon that the southern coast of Turkey
is sinking and this can easily be seen off the coast of Andriake
where tourists take tours in boats with a glass bottom to visit the remains of
the sunken city of nearby Kekova.
This is due to the fact the African platonic plate is pushing against and
sliding over the Asian plate.
In antiquity,
Phaselis was a privileged anchoring place since sailors could profit from the
sheltered Southern Harbor which is generally used by today’s tourists, or the Northern Harbor which was and is accessible under
all weather conditions, either by southwesterly and northeasterly winds. The Naval Harbor ,
in turn, was located deep inside the Northern
Harbor and clearly extremely
well protected. The harbor slowly silted up (see also: Phaselis and its three harbors).
The movement of the tectonic plates generates earthquakes which have hit the areas of Lycia and Pamphylia since antiquity. Especially catastrophic was the earthquake of 141 AD (well-documented because Opramoas of Rhodiapolis donated large sums for the reconstruction of more than thirty Lycian cities between Telmessus in the west and Phaselis in the east) and the one that occurred on the 5th of August 240 AD when the same cities were destroyed once again.
This means that Phaselis is only one such example, but the phenomenon is worth noticing when walking among the beautiful remains of these once so proud and prosperous cities!
