The tectonic map of Turkey includes the North Anatolian fault, East Anatolian fault, and Hellenic and Florence trenches. The westward movement of the Anatolian block results from (1) differences in rates of motion between the Arabian and African plates, (2) different directions of motion between the Anatolian block and Eurasian plate to the north, and (3) subduction of the African plate beneath the Anatolian block at the Hellenic and Florence trenches. The Arabian plate is moving to the north faster than the African plate, both relative to a stable Eurasian plate. The result is a westward moving wedge incorporating most of Turkey.
