Turkey is a seismically active region including the major Northern Anatolia Fault (NAF), where the Anatolian and Eurasian plates meet. The NAF, a strike-slip fault formed as the Anatolian plate is being pushed northwestwards by the Arabian plate, and has produced devastating earthquakes throughout the history. The Anatolian Plate's movement into the West towards Greece also produces significant earthquakes in the Aegean Sea and western Turkey.
