The Africa plate subducts beneath the Aegean Sea plate along the Hellenic arc, from the western Peloponnesus through Crete and Rhodes to western Turkey, at a rate of almost 40 mm/year.
Shallow-focus earthquakes (focal depths less than 50 km) occur on faults in the boundary-region of the two plates. From Crete to the west and northwest, most shallow earthquakes near the Hellenic-arc plate boundary are produced as the result of reverse or strike-slip motion
The Anatolian plate moves with a velocity of 25mm/y towards west.
The Aegean plate moves with a velocity of 45mm/y towards southwest.
