Greece is located in a complex geological boundry zone in the Eastern Mediterranean between the Eurasian and  African Plates.  The Northern part of Greece lies on the Eurasian Plate while the Southern part lies on the Aegean Sea Plate.  The Aegean Sea Plate is moving SouthWestwards with respect to the Eurasian Plate at about 30mm per year, while the African Plate is moving Northward, sliding beneath the Aegean Sea Plate at a rate of about 40mm per year.
