“…These and other pioneering studies have shown that earthquake faulting parameters, distribution and sense of motion on mapped active faults display close relationship between them (McKenzie, 1972(McKenzie, , 1978Le Pichon and Angelier, 1981;McKenzie and Jackson, 1983;Taymaz et al, 1991;Goldsworthy et al, 2002) but have not led to the formulation of a widely accepted kinematic model for the Aegean deformation. In the last 20 years GPS surveys have contributed to the quantification of the contemporary deformation of the Aegean region and provided important clues to the understanding of the large-scale kinematics (Billiris et al, 1991;Le Pichon et al, 1995;Davies et al, 1997: Clarke et al, 1998Briole et al, 2000;McClusky et al, 2000;Nyst & Thatcher, 2004). The westward extrusion of Anatolia continental block along the North Anatolian Fault, the NNEward subduction of the Eastern Mediterranean lithosphere beneath the Hellenic Arc, the subsequent SSW-NNE extension of the Aegean back-arc region, the collision of NW Greece with the Apulian block in the northern Ionian Sea north of the Kephallonia Fault and the incipient collision with the Libyan promontory south of Crete (Mascle et al, 1999) …”
