Tectonic setting of the Aegean (Papazachos et al. 1998)

Seismicity of the Eastern Mediterranean region showing quakes during 1973–2007 with magnitudes for M3 and larger. The relatively seismic inactive zone of the Cyclades is seen clearly. (Taymaz et al. 2007)

La mer Égée et ses environs (y compris la Turquie des Balkans et de l'ouest) sont les régions plus sismiquement actives de la Méditerranée ensemble et dans l'ensemble de l'Eurasie West. La raison est que cette région est parmi la plus stressée partie de la zone de collision entre les plaques tectoniques africaines et de l'Eurasie.
The island of Crete represents an uplifting sedimentary fore-arc zone located north of the subduction zone in the transition between the African and Eurasian plates.
The Hellenic arc parallels the subduction zone at a distance of about 120 km to the north, and contains several active volcanic centers (Methana, Santorini, Nisyros, the Bodrum Peninsula).
The Cretan Trough is a depression between Crete subject reaching a depth of about 2000 m.
The most interesting feature of the northern Aegean is the northern Aegean trough, which reaches depths to about 1500 m. Its extension to the NE includes probably the small depressions of the Marmara Sea.
