(a) Generalized geological-tectonic map of the Kavala-Xanthi-Komotini and Maronia-Alexandroupolis fault zones (modified from Mountrakis and Tranos, 2004). Stereographic projections on the map show the main movements of the different segments, with 1, 2, 3, being the order from the youngest to the oldest movements. Pa: Paradisos; Si: Simantra; Ko: Koptero; Ias: Iasmos; Po: Polyanthos; MP: Mega Piston; Mi: Mischos; Ag: Agiasma; Ti: Tichiro; Gr: Gratini; Do: Dokos; Fi: Fillira; Sk: Skaloma; Ni: Nikites; Ki: Kinira.
(b) The contemporary stress regime, as defined by the latest normal movement along the Kavala-Xanthi-Komotini fault zone.
(c) Stereographic projection of the latest movement of the Maronia-Alexandroupolis Fault Zone and Avantas Fault.
(d) Focal mechanisms of the earthquakes closest to the fault zone. The latest movement of the fault zone fits that inferred from the focal mechanisms and indicates a NNE-SSW to NE-SW extension axis (T).
