ABSTRACT
Fethiye, Dead Sea is located tectonically quite complicated region affected by Aegean extensional regime, northward movement of African plate, subduction zones of Hellenic and Cyprus arc, Plini and Strabo fault zone, Rodos basin and Fethiye Fault zone in the southwest of Turkey. High seismic activity in the region is a result of this complex tectonic feature. The earthquake occurred on June 10, 2012; 12:44:16 (GMT), Mw=6.0, depth=29km is the last largest earthquake in the region. More than 100 aftershocks were announced within 15 days following the main shock by Bogazici University Kandilli Observatory and Earthquake Research Institute National Earthquake Monitoring Center (KOERI-NEMC).
In this study, focal mechanism solution of the main shock and the earthquakes greater than 4.0 (totally 8) has been obtained by P wave first motion method and moment tensor inversion. According to the results, fault mechanism of the main shock (Strike=293o, Dip=90o, Rake=-150o) is mostly left lateral strike slip with small normal faulting. While investigating the tectonic structure of the region with the both fault mechanism solutions of the main shock and the aftershocks, the normal fault components are in correlation with Rodos Basin and the strike slip mechanisms are conformable with Plini and Strabo Fault Zone.High resolution seismic reflection studies and monitoring micro seismic activity by supporting the seismic network in the region with ocean bottom seismometers should be done for identifying the active tectonism of region more clearly. It makes the studies more reliable.
