Structural architecture of the Rhodes Basin: A deep depocentre that evolved since the Pliocene at the junction of Hellenic and Cyprus Arcs, eastern Mediterranean

Seismotectonic content by the source parameters of the 10 June 2012 Ölüdeniz-Fethiye (Dodecanese Islands) Mw 6.1 earthquake and aftershocks (southwestern Turkey)

“…On the other hand, the Esençay basin located in the southeast of Fethiye Gulf and the edge of the west limb of the Isparta angle was defined as forearc (Ten Veen 2004). Hall et al (2009) mapped the FBFZ left lateral strike slip fault with thrust component. The distribution of the stress states in the northeast of Fethiye Gulf varies with geologic age.…”

“…This situation is a result of the anticlockwise rotational movement of the region between the east and southeast of Fethiye Gulf (Kissel and Poisson 1986). Hall et al (2009) mapped the active faults as NE-SW thrust and sinistral strike slip, displayed in Fig. 1a, using the seismic reflection method in a region from approximately 20 km of southeast data set-A zone and 40 km east and southeast of Rhodes Island.…”

“…This postulation is supported by the slip vectors of two different events observed on the slip plane of Fethiye Mw 6.1 earthquake. Hall et al (2009) indicated that dominant compression around the southeast of the region could create small scale intraplate strike-slip faults. Additionally, the explicit strike-slip offset in the focal mechanism solutions of the Fethiye Mw 6.1 earthquake and its aftershocks may be developed by the rotational movement of the region (see Fig.…”

“…Some important bathymetric features in the region are the Pliny trench located 200 km south of the epicenter, the Strabo trench located 100 km southeast of the Pliny trench, and the Anaximander and Anaxagoras seamounts located in the southeast of the Rhodes Basin. The south border of the seamounts is associated with the Hellenic Arc (Hall et al 2009). …”

“…7 a Focal mechanism solutions according to the international seismological centers. Besides the focal mechanism solutions of the 10 June 2012 Fethiye Mw 6.1 earthquake main shock and after shocks, bathymetry and active faults are shown (thrust and fold axes from Hall et al 2009, faults located in Rhodes Island are adapted from Leite and Mascle 1982;Mascle and Martin 1990; normal faults between Rhodes Island and Fethiye Gulf are adapted based on the results of this study and from Hall et al 2014). The focal mechanism solutions for the earthquakes (M C 3.5) and others are plotted with blue and red beach balls respectively.…”
