“…The highest value of S mf (low tectonic activity) is associated with segment 2, while the lowest values are for segments 4 and 3 (high tectonic activity), which indicates a straighter mountain front than the others. The highest degree of tectonic uplift occurs in segment 4 and this is consistent with the view of Yönlü et al (2013), who discussed the presence of the largest morphological offset of the EAF along the same segment.…”

“…Several fault-related basins, e.g., the Hazar and Gölbaşı basins, are present along segment 4. The Gölbaşı basin is the largest basin along the EAF (Yönlü et al, 2013). Yönlü et al (2013) examined the geology and geomorphology around the Gölbaşı basin and argued that there was a wide river valley in which the Aksu River flowed and was later blocked by a landslide at 31.6 ± 0.5 ka.…”

They concluded that as a result of this obstacle, the Aksu River changed its course and was left laterally offset by the EAF by ~16.5 ± 0.5 km.…”

“…The Kürk Delta is located at the south‐western extremity of Lake Hazar, which occupies a complex pull‐apart basin (Garcia Moreno et al ., ) along the central part of the East Anatolian Fault (EAF). The EAF is a major 600 km long continental strike‐slip fault located in eastern Turkey (Şaroğlu et al ., ; Duman & Emre, ; Yönlü et al ., ). It accommodates, together with the NAF, the westward extrusion of the Anatolian plate ( ca 21 mm year −1 ) away from the Arabia–Eurasia Collision Zone (Fig.…”

Earthquake imprints on a lacustrine deltaic system: The Kürk Delta along the East Anatolian Fault (Turkey)

Deltas contain sedimentary records that are not only indicative of water‐level changes, but also particularly sensitive to earthquake shaking typically resulting in soft‐sediment‐deformation structures. The Kürk lacustrine delta lies at the south‐western extremity of Lake Hazar in eastern Turkey and is adjacent to the seismogenic East Anatolian Fault, which has generated earthquakes of magnitude 7. This study re‐evaluates water‐level changes and earthquake shaking that have affected the Kürk Delta, combining geophysical data (seismic‐reflection profiles and side‐scan sonar), remote sensing images, historical data, onland outcrops and offshore coring. The history of water‐level changes provides a temporal framework for the depositional record. In addition to the common soft‐sediment deformation documented previously, onland outcrops reveal a record of deformation (fracturing, tilt and clastic dykes) linked to large earthquake‐induced liquefactions and lateral spreading. The recurrent liquefaction structures can be used to obtain a palaeoseismological record. Five event horizons were identified that could be linked to historical earthquakes occurring in the last 1000 years along the East Anatolian Fault. Sedimentary cores sampling the most recent subaqueous sedimentation revealed the occurrence of another type of earthquake indicator. Based on radionuclide dating (137Cs and 210Pb), two major sedimentary events were attributed to the ad 1874 to 1875 East Anatolian Fault earthquake sequence. Their sedimentological characteristics were determined by X‐ray imagery, X‐ray diffraction, loss‐on‐ignition, grain‐size distribution and geophysical measurements. The events are interpreted to be hyperpycnal deposits linked to post‐seismic sediment reworking of earthquake‐triggered landslides.

“…earthquake struck the town of Sivrice (Elazig, Turkey) located within the East Anatolian Fault (EAF) zone that formed the boundary between the Arabian and Anatolian plates [18]. Some reseachers reported that the last recorded large historical earthquake near the study area is the 1513 event, which involved surface faulting between Türkoğlu and Gölbaşı [19].…”

One of most prominent and active faults in Eastern Turkey is the NE-SW oriented left-lateral strike-slip East Anatolian Fault Zone (EAFZ) with a length of approximately 500 km. In this study, we have examined the recent seismicity of EAFZ that was obtained from the records of 34 three-dimensional broad-band earthquake stations established around the fault zone within TURDEP project since 2006. Further the seismicity and fault mechanism solutions of EAFZ, Eastern Turkey have been examined. The new fault mechanism solutions in addition to previously published 220 earthquakes, with a magnitude of ML=2.0 or more were determined by a local moment tensor solution and P-wave first motion data. It was suggested that the recent tectonic deformation of EAFZ south of Türkoğlu was taken up by the left-lateral strike-slip active faults in between Amik and Adana Basins were young trans-tensional stress regime was also active.
