Tectonic geomorphology of the Şemdinli Yüksekova fault zone (SYFZ) and Başkale fault zone (BFZ) (SE Turkey)

The collision between the Arabian and Eurasian plates resulted in the uplift of The East Anatolian Province of Shortening (EAPS). Within the EAPS, the faulting mechanism is characterized by right- and left-lateral strike-slip faults, thrust faults, and a relatively limited occurrence of normal fault...

Within the EAPS, the faulting mechanism is characterized by right- and left-lateral strike-slip faults, thrust faults, and a relatively limited occurrence of normal faults. When examined on a regional tectonic scale, about 70% of the deformation of the EAPS is controlled by strike-slip faults.

These fault zones are the Şemdinli Yüksekova Fault Zone (ŞYFZ), which exhibits right lateral deformation and is defined as a seismic gap, and the Başkale Fault Zone (BFZ), which has a left lateral deformation and that caused a destructive earthquake in (23/02/2020 ,Mw:5.9).

description The collision between the Arabian and Eurasian plates resulted in the uplift of The East Anatolian Province of Shortening (EAPS). Within the EAPS, the faulting mechanism is characterized by right- and left-lateral strike-slip faults, thrust faults, and a relatively limited occurrence of normal faults. When examined on a regional tectonic scale, about 70% of the deformation of the EAPS is controlled by strike-slip faults. However, the proportion of right- and left-lateral strike-slip faults contributing to this deformation remains unknown and is poorly understood.
