Event V from Tevekkelli Trench Open this page in a new tab

At the Tevekkelli Trench, excavated across the southwestern part of the Pazarcık segment of the East Anatolian Fault, Yönlü and Karabacak (2023:5-6) identified Event V as an older surface rupture in Tevekkelli T1, predating the beginning of unit h and following deposition of unit f. The trench exposed a prominent shear zone made of pervasively sheared plastic clay gouge, with shear fabrics and faulted blocks indicating dominant strike-slip movement.

A radiocarbon sample from unit h, which postdates Event V, produced a calibrated age of 3321–2871 BCE ( ), while a sample from unit f, which predates Event V, produced a calibrated age of 5961–5631 BCE (2σ). These two samples therefore constrain Event V to between 5961 and 2871 BCE (2σ) but also after Event U in the Tevekkelli Trench.

Yönlü and Karabacak (2023:6) note that more events could be expected between Event V and Event X, but that evidence for these intervening events could not be identified, probably because later surface ruptures overwrote earlier fault strands within the same narrow fault zone.
