Event E3 earthquake in the lbeyli Trench (aka Trench 6) Open this page in a new tab

Duman et al. (2020) report that Event E3 in the Elbeyli Trench (T6) is dated to approximately 1035–1215 CE ( calibrated radiocarbon age range) and suggest that it may correlate with the 1114/5 Mamistra and Marash earthquakes. Event E3 was identified from deformation associated with a wedge, or fissure fill, that formed between fault splays F3 and F5. Duman et al. (2020) report that "two samples of this fissure fill material were dated and yielded ages of AD 775 to 975, and AD 1035–1215." They interpret the approximately 250-year discrepancy between these samples as reflecting the incorporation of organic material of different ages that had been reworked prior to deposition within the fissure fill. On this basis, they infer the timing of Event E3 from the younger and presumably less reworked AD 1035–1215 sample. Fault motion associated with this event was described as normal dip-slip faulting. Duman et al. (2020) do not report recognizing a correlating expression of this event in any of the other Sürgü–Misis trenches.
