Altunel et al. (2009) dated Event E1 in Demirköprü Trench 1 to between 1801 and 1940 CE based on two radiocarbon samples located immediately above and below the Event E1 horizon. They suggested that Event E1 most likely corresponds to the 1872 CE Amik Gölü earthquake, although they noted that the 1822 CE Aleppo earthquake remains a viable alternative. Altunel et al. (2009) also proposed that Event E1 in Demirköprü Trench 2 correlates with the same seismic event identified in Trench 1. However, the absence of radiocarbon samples above the Trench 2 E1 horizon limited chronological precision, resulting in a constraint of no more specific than "after 1470 CE".
