There were two major earthquakes on the Eastern Anatolian Fault (EAF) and its segments on February 6, 2023,
with magnitudes of Mw: 7.7 (Pazarcık) and Mw: 7.6 (Elbistan). There was another earthquake with a
magnitude of Mw: 6.3 (Samandağ) on February 20, 2023. There have been many devastating earthquakes in the
region throughout the historical and instrumental period. During these earthquakes have seen important left
lateral displacements on the fault segments along the EAF. The distribution of the February 6 earthquakes and
the aftershocks clearly revealed the broken fault segments (Pazarcık, Erkenek, Amanos, Çardak) in the region.
Within the scope of the study, significant displacements were measured on fault segments that broke during
earthquakes. The data obtained in the field and the focal mechanism solutions of the earthquakes show that, as
a result of the collision of the Eurasian and Arabian Plates in this region, a compressional tectonic regime in
approximately N-S direction is still active today and this tectonic regime result in a transtensional character.
These earthquakes showed that the Arabian Plate, separated from the African Plate, moved to the north and the
Anatolian Plate (block) moved to the west
