The Pütürge segment of the East Anatolian Fault (EAF) represents a critical link in the tectonic framework of the region. The northeastern end of this segment ruptured during the 2020 Sivrice earthquake (Mw 6.8), while the southwestern end marked the termination of the 2023 Kahramanmaraş earthquakes (Mw 7.7, Mw 7.6). Between these two events, the segment remained a notable seismic gap until the Mw 6.0 earthquake on October 16, 2024.
This study utilizes GNSS and InSAR data to examine the deformation dynamics of the Pütürge segment before and after the 2024 earthquake. While the extent of rupture during the October event remains unclear, preliminary geodetic analyses provide valuable insights into strain accumulation, potential creep activity, and coseismic deformation patterns.
Our findings contribute to understanding the seismic behavior of the Pütürge segment, emphasizing its importance in seismic hazard assessments and the broader tectonic setting of the East Anatolian Fault.
