A 2023 earthquake sequence in southern Türkiye caused severe damage and resulted in over 65,000 deaths. The two main shocks, with magnitudes of Mw 7.8 and Mw 7.6, occurred on February 6, 2023, and propagated along the East Anatolian Fault Zone (EAFZ), the Dead Sea Fault (DSF), and the Cyprus Arc. High-resolution satellite imagery and field measurements were used to map the surface rupture and estimate the rupture width, total and on-fault offset, and diffuse deformation. The ruptures extended over 310 km and 140 km, with maximum offsets of 7.5 m and 8.7 m near the epicenters. The study identified three main segments for the Mw 7.8 rupture and three for the Mw 7.6 rupture, with varying offset and fault width. The diffuse deformation was found to be 58% for the Mw 7.8 rupture and 47% for the Mw 7.6 rupture. The study also examined the potential for supershear rupture, noting that while some areas showed characteristics of supershear, the overall rupture was not fully supershear. The results provide new insights into seismic hazard assessment and the complex fault geometry in the region.A 2023 earthquake sequence in southern Türkiye caused severe damage and resulted in over 65,000 deaths.
