Complexities of the Turkey-Syria doublet earthquake sequence
Seismo-tectonics of the 2023 earthquake sequence along with seismological and geodetic observations
In the early morning of February 6th, 2023, an M7.8 earthquake occurred in southeastern Türkiye near the northern border of Syria. The event initiated a complex sequence of aftershocks, including an M7.6 earthquake about 9 h later and 90 km to the north (Figures 1A and 1B). The earthquake sequence is also referred to as a strong doublet earthquake sequence. Aftershocks of the two strong earthquakes occurred along two separate branches of the East Anatolia Fault, with lengths of up to 300 km, and some aftershocks occurred in Syria (NEIC/USGS, 2023).
