Abstract:

The East Anatolian Fault Zone (EAFZ) is a 700-km-long left-lateral transform fault system along the boundary between the Anatolian and Arabian plates. In the interseismic period, the eastern segments of the EAFZ display relatively uniform seismic activity, while the western segments exhibit seismic gaps, localized clusters and extensive diffuse zones. The nature of these relatively silent segments of the EAFZ has been revealed in detail based on the aftershock activity following the February 6, 2023, Mw7.8 Kahramanmaraş on the main branch and Mw7.6 Elbistan earthquakes on the northern. In this talk, considering the historical earthquakes and seismic potential, we will be reviewing the deformation of the EAFZ at timescales, from its preseismic deformation to postseismic aftershock activity.
