Our professor in the Department of Geodesy, Prof. Ergintav, and our professors in the Department of Geophysics, Prof. Karabulut and Assoc. Prof. Dr. Konca, used continuous GNSS stations in Turkey to determine the deformation that occurred during the 2023 Mw7.8 Kahramanmaraş earthquake and found that the far-field displacements of the earthquake were higher than expected. The displacements expected to decrease to below 4-5 mm after approximately 400 km in standard elastic shear models were measured as around 10 mm even at a distance of 700 km. Moreover, the research team found that the direction of the displacement was not in the direction of the earthquake displacement field but in the direction of the plate motion. Although the exact source of this unexpected displacement field is unknown, Ergintav and his colleagues stated that the effects seen were due to long-term stress in the crust and that the Anatolian plate experienced the same displacement in 1 year during the Mw7.8 earthquake.
