The precursors of earthquakes that occurred on February 6, 2023 with an interval of nine hours in the southeast of Turkey are considered. The epicenter of the first, with a magnitude of 7.8 (± 0.1), was located in the Shehitkamil area in Gaziantep, the epicenter of the second, with a magnitude of 7.5 (± 0.1), was in the Ekinyozu area in Kahramanmarash. The approach used is related to the study of the change in the entropy of the measured fields, which occurs as a result of the activation of the processes of faults of lithospheric plates immediately before an earthquake. It was possible to reveal the phenomenon of processes with a high degree of determinism that occur before a seismic event. A change in the nature of the movement of stations of space geodesy and geodynamics of the CrAO for all coordinates was registered a few days before the start of the block of Turkish earthquakes, which indicates a change in the balance of forces in the region.
