Abstract

Summary

Jumps of tilts, long-period oscillations and other geodynamic effects during catastrophic double earthquakes in Turkey on 02/06/2023 with M7.8 and M7.5 are being investigated with the data of tidal observations in Poltava. In the NS direction even at a distance over 1000 km during an earthquake a jump in tilts is clearly visible. Ultra-long-period waves with periods of 50–100 seconds and more were also detected. They appear in the records of both earthquakes and in all components of the seismic signal. The features of these and other geodynamic processes and their connection with the problem of earthquake forecasting are studied.
