| Abstract: | The results of experimental observations over variations of the Earth’s magnetic field recorded by the instruments of the North Caucasus Geophysical Observatory are presented. We observed specific ultralow-frequency quasi-oscillatory waveforms preceding strong distant seismic events in the structure of electromagnetic signals. |
