## 4 Conclusions  
On 4 March 2024, an \(M6.1\) earthquake (\(N\) 42.93\({}^{\circ}\), \(E\) 76.96\({}^{\circ}\)) occurred, with the epicenter at a distance of 12.2 km only from the complex of measuring equipment of the Geophysical Observatory. In the Almaty city, 30 km from the epicenter, this earthquake was felt with an intensity of 5-6 points on the MSK-64 scale. In preparation for this seismic event, we detected in real time, 8 days before the main shock, when a characteristic cove-like depression appeared in the gamma-ray flux measured at a depth of 100 m, which effect indicated an approaching earthquake with high probability. A decrease (or sometimes increase) in the intensity of gamma rays underground is determined by peculiarities of the emanation dynamics of radon and radioactive products of its decay, which serves as an indicator of change in the stress-strain state of rocks during the activation of the seismic process. With regard to attention paid to ULF/VLF signals as potential precursors of earthquakes, an analysis was performed of the intensity of ENPEMF at the very low frequencies \(f=7.5\) kHz and \(f=10.0\) kHz and of the ULF waves in the band of 0.001-3 Hz. In order to study the possibility of disturbance transmission from the lithosphere to the ionosphere, the monitoring data on the DFS of ionospheric signal were involved in consideration. Summarizing the results of the present study, the following may be concluded:  
1. Seismogenic disturbances were detected among the ENPEMF signals registered at the frequency \(f=7.5\) kHz when the ferrite antenna of the recorder was directed toward the epicenter of the earthquake. An amplitude decrease of the ENPEMF background variation with violation of the characteristic diurnal rhythm was revealed 13 days before the main shock, succeeded by a distinct, five times above the background level, burst, which occurred 2 days before the shock. 2. It was shown that the \(G1\) class geomagnetic storm on 3 March 2024 had no impact on the intensity of ENPEMF. This was determined through simultaneous monitoring of the

An anomalous ULF signal was registered in the variation of the horizontal component of the Earth's magnetic field by an IMS-008 inductive magnetic sensor when the sensor was oriented in the direction of the epicenter. Noticeable magnification in the amplitude of the dynamic ULF spectrum, surpassing the background level by more than 2 nT, preceded the main shock by 18.23 min. 4. A prolonged cove-like disturbance appeared 8 days before the main shock in the variation of the DFS of the ionospheric signal. 5. It was revealed a sequence of disturbance appearance, first in the variations of the ENPEMF at very low frequencies and of the gamma ray background at rock depth, which reflect the activation dynamic of tectonic processes in the lithosphere, next in the DFS of ionospheric signal. 6. Transmission of the perturbation of seismogenic nature from the lithosphere up to the heights of the ionosphere, as detected by the Doppler ionosonde, can be explained by the concept of lithosphere-ionosphere coupling [27; 28]. According to the concept, this process may have originated from a change in ionization of the atmospheric boundary layer, caused, in turn, by the exhalation of radioactive gases onto the surface. 7. Observed simultaneity in appearance before the earthquake of the anomalies in various geophysical fields enhances the confidence in the connection of each particular effect with the preparation process of this seismic event.
