### Interactions Prior to the Seismic Event
The signal on channel 4 was positively correlated with the signals from probes 2, 3, 5, and 6 prior to event no. 4 and negatively correlated prior to events no. 2 and 3 (Figure 23A). Figure 22: (**A**) Comparison of the correlations between radon signals recorded by the probes and signals of tectonic activity in the rock mass observed on individual channels from 49 to 72 h before four seismic events, excluding correlation coefficients at a statistically insignificant level, i.e., <0.4. Correlation indicated with red line. (**B**) Comparison of the correlations between radon signals recorded by the probes and signals of tectonic activity in the rock mass observed on individual channels from 49 to 72 h after four seismic events, excluding correlation coefficients at a statistically insignificant level, i.e., <0.4. Correlation indicated with red line. Figure 23: **(A)** Comparison of the correlations between radon signals recorded by the probes and signals of tectonic activity in the rock mass observed on individual channels from 73 to 96 h before four seismic events, excluding correlation coefficients at a statistically insignificant level, i.e., \(<\)0.4. Correlation indicated with red line. (**B**) Comparison of the correlations between radon signals recorded by the probes and signals of tectonic activity in the rock mass observed on individual channels from 73 to 96 h after four seismic events, excluding correlation coefficients at a statistically insignificant level, i.e., \(<\)0.4. Correlation indicated with red line. The interactions between the signals from the radon probes and the tectonic activity channels 97-120 h prior to the seismic events were analyzed based on 879 data points, representing 45.8% of the input dataset. Of this set, 24.5% were positively correlated, and 21.3% were negatively correlated. For the period of 97 to 120 h prior to the events, only positive correlations were observed between the signal from probe 3 and the signal on channel 2, and between the signal from probe 6 and the signal on channel 3. In the first case, such a correlation was observed for 24 h, and in the second case, for 10 h. Solely negative correlations were observed between the signals from probes 4 and 5 and the signal from channel 3, and between the signal on channel 4 and the signal from probe 6. The correlation between the signals from probe 4 and channel 3 continued for only 12 h. Two negative correlations were observed at 24 h. The signal from channel 2 was positively correlated with the signals from probes 2 and 4 prior to events no. 2 and 4, and negatively correlated prior to event no. 2. The signal from channel 4 was positively correlated with the signals from probes 2, 3, and 5 prior to events 1 and 4. In contrast, the correlation was negative prior to events 2 and 3 (Figure 24A). The coefficients of the interactions observed between 121 and 144 h prior to the seismic events were analyzed based on 55% of the input dataset. Only positive correlations were observed between the signals from channels 1 and 2 and the signals from probes 5 and 4, respectively. The correlations continued similarly for 24 h. Only the signals from probes 3 and channel 3 were negatively correlated The 426 data showed negative correlations, and the 630 data showed positive correlations. Between 121 and 144 h, the correlations were positive for signals from channels 2, 3, and 4 prior to events no. 1, 3, and 4. Negative correlations were observed prior to event no. 2 (Figure 25A). The signal on channel 2 was positively correlated with the signals from probes 2, 5, and 6. The signal from channel 3 was positively correlated with the signal from Probe 4, and the signal from channel 4 was correlated with the signals from Probes 2, 3, and 5 (Figure 25A). The correlations recorded between 145 and 168 h prior to the seismic events were analyzed based on 794 data points, representing 41.3% of the input dataset. Of the set, 16.6% (319 data) represented negative correlations, and 24.7% (475 data) represented positive correlations.
