### Interactions After the Seismic Event
The correlations were observed for the longest time on channels 3 and 4, from 12 to 24 h (Figure 25B). Between 145 and 168 h after the seismic events, statistically significant correlations were found for 784 data points, i.e., for 40.6% of the input data. They showed solely positive correlations between the signals from probes 2, 5,  
on channel 4 and the signal from probe 2. In each of these cases, the negative correlations continued for periods from 153 to 168 h, 145 to 160 h, 145 to 149 h, and 1 to 24 h, respectively. Except for the above-mentioned solely positive or negative correlations, the remaining relationships were mixed. The correlation time was the longest for channel 4. Between 145 and 168 h, identical correlations were observed after events no. 1, 2, and 4. Correlations were observed between the signal from probe 3 and the signal from channel 2, and between the signals from probes 3 and 5 and the signal from channel 4. After seismic events nos. 1 and 2, the correlations were negative, and after seismic event no. 4, they were positive (Figure 26B). The signals from the probes were both positively and negatively correlated with the signals from the channels over the entire observation period. These correlations occur in alternative order and have various durations (from several up to 24 h) in each 24-h interval block. Solely positive interactions for the probe-tiltmeter system were observed more frequently both before and after the seismic events. The only exception here is the interactions of the signal on channel 1, which is not positively correlated with any of the probe signals between 49 and 72 h after the event (Table 4). Solely negative correlations were observed in all interval blocks after the seismic events. However, they were observed only for the first 145 h prior to the events. At certain time intervals, some of the signals from the probe-tiltmeter system were observed to have both proportional and inversely proportional correlations, both before and after the seismic events. A proportional correlation between the signals from the probes and the signals from the seismic activity channels before and after the event was observed between 1 and 24 h. In both cases, the signal from channel 3 was positively correlated with the signals from probes 5 and 6. Additionally, the interactions frequently involve the same channels but with different probes. Between 1 and 24 h prior to the event, the signal on channel 4 was positively correlated with the signals from both probes 3 and 6, and after the event, only with the signal from probe 3. Between 25 and 48 h, positive correlations were observed between the probe and channel signals before and after the event. In the first case, the signal on channel 3 was positively correlated with the signals from probes 2, 3, and 5, and the signal from channel 4 was positively correlated with the signal from probe 6. However, after the event, the correlations are maintained between the signals from channel 3 and probe 2, as well as between the signals from channel 4 and probes 2 and 4. Between 49 and 72 h before and after the event, similarities were observed in both positive and negative correlations. Prior to the event, the signal from channel 3 was positively correlated with the signals from probes 3 and 5, and after the event, with signals from probes 3, 5, and 4. The only negative correlation before the event was between the signals from Channels 2 and Probes 2 and 6. However, after the event, the correlation was only observed with the signal from probe 6. Between 73 and 96 h, both before and after the event, no similarities in the correlations were observed. From 97 to 120 h, the signal from Channel 2 correlated positively, and the signal from Channel 3 correlated negatively with the probe signals both before and after the event. Between 121 and 144 h before and after the event, only positive correlations were observed between the signal on channel 2 and probe 3.
