On the Relation Between Geophysical Signal Anomalies and Earthquakes

The presented work examines the pre-seismic anomalies of the geoacoustic emission signals recorded in Kamchatka in 2017-2019. The authors formulated signs of geoacoustic emission anomalies and features of their occurrence. On the basis of these features, a sample of the geoacoustic signal anomalies recorded in 2017-2019. Also, a sample of earthquakes occurred during the same time period was formed. To search for hidden patterns in the samples, the methods of searching for sequences and association rules were used. The probability of occurrence of the geoacoustic emission pre-seismic anomalies is estimated.
