In Kamchatka, at the observation point <> with the help of a measuring systems based on a three-component piezoceramic seismic receiver monitoring of signals of seismoacoustic emission of near-surface sedimentary rocks. At the output of the measuring system, an oscillatory acceleration is recorded in the frequency range 0.5-400 Hz. The analysis is carried out on the basis of records of seismic acoustic signals from a group of regional earthquakes of 2019 with an energy class Ks > 10.0. The probability density distribution function of such a signal is not always is described by the normal distribution law, therefore, to study such stochastic time series are suitable methods of statistical physics, within the framework of which consider the properties of self-similarity of these signals.
