The paper «On analysis of signals of seismic acoustic emission of surface sedimentary rocks in Kamchatka» has been published
In Kamchatka, at the observation point “Karymshina”, using a measuring system based on a three-component piezoceramic seismic receiver, the signals of seismoacoustic emission of near-surface sedimentary rocks are monitored. At the output of the measuring system, an oscillatory acceleration is recorded in the frequency range of 0.5-400 Hz. The analysis is based on records of seismoacoustic signals from several regional earthquakes in 2019 with an energy class of Ks > 10:0. The probability density distribution function of such a signal is not always described by the normal distribution law; therefore, statistical physics methods are suitable for studying such stochastic time series, within which the properties of self-similarity of these signals are considered.
