Search for Anomalies of Group Behavior of Geoacoustic Emission Signal Pulse Flux

Long-term practice in the observation of geoacoustic emission (GAE) signals in the near-surface layer of the Earth shows their relation with plastic deformation processes occurring under seismic phenomenon impact. Acquiring of knowledge on such processes, based on information extraction from GAE signals, gives us the possibility to investigate the nature of catastrophic phenomena, caused by lithospheric plate movement, on the level of Kamchatka region. Extraction of useful information from GAE signals faces the difficulties associated with external natural factor effect on signal characteristics. These factors, just like seismic processes, have nonlinear character. We suggest a method allowing one to investigate seismic processes at the background of external factor effect. Some examples show the key possibility to distinguish visually the anomalous behavior of GAE signal parameter distribution on three-dimensional graphs.
