The Reflection of Geodynamic Processes in Local Geoacoustic Emissions

摘要

This paper is concerned with the correlation of fast local processes that generate geoacoustic emissions and the regional character of excitation in the geologic medium prior to large earthquakes. It is shown that this comparison is possible based on the unifying process of vertical energy transport due to the earth’s degassing.For the first time here, we examine local geoacoustic characteristics by analyzing Poincare diagrams and developing difference equations that describe dynamic changes in the characteristics of acoustic emission sources. Based on this concept, and incorporating the continuity of geoacoustic emissions, we suggest a decompressional model of seismoacoustic noise and geoacoustic emissions as a component of the noise.
