Abstract <p>According to the stick-slip model, the relative movement of the fault faces is an act of unstable slip, in which movement begins after the stresses tangential to the fault plane reach a certain limit. The physical mechanism of dynamic slip along a fault consists of the sequential formation of conglomerates of loaded particles (force chains) in the contact zone and their subsequent destruction. These chains together form a power skeleton, characterized by a certain spatial structure and strength characteristics. An increase in shear stress on the fault banks leads to localized destruction of the power skeleton; further evolution of the system takes the destruction processes to higher spatial levels, which ultimately leads to a shift in the fault banks. Since the development of the process of destruction of force chains in the contact zone of a fault along the hierarchy of scales from bottom to top is similar to the development of fracture formation in a loaded medium from the micro- to the macroscale (sample scale), the authors put forward a hypothesis about the coherent behavior of acoustic noise accompanying the preparation of dynamic slippage and recorded in different areas of the fault zone. This study is tests this hypothesis on a laboratory scale using a setup simulating fault movement. As a result of the analysis, the hypothesis about the synchronization of the statistical properties of acoustic emission during the preparation and implementation of dynamic movement was confirmed. It is shown that the observation (detection) of the synchronization effect of the statistical properties of acoustic emission depends both on the set of parameters for which the spectral measure of coherence is calculated and on the location of recording of the initial data.</p>
