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.","PeriodicalId":45174,"journal":{"name":"Seismic Instruments","volume":"62 1","pages":"38 - 48"},"PeriodicalIF":0.3,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147827006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Detailed paleoseismological studies have been carried out to study unconsolidated sediments and soils in the zone of an active fault structure: the Chuna seismic dislocation. New evidence of Late Pleistocene–Holocene earthquake traces has been found in Quaternary sediments and lacustrine sediments. Based on a combination of methods—isotopic (14C), luminescence (IR-OSL), geomorphological, and correlation—a previously unknown sequence of five events was established: 11.6 ± 0.5, 9.1 ± 0.2, 8.3 ± 0.2, 6.5 ± 0.4, and 2.45 ± 0.35 ka BP (calibrated). It reflects multiple noncoeval activations of the fault and seismic events that occurred in the central Kola Region throughout the Late Glacial and during the Holocene. This made it possible to significantly organize earlier existing information about the timing of paleoearthquakes in the central Kola Region. The results of the study significantly expand and complement paleoseismic catalogs. They reveal new evidence of prehistoric earthquakes in the region and are aimed at reducing the risks of natural destructive processes.","PeriodicalId":45174,"journal":{"name":"Seismic Instruments","volume":"62 1","pages":"19 - 37"},"PeriodicalIF":0.3,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147827002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A distinctive feature of the experimental setup used is the extended movable block, which allows for a significant increase in the area of interblock contact filled with dry fine-grained sand. This made it possible to study the spatial pattern of the development of zones of active deformation of the contact zone by solving the problem of locating acoustic emission sources. Particular attention is paid to the response of the contact zone to water injection into it and the direct effect of electric current. As a result of the experimental studies, the spatiotemporal patterns of the response of the model fault to an increase in shear load and fluid and electric effects were determined. It is shown that the effect of electric current causes an increase in acoustic emission activity in the entire area between the electrodes, with the exception of the area of emission activation at the water injection stage. It has been established that electric action can initiate dynamic movement with the activation of spatial areas manifested in the previous stages of action.","PeriodicalId":45174,"journal":{"name":"Seismic Instruments","volume":"62 1","pages":"49 - 57"},"PeriodicalIF":0.3,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147827003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The method makes it possible, using the obtained theoretical formulas, to calculate the values of all three ground movement parameters—displacements, velocities, and accelerations—during strong earthquakes with magnitudes of M ≥ 6.0 for general inhomogeneous (multilayer) soil foundations. The article considers cases of inhomogeneous two-layer foundations. The results obtained for 16 variants of heterogeneous two-layer construction sites of categories I–IV based on seismic properties with magnitude M = 7.0 and distance of 15 km from the line of rupture of the predicted earthquake are given as an example. Comparison of the results obtained for real heterogeneous foundations with equivalent homogeneous foundations showed up to 1.3–1.6 times of discrepancies towards an increase, depending on the number of five or three modes of higher oscillations taken into account. Significant influences of various modes of natural oscillations of foundations on the values of displacements and accelerations on the ground surface of a heterogeneous foundations compared to a homogeneous foundation have been revealed. A significant decrease (two or more times) in the rigidity of the upper layer, compared to the rigidity of the lower layer, leads to a significant increase in accelerations on the ground surface. It is recommended that for heterogeneous foundations, the predicted values of displacements and accelerations should be implemented taking into account at least five modes of oscillations of the soil foundation.","PeriodicalId":45174,"journal":{"name":"Seismic Instruments","volume":"61 6","pages":"486 - 504"},"PeriodicalIF":0.3,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147579288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
