The object of the study is the Palace of Culture of the polar branch of PJSC MMC Norilsk Nickel, located in Norilsk, where in recent years the thawing of the soils has a potential threat to the stability of engineering structures. The basic values of the frequencies of natural oscillations of the building were determined in August 2021 by the method of coherent reconstruction of the fields of standing waves and are 3.0, 3.7, 4.7 Hz on the short axis and 3.5 and 5.2 Hz on the long axis. The current (daily) frequency values are determined with an error of no more than 0.01 Hz from the amplitude spectra of seismic noise recordings (without active sources), which were obtained during continuous seismic monitoring from the end of August 2021 to the beginning of September 2022. From comparing the changes in the frequencies of natural oscillations with fluctuations in ambient temperature, it follows that during the year the frequencies change significantly (in winter their values are 11–12% higher than in summer), presumably due to defrosting/ freezing of the upper part of the soil. Against the background of this change, local fluctuations in frequency values were revealed due to cooling/ heating of the material of the building mainly at a positive ambient temperature (frequencies increase in direct proportion to temperature within 5–7%). According to the analysis of monitoring data after the annual cycle, the natural frequencies of the building in August 2021 and 2022 are not equal (the difference is up to 1.7%), which is presumably explained by the different depth of ground defrosting in the summer. To assess the impact of this phenomenon on the technical condition of the building, it is necessary to continue monitoring, first of all, to obtain data on changes in the natural frequ","PeriodicalId":52612,"journal":{"name":"Rossiiskii seismologicheskii zhurnal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135719878","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 neotectonic zoning and geodynamic conditions of its formation in the Southern and Middle Urals and adjacent platform territories were studied in connection with the Katav-Ivanovo mediummagnitude earthquake occurred in 2018. The epicenter was located outside the known zones of possible seismic sources, which required additional research to determine the causes of the earthquake. As a result of near-surface and deep research the Uraltau-Magnitogorsk and Osinsko-Bolsheusinskaya geodynamic systems have been established, which are the cause of the transverse segmentation of the Urals and, possibly, one of the factors of seismic activity. The geodynamic systems are inconsistently articulated with each other with the development of the Birsko-Karatau geodynamically active zone and the Katav-Satka interference zone. The earthquake is associated with the Katav-Satka interference zone. The interference zone has been investigated with respect to fracturing and slickenlines. Orientations of modern stresses induced from the active regions are estimated. Modern stresses are the reason for the activation of the Zilmerdak from the beginning of the Late Paleozoic overstep and, as a consequence, the Katav-Ivanov earthquake. Earthquakes caused the development of secondary dangerous seismogenic phenomena and deformation of buildings.","PeriodicalId":52612,"journal":{"name":"Rossiiskii seismologicheskii zhurnal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135720220","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}

This method can be successfully used in solving various practical problems. We have used it as an effective tool for a thorough analysis of noisy seismograms of regional explosions and earthquakes in order to select the optimal filtering frequency. The cut-off frequency selected with the help of fingerprints will allow you to design an optimal filter that not only reliably suppresses low-frequency noise, but also carefully preserves the signal it hides. Moreover, the method works well when the noise intensity exceeds the signal intensity many times over and under conditions of partial overlap of their frequency ranges. Fundamental is the initial orientation of the method towards automatic implementation with minimal use of additional information. In conclusion, this article proposes to use a neural network expert system that allows you to evaluate the quality of the fingerprint algorithm. To create such a system, we needed to explore current trends in seismology regarding the use of artificial neural networks. Based on extensive worldwide experience, it has been shown that there is a clear renewed interest in the use of small, lowcost networks. The principle on which they are based lies in their perception as training and input data of compact, complexly structured parameters of a high degree of transformation of primary seismograms. It is these parameters that include the characteristics taken from fingerprints using the algorithms we propose. So our experience in creating a neural network expert system naturally turned out to be successful. The reliability of the estimates obtained turned out to be very close to the practical limit of the fingerprint method.","PeriodicalId":52612,"journal":{"name":"Rossiiskii seismologicheskii zhurnal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135719879","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}
