QUESTIONS OF THE METHODOLOGY FOR DETECTING SEISMIC ACTIVITY OF CONCENTRIC STRUCTURES

The relevance of the topic is determined by the development of the spatial distribution of earthquake foci in various morphogenetic types of concentric structures (CS) and is due to the need to study the structure of the earth's crust and upper mantle in Uzbekistan. Our Republic is one of the highly seismic regions of Central Asia, characterized by a complex geological and tectonic structure.
Until now, seismicity and seismic activity of the territory of Uzbekistan have been studied using geological, geomorphological, geophysical and seismological methods. On the basis of the obtained geological and geophysical results, seismic zoning and prediction of earthquake sites were performed. At the same time, the relationship of earthquake foci with concentric structures (CS) and geodynamic characteristics of the latter were not considered. Cosmophoto-geological information for the identification of lineaments and concentric structures, their analysis, connection with the seismic activity of the territory of Uzbekistan has not been widely used. Therefore, there was a need for a more detailed study of CS and their relationship to seismicity. The geological and tectonic structure of the regions is studied by various geological and geophysical methods. Recently, a remote method has been introduced into the practice of studying the structure and geodynamics of the earth's crust.
