Resumo
The structural features of the Katav-Yuryuzan fault zone are considered. Based on the analysis of mesostructures, paleostress fields with the predominant horizontal northwest compression were determined. The data on earthquakes that occurred in September 2018 near the town of Katav-Ivanovsk are analyzed. Contradictions in determination of the epicentral coordinates and focal mechanisms of these earthquakes calculated by different geological services are revealed. It is shown that the setting of right-lateral transpression, under which the structure of the northwestern part of the Bashkir megaanticlinorium formed, is still maintained at present.
