Получены значения очаговых параметров землетрясения – сейсмический момент землетрясения (M0=3.02·1017 Н·м), моментная магнитуда (Mw=5.6), размеры очага (2.43 км), величина сброшенного напряжения (1.26 МПа).</p><p>Проведенный с помощью приемников GPS/ГЛОНАСС анализ поведения ионосферы не выявил возмущений, вызванных Кударинским землетрясением, что, вероятнее всего, обусловлено относительно малой магнитудой этого землетрясения. Анализ рядов наблюдений в отношении Кударинского землетрясения показал эффективность использования оборудования центров коллективного пользования и пунктов комплексного мониторинга для исследования сейсмичности, которая является наиболее опасным природным процессом для Байкальского региона.</p></abstract><trans-abstract xml:lang="en"><p>According to the data obtained on the equipment of the IEC SB RAS complex monitoring base for hazardous geological processes "Buguldeika" (Shared Research Facilities "Geodynamics and Geochronology" of IEC SB RAS) and Shared Research Facilities "Angara" of ISTP SB RAS an analysis of the characteristics of the Kudarinsky earthquake (09.12.2020) and the behaviour of the ionosphere during this event was carried out. The source parameters of the earthquake were obtained – the seismic moment of the earthquake (M0=3.02·1017 N·m), the moment magnitude (Mw=5.6), the source radius (2.43 km), and the stress drop (1.26 MPa).</p><p>The analysis of the ionosphere behaviour carried out using GPS/GLONASS receivers did not reveal disturbances caused by the Kudarinsky earthquake, which is most likely due to the relatively small magnitude of this earthquake. An analysis of the observation series related to the Kudarinsky earthquake showed the efficiency of using the Core Facilities Centre equipment and complex monitoring bases for studying seismicity, which is the most dangerous natural process for the Baikal region.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Кударинское землетрясение</kwd><kwd>Байкальский рифт</kwd><kwd>сейсмичность</kwd><kwd>спутниковая геодезия</kwd><kwd>ионосферные возмущения</kwd><kwd>GPS</kwd><kwd>ГЛОНАСС</kwd><kwd>полное электронное содержание</kwd><kwd>ROTI</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Kudarinsky earthquake</kwd><kwd>Baikal rift</kwd><kwd>seismicity</kwd><kwd>satellite geodesy</kwd><kwd>ionospheric disturbances</kwd><kwd>GPS</kwd><kwd>GLONASS</kwd><kwd>total electron content</kwd><kwd>ROTI</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работы проводились в рамках проекта Минобрнауки РФ № 075-15-2020-787 «Фундаментальные основы, методы и технологии цифрового мониторинга и прогнозирования экологической обстановки Байкальской природной территории».
