Приведен пример обработки временных рядов GPS-наблюдений для оперативного исследования горизонтальных косейсмических смещений при Хубсугульском землетрясении в Монголии 11 января 2021 г. (М=6.7). Разработан методический подход для изучения косейсмических смещений в момент землетрясения. В работе представлены результаты определения значений горизонтальных косейсмических смещений, которые в зоне сочленения Хубсугульской и Тункинской впадин составляют 0.6 мм, а для районов Сибирского блока и Забайкалья – сотые доли миллиметра. Для станций, расположенных на южной окраине Сибирского блока, и станций Забайкалья, косейсмические смещения направлены на запад. Рассчитанные векторы смещений близлежащих к эпицентру станций (MNDY и BADG) направлены на юго-восток. 

The research provides an example of the GPS time series processing for monitoring of horizontal coseismic displacements during the 11 January 2021 M 6.7 Hovsgol earthquake, Mongolia. There has been developed a methodological approach to the study of coseismic displacements at the time of the earthquake. This paper presents the results of determining the values of horizontal coseismic displacements which are 0.6 mm in the junction zone between the Hovsgol and Tunka depressions and hundredths of a millimeter for the Siberian block and Transbaikalia areas. For stations located on the southern margin of the Siberian block and stations in Transbaikalia, the vectors of coseismic displacements are directed to the west. The calculated displacement vectors of the stations near the epicenter (MNDY and BADG) are directed to the southeast.
