Abstract. On January 12, 2021, a strong earthquake occurred, the epicenter of which was located in the water area of Lake Khubsugul (Mongolian People's Republic). A feature of the Khubsugul earthquake was the prolonged aftershock activity. The period of seismic reactivation in the Khubsugul area coincided with detailed measurements of electrochemical parameters of groundwaters at the southwestern coast of Lake Baikal. Statistical analysis of seismic activity and changes in the measured groundwater parameters revealed connection between these processes.
Keywords: earthquake, Lake Khubsugul, Lake Baikal, electrochemical monitoring, statistical analysis.
