Abstract. Monitoring series of the Na/Li thermophilic ratio in groundwater obtained at the station 27 of the Kultuk polygon in 2012–2022 is compared with those of the Si thermophilic element concentrations. Discrepancies in time variations of calculated temperatures are used to identify reservoir groundwater components that exhibit a hydrogeodynamic center subjected to coseismic generation of friction clay.
Keywords: groundwater, monitoring, Na/Li, Si, geothermometer, earthquakes, friction clay, Baikal.
