Operational Analysis of Weekly Quasi-Periodical Variations in Groundwater Redox Potential and Earthquakes of the Baikal Rift System in mid-2025

In mid-2025, a state of the BRS earth's crust, characterized by a weekly quasi-periodicity of mutually coordinated hydrogeochemical and seismic processes, is determined. Variations in oxidation-reduction potential of groundwater are associated with displaying impulses of extension and compression of the earth's crust. It is suggested that the observed weekly quasi-periodic processes are indicative of the earth's crust entry into a state of resonance on a scale of the entire BRS that may entail the realization of a new strong earthquake. Taking into account the established dependence of the earthquake energy class (K) on the time interval between earthquakes in the east of the BRS, it is proposed that a new seismic event with K > 13 will occur, when the time interval between earthquakes goes beyond the upper limit of the weekly resonant values in impulses of extension and compression of the earth's crust.
