ANOMALIES OF CHANGES IN HYDROGEOCHEMICAL PARAMETERS (Cl⁻, CO₂, EH, T) OF THE CHIMYON NP-1 WELL UNDER THE INFLUENCE OF THE M=5.7 EARTHQUAKE
Hydrogeochemical changes associated with earthquakes are considered as a potential tool for detecting earthquake signals. The
article presents the results of scientific analysis of seismological monitoring data conducted by the Republican Center for
Seismological Monitoring of the Ministry of Emergency Situations of the Republic of Uzbekistan at the Institute of Seismology,
which analyzed the changes in the hydrogeoseismological parameters Cl⁻, CO₂, EH, PH, Tº in the “Chimyon NP1” well in the
Fergana geodynamic polygon during the preparatory phase of the earthquakes that occurred in 2025. As a result of the analysis,
graphs were drawn and anomalous periods of each parameter were determined. These results prove that hydrogeochemical
monitoring can be very effective for seismic monitoring.
