This article examines the role of hydrogeoseismological precursors in earthquake prediction. Anomalous changes in gas-
geochemical, isotopic, and geophysical parameters of groundwater are analyzed as important indicators of the preparation
process of strong earthquakes. Based on long-term observations conducted in Uzbekistan after the 1966 Tashkent earthquake, a
hydrogeochemical database has been developed. Statistical analysis was carried out using CO₂ parameter data, and the
effectiveness of this method for medium- and short-term earthquake forecasting was assessed. The results demonstrate that the
hydrogeoseismological method is one of the reliable approaches for earthquake prediction.
