- Аннотация: Repeated manifestations of hydrogeochemical anomalies in groundwater ion contentvariations before local strong earthquakes were recorded in three flowing wells of the Petropavlovsk-Kamchatsky test site. A model of changes in chemical composition of groundwater is consideredusing observational data and modeling of two waters mixing with contrasting composition in azone of increased permeability in aquifer. Hydrodynamic parameters of the model—relaxation timeof water pressure impulses and the time of mixed water movement in aquifer and wellbore—canvary from days to hundreds of days in individual wells. These parameters determine the durationand morphological features of anomaly in mixed water from a well. Using observational data fromself-flowing well M-1, an assessment was made of chemical composition and mineralization oftwo mixing waters and their ratio in mixed water under background conditions and during thepreparation of earthquake on 2 March 1992, Mw = 6.9.
