Description/Abstract During buildup of earthquakes many investigators have observed an increase of the content of certain chemical, gaseous, and isotope components of groundwaters, and after the main shock comparatively rapid restoration was noted.^The changes in composition are selective with respect to components, depend on the particular geological, hydrogeological-hydrochemical, and seismic conditions, and were detected at considerable distances from the earthquake focal zone at depths accessible to hydrogeological wells and in surface outflows.^Radon is a short-lived isotope, and therefore no model of its transport from the focal zone is suitable for explaining the observed changes in its content in groundwaters far from the focus.^It is necessary to assume that it is released whenever increased stress is created in rock mass.^The possibility of explaining variations of radon content in waters of seismically active regions is examined.^An essential and in certain cases a decisive role in the formation and decrease of the hydrochemical signal is played by the residence time of the water in the system.^The property of systems which substantially affects the very manifestation and contrast of hydrogeochemical signals is the average residence time of the water in the system and of the given component in the solution.^12 references, 2 figures.
