Variations of Dissolved Helium and Radon Caused by Earthquakes in Groundwater of the Southern Cis-Baikal Region

Аннотация

This paper reports on variations in the concentrations of dissolved radon, registered in groundwaters of the Southern Cis-Baikal region run-up to earthquakes of different energy classes, located at different distances from the point of geochemical observations. Using the obtained data, an equation of regression was calculated for the relationship between the log(TR) function and the energy class of earthquakes. These data can be used as signs of short-term earthquake precursors.
