Dependence of the manifestation’s time of a hydrochemical earthquake forecast in the southern part of the Lake Baikal from their energy classes and epicentral distances

Abstract

Have been studied the concentrations of dissolved helium in the water of a artesian well in the Southern Cis-Baikal region. It is established that on the eve of earthquakes they experience certain variations. Based on the obtained data, the correlation function lgτR (the logarithm of the time product of the harbinger of the seismic event at its epicentral distance) is calculated from the energy class of the earthquake. It is proposed to consider variations in the concentration of helium as a short-term precursor of earthquakes.
