Gidrogeoseismological studies of underground mineral waters by activation analysis

Neutron activation analysis (NAA) and charged particle activation analysis (ChPAA) for the determination of more 20 chemical elements contents in the samples of drying up remainder of the thermal-mineral water was elaborated which are used in the hydro-geo-seismology for the study of the nature of element concentration change connected with the process, coming and following of powerful earthquake. The continuous observation of chemical elements in the composition of mineral water showed that Cl, Br, J, Hg, Sb, 40K are changed strongly before the powerful earthquake and possess most strong property of the earthquake's harbinger. It is shown that the power of the earthquake are correlated with a average contents of Hg, 40K. The considerable change of the Sb, Cr, Sc contents also are shown
