Hydro geochemical precursors of strong earthquakes on the results of observations in the well 'Kajaran' and their relationship to the process of earthquake preparation

The analysis of a precursor 'geochemical quiescence' in connection with dynamics of process of preparation of strong earthquake is given. The character of preparation of strong seismic events in region is determined qualitatively. The theoretical model of preparation of seismic event, based on periodicity of activation of geodynamic processes in region and on duration of occurrence of a geochemical quiescence is given. Dynamics of preparation of seismic process is determined as periodic process with exponential increase of amplitude and increase of frequency toward the time of strong seismic event. By monitoring over dynamics of variation of chemical components in water the connection between different strong seismic events in the area has been established
