The problem of earthquake prediction and the methods of identification of geophysical precursory signals are discussed. To get information on the dynamics of earthquake preparation processes, fluctuations in geophysical time series are analyzed with the method of flicker-noise spectroscopy. Integral indices ? power spectra and various moments ("structural functions") ? are used as information relations. We demonstrate that the method allows us to reveal earthquake precursors.
