- Аннотация: Abstract. The informativity of the time variation of geophysical fields for earthquake prediction is discussed. A review of previous studies on spectral-time analysis of long-term realizations of various geophysical parameters observed at the Garm prognostic test range in Tadjikistan has shown substantial time variability for all geophysical fields. Similar periodic components, ranging from a few months to several years, were detected in time variations of these parameters. This may indicate common regional or global oscillational factors controlling the structure of these variations. There is virtually not significant correlation between variations of these parameters and the moments of strong earthquakes. Physical and mathematical questions posed by analysis of time series used in earthquake prediction are discussed in this context. In particular, the feasibility is considered of forming dynamic space-time structures in geophysical fields to be utilized for earthquake prediction.
