dc.description.abstract	This paper presents the results of a multivariate analysis of changes in groundwater table and chemistry observed in wells and springs at the Petropavlovsk Geodynamic Site during 1986-1992. The objective was to identify time intervals and frequency bands where the scalar time series of the observed parameters showed synchronous behavior. It is supposed that synchronous changes in some or other parameter at different sites or in physically different parameters at one site may be indicative of an imminent earthquake. It is shown that this method help to detect both postseismic synchronous signals and periods of the synchronous behavior of several precursors related to earthquake preparation.
