For allocation irregular signals in changes of electrotelluric potentials differences in system of measuring lines which situated in Verchnya Paratunka station the estimation of parameters of singularity spectrum in moving time window and time series of generalized Hurst indexes have been made. For diagnostics of synchronization signals in changes of multivariate series of generalized Hurst indexes the analysis of evolution of component-wise canonical coherences product in time-and-frequency field in comparison with seasonal changes air temperature, power of average daily K-index geomagnetic activity variations and instantces of power earthquakes. Synchronization signals in changes of noise components of electrotelluric potentials difference by time may correspond to higher Earth geomagnetic field perturbation and spring-summer periods with positive air temperatures have been determined.
