Abstract

Time dynamics of self-potential, geochemical and meteorological parameters, simultaneously recorded in a CO₂ degassing area at Soos, NW-Bohemia (Czech Republic), have been investigated. The power spectra, behaving as power-law function of the frequency, show the presence of colored-noise-type dynamics. The Higuchi analysis reveals the observed geophysical signals to have the property of fractal curves, with the identification of different scaling regimes. The Detrended Fluctuation Analysis, removing trends and non-stationarities, has shown that the signals present clear fingerprints of long-range correlated fluctuations.
