Zusammenfassung |
Recently, it has been proposed a new method to investigate the
linear/nonlinear properties of a time series by decomposing it into two
sub-series: magnitude and sign sub-series (Ashkenazy et al., 2003). The
long-range correlation properties of the magnitude and sign sub-series
relate to nonlinear and linear behavior of the original time series
respectively. We apply this method to the hourly time variability of
geoelectrical signals, measured from January 2001 to September 2002 by four
stations installed in Basilicata region (southern Italy). Three stations
(Giuliano, Marsico and Tito) are located in a seismic area, and one
(Laterza) in a low-seismicity area. A site-dependence of the
linear/nonlinear properties has been shown, revealing that different
dynamics govern signals measured in seismic and low-seismicity areas. |
