Abstract

Multifractal analysis was performed to characterize the fluctuations in dynamics of the hourly time variability
of self-potential signals measured from January 2001 to September 2002 by three stations installed in the Basilicata
region (Southern Italy). Two stations (Giuliano and Tito) are located in a seismic area, and one (Laterza)
in an aseismic area. Multifractal formalism leads to the identification of a set of parameters derived from the shape of the multifractal spectrum (the maximum a0, the asymmetry B and the width W) and measuring the «complexity» of the signals. Furthermore, the multifractal parameters seem to discriminate self-potential signals
measured in seismic areas from those recorded in aseismic areas.
