We propose a new approach to investigate the possible correlation between electrical signals and earthquakes. Good correlation has been found between the spectral power-law exponent of geoelectrical signals and the Hurst exponent of the seismicity of the area investigated. A tendency of both parameters to converge toward unity, typical of self-organized critical dynamics, is evident before the occurrence of the major event recorded in the area during the observation period.

Abstract
We propose a new approach to investigate the possible correlation between electrical signals and earthquakes. Good correlation has been found between the spectral power-law exponent of geoelectrical signals and the Hurst exponent of the seismicity of the area investigated. A tendency of both parameters to converge toward unity, typical of self-organized critical dynamics, is evident before the occurrence of the major event recorded in the area during the observation period.File in questo prodotto:
