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.
