  • Abstract
    A third-order spectral analysis for the detection of nonlinearities in geoelectric signals is presented in this work. Specifically, the bispectrum and bicoherence function are employed for the case of the geoelectrical signal acquired over the period of 1993-2002 in the area of Patras, Greece. This is an area of intense seismic activity and the possible relation between this activity and the non-linear mechanism of the geoelectrical signal is explored
