Resumen:

In this work we studied the multifractal spectrum behavior calculated during the presence of a possible seismic electric signal (SES). This signal was detected in geolectrical time series registered prior a seism of M6.7 occurred on October 24, 1993 in México. We calculated the multifractal spectrum by using no overlapping windows of segments of 1 hour. Our results display the singularities spectrum calculated before, during and after possible SES, showing important differences in some parameters like the width and maxima values, among others, in the spectra. Those observations suggest that the physical system has different dynamical features along these processes and possibly as a precursor sign. © 2015 IEEE.
