Abstract: The time fluctuations of self-potential data, recorded at the monitoring station Acapulco (Mexico) during 1994–1996 in the seismic area of Guerrero–Oaxaca, are analyzed by means of the Fisher Information Measure (FIM), a nonlinear powerful method to investigate complex dynamics in time series. The time evolution of the FIM shows a clear correlation with the largest earthquakes that occurred in the monitored area during the observation period. Seismic precursory patterns in the FIM evolution are also revealed.
