摘要: A statistical analysis of electric self-potential time series measured in an active seismic region the state Guerrero Mexico is presented. The fractal dimension D these calculated using Higuchi’s algorithm. Most have ≈ 2, corresponding to uncorrelated white noise. However, there exist intervals where remarkably less than two, correlated signals. There are no clear correlations between D-changes and impending earthquakes. Nevertheless, some weeks before earthquake M = 7.4 with epicenter 110 km from Acapulco, reached its lowest value almost four years. possibility that corresponds charge patterns arising self-organized critical phenomena discussed.
