Abstract:
We analyse a seismic catalogue of South California to investigate the possibility of earthquake prediction using the hypothesis that the seismic events are self-organized critical phenomena. The relation found previously is valid only in a mean field approximation, but cannot be used for earthquake prediction because the time clustering of seismic events makes the definition of a standard deviation of waiting times of earthquakes impossible.
