Power-law time distribution of large earthquakes

Articolo
Data di Pubblicazione:
2003
Abstract:
We study the statistical properties of time distribution of seismicity in California by means of a new method of analysis, the diffusion entropy.We find that the distribution of time intervals between a large earthquake (the main shock of a given seismic sequence) and the next one does not obey Poisson statistics, as assumed by the current models.We prove that this distribution is an inverse power law with an exponent 2:06 0:01.We propose the long-range model, reproducing the main properties of the diffusion entropy and describing the seismic triggering mechanisms induced by large earthquakes.
