Query: Non-Poisson distribution of the time distances between two consecutive
  clusters of earthquakes   With the help of the Diffusion Entropy technique we show the non-Poisson
statistics of the distances between consecutive Omori's swarms of earthquakes.
We give an analytical proof of the numerical results of an earlier paper
