    "abstract": "Mega et al.(cond-mat/0212529) proposed to use the ``diffusion entropy\u0027\u0027 (DE)\nmethod to demonstrate that the distribution of time intervals between a large\nearthquake (the mainshock of a given seismic sequence) and the next one does\nnot obey Poisson statistics. We have performed synthetic tests which show that\nthe DE is unable to detect correlations between clusters, thus negating the\nclaimed possibility of detecting an intercluster correlation. We also show that\nthe LR model, proposed by Mega et al. to reproduce inter-cluster correlation,\nis insufficient to account for the correlation observed in the data.",
