"The statistics of time delays between successive earthquakes has re-\ncently been claimed to be universal and to show the existence of clustering beyond\nthe duration of aftershock bursts. We demonstrate that these claims are unjustified.\nStochastic simulations with Poissonian background activity and triggered Omori-\ntype aftershock sequences are shown to reproduce the interevent-time distributions\nobserved on different spatial and magnitude scales in California. Thus the empirical\ndistribution can be explained without any additional long-term clustering. Further-\nmore, we find that the shape of the interevent-time distribution, which can be ap-\nproximated by the gamma distribution, is determined by the percentage of main-\nshocks in the catalog. This percentage can be calculated by the mean and variance\nof the interevent times and varies between 5% and 90% for different regions in\nCalifornia. Our investigation of stochastic simulations indicates that the interevent-\ntime distribution provides a nonparametric reconstruction of the mainshock\nmagnitude-frequency distribution that is superior to standard declustering algorithm."^^ .
