"The phenomenon of earthquake clustering, i.e., the increase of occurrence probability for seismic events close in space and time\nto other previous earthquakes, has been modeled both by statistical and physical processes.\nFrom a statistical viewpoint the so-called epidemic model (ETAS) introduced by Ogata in 1988 and its variations have become\nfairly well known in the seismological community. Tests on real seismicity and comparison with a plain time-independent\nPoissonian model through likelihood-based methods have reliably proved their validity.\nOn the other hand, in the last decade many papers have been published on the so-called Coulomb stress change principle, based\non the theory of elasticity, showing qualitatively that an increase of the Coulomb stress in a given area is usually associated with an\nincrease of seismic activity. More specifically, the rate-and-state theory developed by Dieterich in the ′ 90s has been able to give a\nphysical justification to the phenomenon known as Omori law. According to this law, a mainshock is followed by a series of\naftershocks whose frequency decreases in time as an inverse power law.\nIn this study we give an outline of the above-mentioned stochastic and physical models, and build up an approach by which\nthese models can be merged in a single algorithm and statistically tested. The application to the seismicity of Japan from 1970 to\n2003 shows that the new model incorporating the physical concept of the rate-and-state theory performs not worse than the purely\nstochastic model with two free parameters only. The numerical results obtained in these applications are related to physical\ncharacters of the model as the stress change produced by an earthquake close to its edges and to the A and σ parameters of the rate-\nand-state constitutive law."^^ .
