レイリー非線形振動子を用いた地震活動シミュレーター : 運用上の改良と検証 A Seismicity Simulator Consisting of Rayleigh's Nonlinear Oscillators : Evaluation by Real Seismicities
Maeda and Yokomori (1999) constructed a deterministic model consisting of coupled nonlinear oscillators laid on belt conveyors, where Rayleigh's friction is to be created between the oscillators and the conveyors. The model reproduces typical statistical properties of earthquakes; their magnitude follow the G-R law, and their occurrence sequences constitute Poisson processes. We show that the model has an approximate recurrence property. Introducing a new index, we investigate systematically relationship between simulated time intervals and quality of recurrence achieved. With model parameters suitably chosen, the model generates sequences matching to observed seismicity of Tohoku and Hokkaido regions in Japan.
