ABSTRACT

In this paper a potential - based model for earthquake simulation that is a two-dimensional cellular automaton dynamic system constituted of cells-charges, is presented. The proposed model is constructed in order to simulate earthquake activity in correspondence to the quasi-static two-dimensional version of the Burridge-Knopoff spring-block model of earthquakes, as well as, to the Olami-Feder-Christensen (OFC) earthquake model. The simulation results are found in good quantitative and qualitative agreement with the Gutenberg–Richter (GR) scaling relation predictions. Numerical results for various cascade (earthquake) sizes and different critical states are presented. Furthermore, the parameter of different neighbourhood in the proposed model is also explored.
