Analysis of earthquakes based on a dissipative cellular-automata model

Earthquakes are complex, destructive phenomena and to model them is extremely difficult. Many mathematical models have been reported that take into account empirical rules known in connection with the frequency statistics of recent earthquakes. The cellular automaton is a model for critical phenomena that provide particles to a cell and it can be applied to the earthquake process. However, the cell configuration of the previously proposed model is extremely simple. In this paper, we propose a model in which the cells are arranged with the simulated fault diagram randomly distributed. Considering the dissipation of the strain energy of earthquake waves, the distributions of the particles in analogy to the earthquake are partially reduced. The results of applying this model to actual fault diagrams are reported. (C) 1998 Scripta Technica.
