Based on the research results of the non-linear dynamic model which consists of a plane network system built by spring-slider-damper, cellular automata model is developed from 2D to 3D, with the evolution rule modified. The authors design 100×100×40 grids for 3D cellular automata model, and produce 13540 synthetic seismic events. The computation results show that the tempo-spatial distribution of 3D synthetic events is consistent with that of actual natural earthquakes, and frequency-magnitude of synthetic seismic events meets G-R relation. Moreover, the synthetic events by cellular automata have fractal distribution on tempo-spatial scale. Compared with 2-D model, 3D cellular automata is more reasonable.
