Abstract
In tins study, a simulation method of seismic wave propagation was constructed using the Cellular Automaton method Aground, which is an analytical domain, was divided into cells and the local rules to update state parameters between cells were constructed as well as the local rules about the reflection and transmission between grounds. The intermittent update method was also proposed to adjust the difference of propagation speed of wave. The validity of the method was checked by the comparison of the simulation result with the theoretical one and the measured one and the results agreed well. It was considered that the method constracted in this study was efficient for actual applications.
