Simulation of Seismic Wave Propagation using Cellular Automata

Abstract

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