Abstract: A new lattice Boltzmann model was proposed for simulating the seismic pressure wave. Using ChapmanEnskog expansion and multi scale technique to the pressure distribution function, we obtained the moments of the seismic pressure wave equations and the distribution function. Using this model, we simulated the multiseismic pressure waves motion. These numerical results can be compared with the results simulated by the finite differential method.

Key words: lattice Boltzmann model, seismic pressure wave, multi seismic resources
