Junlun LI Department of Earth, Atmospheric and Planetary Sciences, MIT Introduction Finite difference scheme has been widely used to solve elastic wave propagation in heterogeneous and layered media. Traditionally, staggered grid scheme is used for differencing the equations of Newton’s Motions Law and Generalized Hook’s Law describing the elastic wave propagation. In the two dimensional case, the equations can be expressed as follow:
