Elastic wavefield modelling in 3D by fourth-order staggered- grid finite difference technique

Zhengsheng Yao and Gary F. Margrave

ABSTRACT

The velocity-stress finite-difference formulation for wave propagation through 3D elastic media is presented. The wave equations are solved by a finite-difference scheme using fourth-order spatial operators and a second order temporal operator on a staggered grid. The condition for the stability and dispersions are discussed.
