Abstract

This chapter reviews numerical methods used to simulate global seismic wave propagation. Following a brief discussion of the challenges associated with generating synthetic seismograms on a global scale, we distinguish 'strong' and 'weak' implementations of the governing equations. Differential or strong methods discussed in this chapter include finite difference and pseudospectral techniques, and integral or weak methods discussed in this chapter include coupled mode, direct solution, finite element, and spectral element techniques. We conclude by discussing the potential for using 3D simulations to address the inverse problem in global seismology.
