Spectral-Element and Adjoint Methods in Seismology (2008, unknown): “Initially the method was applied to 2D seismic wave propagation problems [15, 50], but currently the SEM is widely used for 3D regional [21, 28, 29, 33, 37, 55] and global [10–12,30,31,35,36] seismic wave propagation.”
Forward and adjoint simulations of seismic wave propagation on fully unstructured hexahedral meshes (2011, methodology): “This issue becomes important when high-order time marching is required to reduce numerical dispersion in difficult case studies that involve complex media with poroelastic or viscoelastic rheologies (Martin et al. 2008b, 2010) or Newtonian compressible fluids (Martin & Couder-Castaneda 2010).”
A Newton-CG method for large-scale three-dimensional elastic full-waveform seismic inversion (2008, background): “The advent of highly parallel supercomputers over the past decade has opened the door to quantitative seismic hazard analysis based on large-scale high-resolution simulation of 3D seismic wave propagation in heterogeneous elastic regions [3, 12, 23, 28, 33].”

Strain Green's Tensors, Reciprocity, and Their Applications to Seismic Source and Structure Studies (2006, background): “Recent developments in both waveform modeling techniques and high-performance computational facilities have also helped seismologists to pursue the waveform approach at relatively short periods in ever more complex structural environments (e.g., Olsen, 1994; Graves, 1996; Komatitsch et al., 2004).”
