Journal ArticleDOI
Full seismic waveform tomography for upper-mantle structure in the Australasian region using adjoint methods
TL;DR: In this paper, the authors present a full seismic waveform tomography for upper-mantle structure in the Australasian region, based on spectral-element simulations of seismic wave propagation in 3-D heterogeneous earth models.
Journal ArticleDOI
The adjoint method in seismology: I. Theory
TL;DR: In this article, Tarantola et al. presented a mathematical formalism that generalises the derivation of the adjoint problem for the scalar wave equation in two dimensions, where the objective function is chosen as the L 2 distance between the modelled wave field and real data.
Journal ArticleDOI
Anisotropic wave propagation through finite‐difference grids
TL;DR: In this article, the authors proposed an algorithm to solve the elastic-wave equation by replacing the partial differentials with finite differences, which enables wave propagation to be simulated in three dimensions through generally anisotropic and heterogeneous models.
Journal ArticleDOI
Theoretical background for continental‐ and global‐scale full‐waveform inversion in the time–frequency domain
TL;DR: In this article, a new approach to full seismic waveform inversion on continental and global scales is proposed, based on the time-frequency transform of both data and synthetic seismograms with the use of time and frequency-dependent phase and envelope misfits.
Journal ArticleDOI
An arbitrary high-order Discontinuous Galerkin method for elastic waves on unstructured meshes — III. Viscoelastic attenuation
TL;DR: The development of the highly accurate ADER–DG approach for tetrahedral meshes including viscoelastic material provides a novel, flexible and efficient numerical technique to approach 3-D wave propagation problems including realistic attenuation and complex geometry.
