Seismic imaging: From classical to adjoint tomography (2012, methodology): “…finite-element method, spectral-element method (SEM), was introduced to seismology from computational fluid dynamics (Patera, 1984) for both global (Capdeville et al., 2003; Chaljub and Valette, 2004; Fichtner et al., 2009a; Komatitsch and Tromp, 2002a,2002b) and regional (Komatitsch et al., 2004;…”
Spectral-element simulations of global seismic wave propagation: II. Three-dimensional models, oceans, rotation and self-gravitation (2002, methodology): “The idea was introduced for global wave propagation by Taylor et al. (1997) and Chaljub (2000), and later used by Capdeville et al. (2002).”
Global upper-mantle tomography with the automated multimode inversion of surface and S-wave forms (2006, methodology): “Here we perform a resolution test of a new kind: we invert synthetic data computed by Qin et al. (2006) using the spectral-element method (Komatitsch et al. 2002; Capdeville et al. 2003) and a laterally heterogeneous mantle model.”
Inferring upper-mantle structure by full waveform tomography with the spectral element method (2011, methodology): “As we will see below, the group velocity data set is introduced in the inversion only after several iterations.”
Global adjoint tomography: first-generation model (2016, background): “D spectral-element simulations of wave propagation in the mantle coupled with a normal-mode solution in a spherically symmetric core (Capdeville et al. 2003; Lekić & Romanowicz 2011; French et al. 2013; French & Romanowicz 2014).”

Simulations of Ground Motion in the Los Angeles Basin Based upon the Spectral-Element Method (2004, background): “It was more recently introduced for global wave propagation by Chaljub (2000) and extended for large-scale global wave propagation (Komatitsch and Tromp, 2002a,b; Capdeville et al., 2003; Chaljub et al., 2003).”
Time‐reversal imaging of seismic sources and application to the great Sumatra earthquake (2006, methodology): “In this paper, we used 2 different numerical methods, the normal mode summation technique [Gilbert and Dziewonski, 1975] and the method coupling the spectral element method and the modal solution [Capdeville et al., 2003].”
Whole-mantle radially anisotropic shear velocity structure from spectral-element waveform tomography (2014, methodology): “This approach enables us to relax constraints on SEM time stability due to the crustal model (namely, in conjunction with the coupled SEM; Capdeville et al. 2003), allowing larger and fewer time-integration steps.”
