Seismic wavefield imaging of Earth's interior across scales

J Tromp - Nature Reviews Earth & Environment, 2020 - nature.com
Seismic full-waveform inversion (FWI) for imaging Earth's interior was introduced in the late
1970s. Its ultimate goal is to use all of the information in a seismogram to understand the …

Seismic tomography and the assessment of uncertainty

N Rawlinson, A Fichtner, M Sambridge… - Advances in …, 2014 - Elsevier
Seismic tomography is a powerful tool for illuminating Earth structure across a range of
scales, but the usefulness of any image that is generated by this method is dependent on …

Seismic structure of the upper mantle beneath eastern Asia from full waveform seismic tomography

K Tao, SP Grand, F Niu - Geochemistry, Geophysics …, 2018 - Wiley Online Library
To better understand the subsurface behavior of subducting slabs and their relation to the
tectonic evolution of the overriding plate, we conduct a full waveform inversion on a large …

Whole-mantle radially anisotropic shear velocity structure from spectral-element waveform tomography

SW French, BA Romanowicz - Geophysical Journal International, 2014 - academic.oup.com
The radially anisotropic shear velocity structure of the Earth's mantle provides a critical
window on the interior dynamics of the planet, with isotropic variations that are interpreted in …

Lithospheric foundering and underthrusting imaged beneath Tibet

M Chen, F Niu, J Tromp, A Lenardic, CTA Lee… - Nature …, 2017 - nature.com
Long-standing debates exist over the timing and mechanism of uplift of the Tibetan Plateau
and, more specifically, over the connection between lithospheric evolution and surface …

Full waveform inversion and the truncated Newton method

L Métivier, R Brossier, J Virieux, S Operto - SIAM Journal on Scientific …, 2013 - SIAM
Full waveform inversion (FWI) is a powerful method for reconstructing subsurface
parameters from local measurements of the seismic wavefield. This method consists in …

Structure of the European upper mantle revealed by adjoint tomography

H Zhu, E Bozdağ, D Peter, J Tromp - Nature Geoscience, 2012 - nature.com
Images of the European crust and upper mantle, created using seismic tomography, identify
the Cenozoic Rift System and related volcanism in central and western Europe. They also …

Multiscale full waveform inversion

A Fichtner, J Trampert, P Cupillard… - Geophysical Journal …, 2013 - academic.oup.com
We develop and apply a full waveform inversion method that incorporates seismic data on a
wide range of spatio-temporal scales, thereby constraining the details of both crustal and …

Hamiltonian Monte Carlo solution of tomographic inverse problems

A Fichtner, A Zunino, L Gebraad - Geophysical Journal …, 2019 - academic.oup.com
We present the theory for and applications of Hamiltonian Monte Carlo (HMC) solutions of
linear and nonlinear tomographic problems. HMC rests on the construction of an artificial …

Resolution analysis in full waveform inversion

A Fichtner, J Trampert - Geophysical Journal International, 2011 - academic.oup.com
We propose a new method for the quantitative resolution analysis in full seismic waveform
inversion that overcomes the limitations of classical synthetic inversions while being …
