Spectral-infinite-element simulations of seismic wave propagation in self-gravitating, rotating 3-D Earth models

HN Gharti, W Eaton, J Tromp - Geophysical Journal International, 2023 - academic.oup.com
Although observation of gravity perturbations induced by earthquakes is possible, simulation
of seismic wave propagation in a self-gravitating, rotating Earth model with 3-D …

Adjoint sensitivity kernels for free oscillation spectra

S Adourian, MS Dursun, HCP Lau… - Geophysical Journal …, 2024 - academic.oup.com
We apply the adjoint method to efficiently calculate sensitivity kernels for long-period seismic
spectra with respect to structural and source parameters. Our approach is built around the …

On the modelling of self-gravitation for full 3-D global seismic wave propagation

M van Driel, J Kemper, C Boehm - Geophysical Journal …, 2021 - academic.oup.com
We present a new approach to the solution of the Poisson equation present in the coupled
gravito-elastic equations of motion for global seismic wave propagation in time domain …

On the elastodynamics of rotating planets

M Maitra, D Al-Attar - Geophysical Journal International, 2024 - academic.oup.com
Equations of motion are derived for (visco) elastic, self-gravitating and variably rotating
planets. The equations are written using a decomposition of the elastic motion that …

Some more problems of geodynamics
