Forward and adjoint simulations of seismic wave propagation on fully unstructured hexahedral meshes
TLDR
We present forward and adjoint spectral-element simulations of coupled acoustic and (an)elastic seismic wave propagation on fully unstructured hexahedral meshes. Expand

Unified Structural Representation of the southern California crust and upper mantle
We present a new, 3D description of crust and upper mantle velocity structure in southern California implemented as a Unified Structural Representation (USR). The USR is comprised of detailed basinExpand

A 14.6 billion degrees of freedom, 5 teraflops, 2.5 terabyte earthquake simulation on the Earth Simulator
TLDR
We use a very large mesh with 5.5 billion grid points (14.6 billion degrees of freedom) to model seismic wave propagation resulting from large earthquakes. Expand

Mantle‐driven uplift of Hangai Dome: New seismic constraints from adjoint tomography
The origin of Hangai Dome, an unusual large-scale, high-elevation low-relief landform in central Mongolia, remains enigmatic partly due to lack of constraints on its underlying seismic structure.Expand

Three-dimensional structure of the African superplume from waveform modelling
SUMMARY Previous 2-D modelling of seismic waveforms and traveltimes has revealed a large-scale ridge-like velocity anomaly beneath Africa, which is usually referred to as the African superplume.Expand

Near real‐time simulations of global CMT earthquakes
SUMMARY We have developed a near real-time system for the simulation of global earthquakes. Prompted by a trigger from the Global Centroid Moment Tensor (CMT) Project, the system automaticallyExpand

Antipodal focusing of seismic waves due to large meteorite impacts on Earth
SUMMARY We examine focusing of seismic waves at the antipode of large terrestrial meteorite impacts, using the Chicxulub impact as our case study. Numerical simulations are based on aExpand

Application of an elastoplastic spectral‐element method to 3D slope stability analysis
SUMMARY We implement a spectral-element method for 3D time-independent elastoplastic problems in geomechanics. As a first application, we use the method for slope stability analyses ranging fromExpand

Multiparameter adjoint tomography of the crust and upper mantle beneath East Asia: 1. Model construction and comparisons
We present a 3-D radially anisotropic model of the crust and mantle beneath East Asia down to 900 km depth. Adjoint tomography based on a spectral element method is applied to a phenomenal data setExpand

A normal mode treatment of semi-diurnal body tides on an aspherical, rotating and anelastic Earth
SUMMARY Normal mode treatments of the Earth’s body tide response were developed in the 1980s to account for the effects of Earth rotation, ellipticity, anelasticity and resonant excitation within theExpand
