Seismic anisotropy has been found in many regions of the Earth's interior. Its presence in the
Earth's crust has been known since the 19th century, and is due in part to the alignment of …

Building on global adjoint tomography model GLAD-M15, we present transversely isotropic
global model GLAD-M25, which is the result of 10 quasi-Newton tomographic iterations with …

We present the first-generation global tomographic model constructed based on adjoint
tomography, an iterative full-waveform inversion technique. Synthetic seismograms were …

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 …

Structural geologists are well aware of the fact that isotropic rocks are quite exceptional in
nature. Whicheverorigin, sedimentary, metamorphicormagmatic, rocks are shaped with a …

We combine a new, large data set of surface wave phase anomalies, long‐period
waveforms, and body wave travel times to construct a three‐dimensional model of the …

How cratons—extremely stable continental areas of the Earth's crust—formed and remained
largely unchanged for more than 2,500 million years is much debated. Recent studies of …

Since the 1960s seismologists have mapped anisotropy in the uppermost mantle, the mantle
transition zone, and the D ″region. When combined with constraints from mineral physics …

We present a 3-D radially anisotropic S velocity model of the whole mantle (SAW642AN),
obtained using a large three component surface and body waveform data set and an …

We present a tomographic model of radially anisotropic shear velocity variations in the
Earth's mantle based on a new compilation of previously published data sets and a variable …
