Summary The Kamchatka Peninsula lies over a vigorous subduction zone where Pacific and
North American plates converge at a rate of almost 80 mm yr− 1. Earthquakes associated …

The regional and continental scale dynamics of North America and vicinity are explored
using a high-resolution model of mantle flow. The model is constrained by simultaneously …

Grain size, one of the most important microstructural properties of materials, evolves during
creep deformation to minimize the free energy of polycrystalline aggregates. We apply a …

The physics of rock deformation in the lithosphere governs the formation of tectonic plates,
which are characterized by strong, broad plate interiors, separated by weak, localized plate …

Efforts to couple mantle flow models with rheological theories of mineral deformation
typically ignore the effect of texture development on flow evolution. The fact that there are …

The development of crystallographic textures in olivine-rich rocks leads to a marked
anisotropy in viscosity of the upper mantle, strongly influencing a variety of large-scale …

Amplitude measurements of the transverse component of SKS waves, the so-called splitting
intensity, can be used to formulate a non-linear inverse problem to image the 3-D variations …

We show that SKS splitting in the westernmost United States (polarization of the fastest
shear waves and splitting times, including their back-azimuthal dependence) can be …

In order to test the hypothesis that seismic anisotropy in the lowermost mantle is caused by
the development of a post‐perovskite lattice preferred orientation, and that anisotropy can …

Flow‐induced mineral alignment in the Earth's mantle affects the nature of seismic wave
propagation. Since measurements of seismic travel time and shear wave splitting are a key …
