Seismological models of upper-mantle structure are providing new constraints on the
physical and chemical properties that differentiate the lithosphere from the asthenosphere. A …

The goal of this paper is to provide an overview of the current state of the art in seismic
tomography, and trace its origins from pioneering work in the early 1970s to its present …

Recent progress in numerical methods and computer science allows us today to simulate
the propagation of seismic waves through realistically heterogeneous Earth models with …

We propose a method to invert surface wave dispersion data directly for 3-D variations of
shear wave speed, that is, without the intermediate step of phase or group velocity maps …

Summary Empirical Green's functions (EGFs) between pairs of seismographs can be
estimated from the time derivative of the long-time cross-correlation of ambient seismic …

Observations of seismic anisotropy yield some of the most direct constraints available on
both past and present-day deformation in the Earth's mantle. Insight into the character of …

Understanding the geotectonic evolution of the southeastern Tibetan plateau requires
knowledge about the structure of the lithosphere. Using data from 77 broadband stations in …

We present a full seismic waveform tomography for upper-mantle structure in the
Australasian region. Our method is based on spectral-element simulations of seismic wave …

The lithosphere–asthenosphere boundary (LAB) is a first-order structural discontinuity that
accommodates differential motion between tectonic plates and the underlying mantle …

The shear modulus and attenuation of pure and therefore genuinely melt-free polycrystalline
aggregates of Fo90 olivine have recently been measured over a wide range of mean grain …
