Phase transformations in mantle mineralogies probably cause the transition zone seismic
discontinuities, nominally at 410, 520, and 660 km depth. Thermodynamic principles govern …

Seismic tomography has been a vital tool in probing the Earth's internal structure and
enhancing our knowledge of dynamical processes in the Earth's crust and mantle. While …

We stack long‐period, transverse‐component seismograms recorded by the Global Digital
Seismograph Network (GDSN)(1976–1996), Incorporated Research Institutions for …

We use a coupled surface wave version of the Born approximation to compute the3-D
sensitivity kernel KT (r) of a seismic body wave traveltime T measured by cross-correlation of …

We develop methodologies to obtain accurate measurements of shear wave splitting and
apply these techniques to examine the pattern of oceanic upper mantle anisotropy. To …

D Born–Fréchet traveltime kernel theory is recast in the context of scalar-wave propagation
in a smooth acoustic medium, for simplicity. The predictions of the theory are in excellent …

▪ Abstract We review the present status of global mantle tomography and discuss two main
classes of models that have been developed in the past 10 years: P velocity models based …

SS and PP precursors are currently the only body wave data types that have significant
coverage in both oceanic and continental regions to study the existence and characteristics …

A global‐scale analysis of travel times of the mantle Pds phases (converted from P to S from
the discontinuity at a depth d beneath the receiver) is presented. Most of the data are related …

Seismic arrays, first introduced in the late 1950s to detect underground nuclear explosions,
have helped to improve our knowledge about the structure of the Earth for the last 40 years …
