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 …

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 …

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 draw connections between seismic tomography, adjoint methods popular in climate and
ocean dynamics, time-reversal imaging and finite-frequency 'banana-doughnut'kernels. We …

The conserved histone variant H2AZ has an important role in the regulation of gene
expression and the establishment of a buffer to the spread of silent heterochromatin. How …

We present tomographic evidence for the existence of deep-mantle thermal convection
plumes. P-wave velocity images show at least six well-resolved plumes that extend into the …

We use body wave ray theory in conjunction with the Born approximation tocompute 3-D
Fréchet kernels for finite-frequency seismic traveltimes, measured by cross-correlation of a …

In global-scale seismic tomography, teleseismic P and PP waves mainly constrain structures
in the upper two thirds of the mantle, whereas core-diffracted waves (Pdiff) constrain the …

Lithospheric deformation throughout Anatolia, a part of the Alpine–Himalayan orogenic belt,
is controlled mainly by collision-related tectonic escape of the Anatolian Plate and …

We provide an introduction to the use of the spectral-element method (SEM) in seismology.
Following a brief review of the basic equations that govern seismic wave propagation, we …
