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 …

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 …

We document our tomographic method and present a new global model of three‐
dimensional (3‐D) variations in mantle P wave velocity. The model is parameterized by …

Measurements of the splitting or birefringence of seismic shear waves that have passed
through the Earth's mantle yield constraints on the strength and geometry of elastic …

This book describes the theory and practice of inverting seismic data for the subsurface rock
properties of the earth. The primary application is for inverting reflection and/or transmission …

Wave-equation traveltime tomography tries to obtain a subsurface velocity model from
seismic data, either passive or active, that explains their traveltimes. A key step is the …

Many previously published wave-equation-based methods, which attempt to automatically
invert traveltime or kinematic information in seismic data or migrated gathers for smooth …

In this work, an ultrasound computed tomography (USCT) system was employed to
investigate the fast-kinetic reactive crystallization process of calcium carbonate. USCT …

We propose the use of ℓ1 regularization in a wavelet basis for the solution of linearized
seismic tomography problems A m= d, allowing for the possibility of sharp discontinuities …
