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 is a powerful tool for illuminating Earth structure across a range of
scales, but the usefulness of any image that is generated by this method is dependent on …

Reflection tomography is an inversion method that adjusts a velocity and retkctor depth
model to be consistent with the prestack time data. This tomography approach minimizes lhe …

Seismic data represent one of the most valuable resources for investigating the internal
structure and composition of the earth. One of the first people to deduce earth structure from …

Seismic inversion aims to reconstruct a quantitative model of the Earth subsurface, by
solving an inverse problem based on seismic measurements. There are at least three …

We introduce a new tomographic method for estimating velocity macro-models from seismic
reflection data. In addition to traveltimes picked on locally coherent reflected events, the …

Traditional grid-based eikonal schemes for computing traveltimes are usually confined to
obtaining first arrivals only. However, later arrivals can be numerous and of greater …

Kinematic information for constructing velocity models can be extracted in a robust way from
seismic prestack data with the common-reflection-surface (CRS) stack. This data-driven …

Publisher Summary This chapter describes a variety of schemes for tracking the kinematic
evolution of high frequency seismic waves in heterogeneous 2-D and 3-D structures. Where …

A number of techniques are employed to overcome nonuniqueness and instability inherent
in linear inverse problems. To test the factors that enter into the selection of an inversion …
