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 fundamental issues to be solved simultaneously: non-linearity, non-uniqueness, and instability. This book covers the basic theory and techniques used in seismic inversion, corresponding to Author: Yanghua Wang. The book is therefore tutorial in the sense that a student could learn about seismic ray theory by reading it, but it is also something of a technical manual for the seismologist to consult to find the best way to do this or that and the algorithms to do the : J Hudson.

The book has a tutorial. Building on the basic theory of linear inverse problems, the methodologies of seismic inversion are explained in detail, including ray-impedance inversion and waveform tomography etc.

The application methodologies are categorised into convolutional and wave-equation based groups. Following the brief introductory chapter, the book is organized into five topics, with a single chapter devoted to each topic.

These topics are 1) the equations of elastodynamics, 2) seismic rays and traveltimes, 3) dynamic ray tracing and paraxial ray methods, 4) ray amplitudes, and 5) ray-based synthetic by: Seismic ray theory This chapter provides a background on seismic ray theory.

The emphasis is placed on explanation and interpretation of the basic ingredients, rather than on the derivation of equations, which are well covered in existing literature. The most complete account of seismic ray theory available is the monograph by Cerveny´ˇ ().

Ray theory Introduction However, if the scale length of variations in λ and µ are large compared to the seismic wavelength, then P and S can be treated separately and the elastic wave equation is simpliﬁed.

Even so, solving the elastic wave equation requires exhaustive computational effort. Ray theory is an alternative approach in which a File Size: KB.

The simplest, yet very powerful, example of these HF methods is the seismic ray method (Babich, ; Karal and Keller, ). The great significance of the seismic ray method is its universality, effectiveness, conceptual clarity, and its ability to investigate various seismic body waves independently of other waves.We define tomography as an imaging technique which generates a cross-sectional picture (a tomogram) of an object by utilizing the object's response to the nondestructive, probing energy of an external source.

Seismic tomography makes use of sources that generate seismic waves which probe a geological target of interest. Figure 1(a) is an example configuration for. Summary. Seismic ray theory is developed ab initio (apart from one or two standard elementary results) with special emphasis on the variables ζ and a, where ζ = d log υ/d log r and α = 2/(1 — ζ).

Travel-time-distance relations are examined for a variety of types of velocity distribution, including the case α constant and cases where α and υ change Cited by:
