This book focuses on recent developments in the area of seismic wave propagation and scattering through the randomly heterogeneous structure of the Earth, with emphasis on the lithosphere. The presentation combines information from many sources to present a coherent introduction to the threory of scattering in acoustic and elastic materials and includesanalyses of observations using the theoretical methods developed.

Seismic waves, both natural and man-made, reveal much information about the Earths interior, and recent advances expose the limitations of classical theory and analysis. It reflects the growing realization that the Earths crust contains many irregular components that transmit seismic waves in diverse ways, yet that these irregularities can be detected using advanced analytical methods. Comprehensive survey of the latest developments in seismic wave propagation and analysis and the first coherent introduction to the theory of scattering. Focuses on recent developments in the area of seismic wave propagation and scattering through the randomly heterogeneous structure of the Earth, with emphasis on the lithosphere. Includes discussions and analyses of observations using the latest theoretical methods, assisting the reader to see the practical use of the methods for characterizing the Earth. Successfully integrates information from different sources to provide a thorough discussion.
