Seismic wave propagation and scattering in the heterogeneous earth /

Seismic wave propagation and forward and inverse waveform modeling have been used extensively to investigate the structure of Earth. Recent seismological studies suggest that Earth is a random medium with a broad spectrum of spatial velocity fluctuations resulting in seismic wave scattering. Sato and Fehler present new developments on seismic wave propagation and scattering through the randomly heterogeneous structure of Earth's lithosphere and introduce different aspects and methods of scattering in acoustic and elastic materials and their applications in analyzing seismic data on various scales. Chapters include phenomenological modeling of coda-wave excitation, Born approximation for wave scattering in inhomogeneous media, attenuation of high-frequency seismic waves in the lithosphere, synthesis of three-component seismogram envelopes for earthquakes, envelope synthesis based on radiative transfer theory, and a review of parabolic approximation for scalar waves and its stochastic treatment. The last chapter summarizes the results of the studies on modeling high-frequency seismic wave propagation through the randomly inhomogeneous structure of the lithosphere and discusses possible future developments. A working knowledge in advanced calculus and physics is needed to take advantage of the mathematics of scattering theory and observations of various theoretical methods.
