Seismic wave propagation and scattering in the heterogenous earth

Seismic waves – generated both by natural earthquakes and by man-made sources– have produced an enormous amount of information about the Earth's interior.In classical seismology, the Earth is modeled as a sequence of uniform horizontal layers (or sperical shells) having different elastic properties and one determines these properties from travel times and dispersion of seismic waves. The Earth, however, is not made of horizontally uniform layers, and classic seismic methods can take large-scale inhomogeneities into account. Smaller-scaleirregularities, on the other hand, require other methods. Observations of continuous wave trains that follow classic direct S waves, known as coda waves, have shown that there are heterogeneities of random size scattered randomly throughout the layers of the classic seismic model. This book focuses on recent developments in the area of seismic wave propagation and scattering through therandomly heterogeneous structure of the Earth, with emphasis on the lithosphere. 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 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 INDICE: Introduction.- Heterogeneity in the Lithosphere.- PhenomenologicalModeling of Coda Wave.- Excitation Born Approximation for Wave.- Scattering in Inhomogeneous Media.- Attenuation of High-frequency Seismic Waves Synthesis of the Three-component Seismogram Envelopes.- Envelope Synthesis Based on Radiative Transfer.- Theory Broadening of Seismogram Envelopes.- Summary and Epilog.
