Exploiting Seismic Waveforms

Developments in seismology including correlation techniques, heterogeneity and waveform inversion, illustrated with observational examples.

An overview of recent developments in seismology including the application of correlation techniques, multi-scale heterogeneity and the extraction of structure and source information by seismic waveform inversion. Describing algorithms and examples of waveform inversion, it provides an excellent resource for students and researchers in seismology.Exploiting Seismic Waveforms introduces a range of recent developments in seismology including the application of correlation techniques, understanding of multi-scale heterogeneity and the extraction of structure and source information by seismic waveform inversion. It provides a full treatment of correlation methods for seismic noise and event signals, and develops inverse methods for both sources and structure. Higher frequency components of seismograms are frequently neglected, or removed by filtering, but they contain information about seismic structure on scales that cannot be revealed by seismic tomography. Sufficient computational resources are now available for waveform inversion for 3-D structure to be a practical procedure and this book describes suitable algorithms and examples reflecting current best practice. Intended for students and researchers in seismology, this book provides a physical understanding of seismic waveforms and the way that different aspects of the seismic wavefield are revealed by the way that seismic data are handled.
