EXPLOITING SEISMIC WAVEFORMS: CORRELATION, HETEROGENEITY AND INVERSION

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.

Brian Kennett is Emeritus Professor of Seismology at the Australian National University. His research interests are directed towards understanding the structure of the Earth from seismological observations. He is the recipient of numerous awards and medals for his work and is a Fellow of the Australian Academy of Sciences and the Royal Society (London). He the author of more than 300 research papers and nine books.

Andreas Fichtner is Professor of Seismology and Wave Physics at ETH Zurich. His work is focused on the development of waveform tomography methods using high-performance computing, and their application in seismology and medical imaging. He is the recipient of several awards, including the 2011 Aki award of the American Geophysical Union, and is the editor or author of three other books.
