Opis

In recent years, the increased availability and fidelity of broadband seismic instruments have effectively narrowed the gap between exploration and global seismic applications. Global seismologists are now able to take advantage of high-resolution, often exploration-based, tools to examine rock properties tens to hundreds of kilometers below surface. This book reviews the key assumptions, algorithms and prospects of several important array-based methods in today's global and regional seismic surveys. A short list of topics includes data migration, PP and SS precursors, Radon transform, mantle triplication, P-to-S and S-to-P converted waves, shear-wave splitting, high-resolution seismic tomography, and ambient-noise interferometry. Each approach is presented in a 'cookbook' fashion for easy comparison, implementation and critique by the general readership.

Recenzje

From the reviews:

"Arrays - not individual stations - are now seismology's standard observational tool. Here is a book that cogently presents the methods that can turn the resulting explosion of data into creative insights about the earth."
William Menke, Professor of Earth and Environmental Sciences, Columbia University

"Dr. Gu has put together both a broad and in-depth source of information on modern array seismology. It is the first source I would recommend for new researchers planning to use that tool."
Brian Mitchell, Emeritus Reinert Professor of Earth Science Saint Louis University

"This special issue brings together a number of recent studies that use data from seismic arrays and the global seismic networks to resolve various aspects of mantle structure. It will be useful to a variety of researchers interested in new seismic processing methods and what they say about Earth structure."
Peter Shearer, Professor of Geophysics, Scripps Institution of Oceanography, University of California, San Diego

"This review is presented as a series of manuscripts from experts in specific fields. ... an excellent resource for anyone interested in array analysis. Many of the manuscripts are written in a practical way such that the reader can immediately use the techniques in their own research. ... Given the increase in the number of dense arrays that have been deployed in recent years, this book is a timely resource for the growing number of researchers who wish to utilize this data." (Eric Kiser, Pure and Applied Geophysics, Vol. 168, 2011)
