Seismic anisotropy is ubiquitous at both the microscopic and macroscopic scales. The goal of this multidisciplinary book is to introduce students and more advanced scientists to seismic anisotropy at different scales, from the microscopic (0.1 nanometer) scale to the Earth (1000 kilometre) scale, and to improve the reader's understanding of all active Earth processes. Drawing on both mineral physics and seismology, it presents the different geological, mineralogical, and geodynamical applications of seismic anisotropy, and argues that an understanding of seismic anisotropy is necessary to interpret all seismic, geophysical, petrological, and geological data This volume is an invaluable for graduate students and research scientists in seismology/geophysics, and will be of considerable interest to geophysicists working in petroleum exploration/production and to mineral physicists and researchers in geodynamics and fluid flow in rocks. With an overview of the main recent advances in research, it also provides the perfect starting point for further research.
