280396 VO MA PE 04 VO Anisotropy (NPI) (2020W)

The students are expected to understand the main principles of seismic wave propagation in anisotropic media, the occurence of seismic anisotropy within the Earth, and the main applications in this field.

The course covers the following topics:
Wave propagation in homogeneous anisotropic media, elastic anisotropy of minerals, polycrystalline rocks, Backus-, Reuss and other averages over anisotropic properties, transverse isotropy, effects at seismic wavelength, effects of seismic anisotropy on the different wave type: refraction, shear-wave splitting, surface waves (azimuthal anisotropy, radial anisotropy), anisotropy in the Earth, upper crust, lower crust, mantle, inner core, different tectonic environments, mountain chains, subduction zones, cracked media, Hudson-models, crack density, anisotropy effects in reflection seismic, applications in the hydrocarbon industry, relation with stress, reservoir engineering.

The students will also learn present scientific material in a presentation.

The course consists mostly of lectures.
