Anisotropy in the deep Earth
B Romanowicz, HR Wenk - Physics of the Earth and Planetary Interiors, 2017 - Elsevier
Seismic anisotropy has been found in many regions of the Earth's interior. Its presence in the
Earth's crust has been known since the 19th century, and is due in part to the alignment of …
