Shear Wave Splitting and Mantle Flow Beneath Alaska
Journal of Geophysical Research: Solid Earth, 2020 Shear wave splitting is often assumed to be caused by mantle flow or preexisting lithospheric fabrics. We present 2,389 new SKS shear wave splitting observations from 384 broadband stations deployed in Alaska from January 2010 to August 2017.

Seismic anisotropy beneath the Chinese Mainland: Constraints from shear wave splitting analyses
Earthquake Research Advances, 2021 We use earthquakes recorded by the China National Seismic Network from 2015 to 2019 and measure shear wave splitting parameters of SKS to study the anisotropic characteristics beneath the mainland of China.

Comment on “SKS splitting beneath continental rifts zones” by Gao et al. [PDF]
, 1999 International audienceAs previously suggested by many authors, shear wave splitting rneasurernents certainly provide the best insights on the tectonic structure (or fabric) of the upper mantle.

Deriving micro- to macro-scale seismic velocities from ice-core c axis orientations [PDF]
The Cryosphere, 2018 One of the great challenges in glaciology is the ability to estimate the bulk ice anisotropy in ice sheets and glaciers, which is needed to improve our understanding of ice-sheet dynamics.

Seismic anisotropy and shear-wave splitting in lower-crustal and upper-mantle rocks from the Ivrea Zone : experimental and calculated data [PDF]
, 1996 International audienceTo quantify the relationships between anisotropy. S-wave splitting and tectonics, we determined the seismic properties of lower-crustal and upper-mantle rocks outcropping in the lvrea Zone (Northem Italy).

Cejing jishu, 2023 The wave field data which is monitored the fracturing crack by micro seismic in the well is complex, especially when the shear wave (S-wave) encounters the fracture. The shear wave will split into the fast or slow wave. The polarization directions of the

Apparent Splitting of S Waves Propagating Through an Isotropic Lowermost Mantle [PDF]
, 2018 Observations of shear wave anisotropy are key for understanding the mineralogical structure and flow in the mantle. Several researchers have reported the presence of seismic anisotropy in the lowermost 150–250 km of the mantle (i.e., D urn:x-wiley:jgrb ...

, 2020 Observations of seismic anisotropy in the lowermost mantle—D″—are abundant. As seismic anisotropy is known to develop as a response to plastic flow in the mantle, constraining lowermost mantle anisotropy allows us to better understand mantle dynamics ...
