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 ...

Mantle flow through a tear in the Nazca slab inferred from shear wave splitting
Geophysical Research Letters, 2017 A tear in the subducting Nazca slab is located between the end of the Pampean flat slab and normally subducting oceanic lithosphere. Tomographic studies suggest mantle material flows through this opening.

Mantle Flow Pattern Associated With the Patagonian Slab Window Determined From Azimuthal Anisotropy
Geophysical Research Letters, 2022 Geological processes in Southern Patagonia are affected by the Patagonian slab window, formed by the subduction of the Chile Ridge and subsequent northward migration of the Chile Triple Junction.

The Turkish Dilatancy Project (TDP3): multidisciplinary studies of a potential earthquake source region [PDF]
, 1987 The section of the North Anatolian Fault lying near the city of Izmit, at the east of the Marmara Sea, has been identified as a seismic gap and the possible site of a future major earthquake.

Sub-slab mantle anisotropy beneath south-central Chile [PDF]
, 2012 Knowledge of mantle flow in convergent margins is crucial to unravelling both the contemporary geodynamics and the past evolution of subduction zones. By analysing shear-wave splitting in both teleseismic and local arrivals, we can determine the relative
