Shear‐wave splitting beneath the Galápagos archipelago [PDF]
Geophysical Research Letters, 2005 Shear‐wave splitting measurements in the Galápagos archipelago show a rapid change from consistently oriented anisotropy to no measurable anisotropy. At the western edge of the archipelago delay times are 0.4–0.9 s and fast polarization directions are 81–109°E. These directions are consistent with anisotropy resulting from shear of the asthenosphere by

Automated shear-wave splitting analysis for single- and multi- layer anisotropic media
Seismica, 2023 Shear-wave velocity anisotropy is present throughout the earth. The strength and orientation of anisotropy can be observed by shear-wave splitting (birefringence) accumulated between earthquake sources and receivers. Seismic deployments are getting ever

The scatter of time-delays in shear-wave splitting above small earthquakes [PDF]
, 2004 Measurements of time-delays in seismic shear-wave splitting above small earthquakes typically display a scatter of often as much as ±80 per cent about the mean. Changes in the average time-delay appear to be related to changes of stress, but applications

Stress-dependent shear wave splitting and permeability in fractured porous rock
Journal of Rock Mechanics and Geotechnical Engineering, 2019 It is well known that shear wave propagates slower across than parallel to a fracture, and as a result, a travelling shear wave splits into two directions when it encounters a fracture.

Complex anisotropy beneath the Peruvian flat slab from frequency-dependent, multiple-phase shear wave splitting analysis [PDF]
, 2013 Flat or shallow subduction is a relatively widespread global occurrence, but the dynamics remain poorly understood. In particular, the interaction between flat slabs and the surrounding mantle flow has yet to be studied in detail.

Experimental observation of water saturation effects on shear wave splitting in synthetic rock with fractures aligned at oblique angles [PDF]
, 2015 Fractured rocks are known to exhibit seismic anisotropy and shear wave splitting (SWS). SWS is commonly used for fractured rock characterization and has been shown to be sensitive to fluid type. The presence of partial liquid/gas saturation is also known

Shear-wave splitting in the mantle of the pacific [PDF]
Geophysical Journal International, 1994 SUMMARY The bulk of previously known data on seismic anisotropy in the suboceanic mantle was obtained from observations of azimuthal variations of the surface-wave and P, velocities. Our study of azimuthal anisotropy in the mantle of the Pacific is based on observations of shear-wave splitting. The idea of our method of measurement (Vinnik & Farra 1992)
