Shear-Wave Splitting in the Alpine Region [PDF]

open access: yesGeophysical Journal International, 2021
<p>To constrain seismic anisotropy under and around the Alps in Europe, we study SKS shear-wave splitting from the region densely covered by the AlpArray seismic network. We apply a technique based on measuring the splitting intensity, constraining well both the fast orientation and the splitting delay.

Sensitivity of shear wave splitting to fracture connectivity [PDF]

open access: yesGeophysical Journal International, 2023
SUMMARY Shear wave splitting (SWS) is currently considered to be the most robust seismic attribute to characterize fractures in geological formations. Despite its importance, the influence of fluid pressure communication between connected fractures on SWS remains largely unexplored.

Reviews on seismic anisotropy based on shear-wave splitting in the Tibetan Plateau

open access: yes地球与行星物理论评, 2021
The research on the anisotropy of shear wave splitting in the Tibetan Plateau has been carried out for nearly 30 years, and important progress has been made in theoretical methods and practical applications. A large number of shear wave splitting results

Effects of Background Porosity on Seismic Anisotropy in Fractured Rocks: An Experimental Study

open access: yesApplied Sciences, 2023
Fractures are widely distributed in the subsurface and are crucial for hydrocarbon, CCS, offshore infrastructure (windfarms), and geothermal seismic surveys.

Anisotropy Variations in the Alaska Subduction Zone Based on Shear‐Wave Splitting From Intraslab Earthquakes

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Shear‐wave splitting observations can provide insight into mantle flow, due to the link between the deformation of mantle rocks and their direction‐dependent seismic wave velocities.

Anisotropic structure of the Australian continent

open access: yesFrontiers in Earth Science, 2023
The Australian continent preserves some of the oldest lithosphere on Earth in the Yilgarn, Pilbara, and Gawler Cratons. In this study we present shear wave splitting and Ps receiver function results at long running stations across the continent.

Seismic anisotropy of the upper mantle beneath Thailand: Tectonic setting constrained by shear-wave splitting analysis [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2020
The tectonic setting of the lithosphere and upper mantle underneath Thailand varies and changes substantially over short distances. We have mapped these variations using shear wave splitting (SWS) analysis.

Shear‐wave splitting beneath the Galápagos archipelago [PDF]

open access: yesGeophysical 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

Diurnal expansion and contraction of englacial fracture networks revealed by seismic shear wave splitting

open access: yesCommunications Earth & Environment, 2021
Daily variations in seismic S-wave anisotropy reveal the dynamic response of englacial fractures to changing meltwater supply, according to shear wave splitting measurements from a seismometer network on the Rhonegletscher, Switzerland.
