Effects of Background Porosity on Seismic Anisotropy in Fractured Rocks: An Experimental Study
Applied Sciences, 2023 Fractures are widely distributed in the subsurface and are crucial for hydrocarbon, CCS, offshore infrastructure (windfarms), and geothermal seismic surveys.

Sensitivity of shear wave splitting to fracture connectivity [PDF]
Geophysical 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.

Anisotropic structure of the Australian continent
Frontiers 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]
Songklanakarin 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]
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

Full‐wave effects on shear wave splitting [PDF]
Geophysical Research Letters, 2014 AbstractSeismic anisotropy in the mantle plays an important role in our understanding of the Earth's internal dynamics, and shear wave splitting has always been a key observable in the investigation of seismic anisotropy. To date the interpretation of shear wave splitting in terms of anisotropy has been largely based on ray‐theoretical modeling of a ...
