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.

Shear Wave Splitting and Mantle Flow Beneath Alaska
Journal of Geophysical Research: Solid Earth, 2020 AbstractShear 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. In Alaska, splitting appears to be controlled by the absolute plate motion (APM) of the North American ...

Identifying global seismic anisotropy patterns by correlating shear-wave splitting and surface-wave data [PDF]
Physics of the Earth and Planetary Interiors, 2009 International audienceWe compare a global compilation of shear-wave splitting measurements with azimuthal seismic anisotropy parameters inferred from surface-wave tomography.

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

Journal of Geophysical Research: Solid Earth, 2022 Shear‐wave splitting measurements are commonly used to resolve seismic anisotropy in both the upper and lowermost mantle. Typically, such techniques are applied to SmKS phases that have reflected (m‐1) times off the underside of the core‐mantle boundary ...

Wave-equation shear wave splitting tomography [PDF]
Geophysical Journal International, 2008 The main focus of this paper is the development of a theoretical framework for the tomographic inversion of (broad-band) shear wave splitting measurements in terms of anisotropic structure in the upper mantle. We show that the partial differential equations (PDEs) that govern wave equation shearwave splitting tomography are, upon linearization with ...

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.
