Seismic anisotropy beneath the Chinese Mainland: Constraints from shear wave splitting analyses
Earthquake Research Advances, 2021 We use earthquakes recorded by the China National Seismic Network from 2015 to 2019 and measure shear wave splitting parameters of SKS to study the anisotropic characteristics beneath the mainland of China.

Deformation in Rutford Ice Stream, West Antarctica: measuring shear-wave anisotropy from icequakes [PDF]
, 2013 Ice streams provide major drainage pathways for the Antarctic ice sheet. The stress distribution and style of flow in such ice streams produce elastic and rheological anisotropy, which informs ice-flow modelling as to how ice masses respond to external

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.

New “Fresnel‐Zone” estimates for shear‐wave splitting observations from finite‐difference modeling
Geophysical Research Letters, 2000 We employ full finite‐difference modeling to study effects of teleseismic shear‐wave splitting in 2D upper‐mantle models with lateral variations of anisotropy. In our models the anisotropy is confined to a layer at variable depth within the top 550 km of

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

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.

Shear‐wave splitting observations across southwest Ireland [PDF]
Geophysical Research Letters, 2006 Shear‐wave splitting analyses have been carried out on teleseismic data from the southwest of Ireland acquired during the Irish Seismological Lithospheric Experiment (ISLE). The data were gathered over a ten‐month period by a temporary network of 23 broadband and short‐period stations.

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.

Upper crust anisotropy of the 2020 Jiashi MS 6.4 earthquake
Frontiers in Earth Science, 2023 The 2020 Jiashi MS 6.4 earthquake occurred north of the 1997–1998 Jiashi earthquake swarm. Because of its complex tectonic environment and frequent strong earthquake occurrence, scholars have paid extensive attention to this area.

Poloidal‐ and Toroidal‐Mode Mantle Flows Underneath the Cascadia Subduction Zone
Geophysical Research Letters, 2020 Several hypotheses have been proposed to explain intriguing circular shear wave splitting patterns in the Pacific Northwest, invoking either 2‐D entrained flows or 3‐D return flows. Here, we present some hitherto unidentified, depth‐dependent anisotropic
