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.

Finite-Frequency SKS Splitting: Measurement and Sensitivity Kernels [PDF]
, 2008 Splitting of SKS waves caused by anisotropy may be analyzed by measuring the splitting intensity, i.e., the amplitude of the transverse signal relative to the radial signal in the SKS time window. This quantity is simply related to structural parameters.

The Turkish Dilatancy Project (TDP3): multidisciplinary studies of a potential earthquake source region [PDF]
, 1987 The section of the North Anatolian Fault lying near the city of Izmit, at the east of the Marmara Sea, has been identified as a seismic gap and the possible site of a future major earthquake.

The development of magmatism along the Cameroon Volcanic Line: evidence from seismicity and seismic anisotropy [PDF]
, 2014 The Cameroon Volcanic Line (CVL) straddles the continent-ocean boundary in West Africa but exhibits no clear age progression. This renders it difficult to explain by traditional plume/plate motion hypotheses; thus, there remains no consensus on the ...

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.

Observations of stress relaxation before earthquakes [PDF]
, 2004 Theory and observations suggest that seismic shear wave splitting, caused by fluid-saturated stress-aligned microcracks, directly monitors low-level deformation before fracturing, faulting and earthquakes occur.

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
