Anisotropic structure of the Australian continent
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.

Temporal variation of shear-wave splitting parameters before and after the 2008 Movri Mountain earthquake in northwest Peloponnese (Greece) [PDF]
On June 8, 2008, at 12:25 GMT, a Mw 6.4 earthquake, the Movri Mountain earthquake, occurred in the area of northwest Peloponnese, western Greece. The epicenter was located in the municipality of Movri, 35 km southwest of Patras. For this study, a crustal

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

Chiral-Nematic Lattice Instability in Charge Density Wave of 1T-TiSe<sub>2</sub>. [PDF]
The charge density wave of 1T‐TiSe2 appears chiral to surface probes yet loses all symmetry in spectroscopic measurements. This study reveals how cooperative condensation of multiple phonon modes stabilizes a chiral monoclinic ground state, while a shallow nematic energy landscape allows the lattice to break the remaining symmetry at negligible cost ...

Anisotropy, focal mechanisms, and state of stress in an oilfield : passive seismic monitoring in Oman [PDF]
Knowledge of the spatial characteristics of stress and fractures in reservoirs is important for optimising production and injection processes. Serni-permanent passive microseismic monitoring is being conducted in the Yibal field, Oman, to better ...
