Research progress on layered seismic anisotropy - A review

open access: yesEarthquake Research Advances, 2021
Seismic anisotropy is an effective feature to study the inner structure of the Earth. In complex tectonic area, the assumption of single-layer anisotropy is sometimes not well consistent with the observed data; thus, the assumption of multi-layered (i.e.

Upper- and mid-mantle interaction between the Samoan plume and the Tonga-Kermadec slabs [PDF]

open access: yes, 2016
Mantle plumes are thought to play a key role in transferring heat from the core\u2013mantle boundary to the lithosphere, where it can significantly influence plate tectonics. On impinging on the lithosphere at spreading ridges or in intra-plate settings,

Seismic gravity-gradient noise in interferometric gravitational-wave detectors [PDF]

open access: yes, 1998
When ambient seismic waves pass near and under an interferometric gravitational-wave detector, they induce density perturbations in the Earth, which in turn produce fluctuating gravitational forces on the interferometer’s test masses.

Ab initio study of the elastic behavior of MgSiO3 ilmenite at high pressure [PDF]

open access: yes, 2002
We investigate the athermal high pressure behavior of the elastic properties of MgSiO3 ilmenite up to 30 GPa using the ab initio pseudopotential method. Our results at zero pressure are in good agreement with single-crystal elasticity measurements.

Automated shear-wave splitting analysis for single- and multi- layer anisotropic media

open access: yesSeismica, 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

Traveltime and conversion-point computations and parameter estimation in layered, anisotropic media by tau-p transform [PDF]

open access: yes, 2003
Anisotropy influences many aspects of seismic wave propagation and, therefore, has implications for conventional processing schemes. It also holds information about the nature of the medium.

Lateral variations in the crustal structure of the Indo-Eurasian collision zone [PDF]

open access: yes, 2018
We thank Michael Ritzwoller and two anonymous reviewers for constructive comments that have helped improve the manuscript. The majority of the seismic data used in this study were downloaded from IRIS DMC.

Seismic Anisotropy—Introduction [PDF]

open access: yesGeophysics, 2011
This special section is dedicated to seismic anisotropy, which is playing an increasingly more important role in our understanding and modelling of the subsurface. Most papers published in this section were presented at the 14th International Workshop on Seismic Anisotropy (IWSA), which was held on 12–16 April 2010 in Hillarys, Perth, Western Australia.

Confronting Solid‐State Shear Bias: Magmatic Fabric Contribution to Crustal Seismic Anisotropy

open access: yesGeophysical Research Letters, 2023
Seismic anisotropy is controlled by aligned rock‐forming minerals, which most studies attribute to solid‐state shear with less consideration for magmatic fabric in plutonic rocks (rigid‐body rotation of crystals in the presence of melt).
