Ambient noise tomography for wavespeed and anisotropy in the crust of southwestern China
… and Vsh Their differences are measured as radial anisotropy. We then conduct Eikonal tomography to study azimuthal anisotropy in the crust. Our tomography results are well consistent with geology in the study region. In the Sichuan Basin, low wavespeed and positive radial anisotropy (Vsh> Vsv) in …

Seismic attenuation of regional phases in the northern Middle East and the Tibetan Plateau
… can be applied in earthquake hazard studies. Azimuthal anisotropy of Q has been observed, which is probably related to focusing/defocusing or crustal anisotropy. Intrinsic attenuation could be isolated by solving the inverse problems involving the effects of azimuthal anisotropy and …

LATERALLY HETEROGENEOUS SEISMIC ANISOTROPY INVESTIGATED BY SHEAR WAVE SPLITTING ANALYSES
… geophysical studies suggest that seismic anisotropy is a nearly ubiquitous property of the Earth’s crust and upper mantle. In this study, we utilize the shear wave splitting technique to investigate the piercing-point-dependent azimuthal anisotropy beneath the northeastern edge of the …

MANTLE FLOW AND TRANSITION ZONE DISCONTINUITIES BENEATH THE CARRIBEAN PLATE: CONSTRAINTS FROM SHEAR WAVE SPLITTING AND RECEIVER FUNCTION ANALYSES
<p>"Azimuthal anisotropy quantified by teleseismic SKS, SKKS, PKS (“XKS”) and local S wave splitting parameters is used to investigate lithospheric deformation and asthenospheric flow beneath the boundary zone of the North American and Caribbean plates and adjacent areas. A total of 4915 XKS and …

Inversion of azimuthal velocity and amplitude variations for seismic anisotropy
… causes the seismic wavefield to exhibit azimuthal anisotropy. The best way known to detect fractures, at large scales, is by recognizing the effect of them on seismic data in attempt of inversing it. The Altamont-Bluebell play is within the Uinta Basin in northeast Utah, and is considered …

Processing of DAS and geophone VSP data from the CaMI Field Research Station
… three different surveys: a walk around VSP for azimuthal anisotropy analysis, zero offset VSPs to test the emerging DAS technology and walk-away VSP to obtain imaging results for straight and helical wounded fibre optic cables. From the azimuthal analysis, the fast direction was identified to …

Fluctuating Open Heavy Flavour Energy Loss in a Strongly Coupled Plasma with Observables from RHIC and the LHC
… of the v2(pT ) for B-mesons describing the azimuthal anisotropy at √ sNN = 2.76 TeV for central collisions and √ sNN = 5.5 TeV for central, semi-central and peripheral collisions.

Crustal structure beneath hi-climb seismic array in western Tibetan plateau from a generalized H-κ method
… are complex and uncertain, like crustal anisotropy and dipping crust. Recently, H-κ method with harmonic corrections, which corrects both Ps and crustal multiples by including crustal azimuthal anisotropy and dipping interfaces for multiple layers, was developed by Jiangtao Li, Xiaodong …

Ambient noise interferometry and surface-wave array tomography in southeastern Tibet
… due to uneven noise energy distribution, and azimuthally anisotropic phase velocity maps. With phase velocity dispersion measurements at periods 10 - 150 s from 1 year data of 75 broad band stations in SE Tibet, we performed inversion for wavespeed variations and azimuthal anisotropy. The …

Statistical hadronization phenomenology in heavy ion collisions at SPS and RHIC energies
… freeze-out dynamics. We suggest resonances and azimuthal anisotropy as experimental probes for this task.

Teleseismic imaging of the Slave craton and implications for the assembly of cratonic lithosphere
… wave phase velocity, shear wave velocity, and azimuthal anisotropy of the Slave cratonic lithosphere. The tomographic images reveal high shear wave velocities associated with a particularly depleted, cold, and unperturbed Archean cratonic lithosphere. Furthermore, the inversions reveal distinct …

Estimating Seismic Anisotropy: Fluid Substitution Theory, 3D-Printed Inclusion Models, and Multi-Component 3D VSP in the Bakken Shale
Understanding seismic anisotropy is one of the most important issues in seismic exploration. In this dissertation, I tried to understand how fluids and lithology influence the elastic properties and seismic anisotropy of rocks, theoretically, experimentally, and in the field. I derived anisotropic …

Stress prediction, fracture detection, and multiple attribute analysis of seismic attributes in a Barnett Shale gas reservoir, Fort Worth Basin, Texas
… stress conditions and natural fractures. Azimuthal interval velocity analysis was found to be an effective tool for the detection of changing stress fields. The analysis of azimuthal amplitude data suggests that it can be used to map changes in azimuthal anisotropy with higher spatial …
