Deep Azimuthal Seismic Anisotropy in the Westernanatolia and Aegean Subduction Zone
Shear wave splitting due to source-side mantle anisotropy is estimated from broadband teleseismic and local S waves using a suite of Aegean subduction zone events. The data have been recorded by Kandilli Observatory and Earthquake Research Institute (KOERI) stations, at the depth of more than 30 km, from 2000 to 2007. We assume that there are at most two anisotropic regions along the ray path: ...
متن کاملGlobal azimuthal anisotropy in the transition zone.
Surface wave dispersion measurements for Love wave overtones carry evidence of azimuthal anisotropy in the transition zone of Earth's mantle (400 to 660 kilometers deep). A Backus-Gilbert inversion of anisotropic phase velocity maps, with resolution kernels mainly sensitive to the transition zone, shows a robust long-wavelength azimuthally anisotropic velocity structure. This observation puts n...
متن کاملAnisotropy and Flow in Pacific Subduction Zone Back-arcs
We have obtained constraints on the strength and orientation of anisotropy in the mantle beneath the Tonga, southern Kuril, Japan, and Izu-Bonin subduction zones using shear-wave splitting in S phases from local earthquakes and in teleseismic core phases such as SKS. The observed splitting in all four subduction zones is consistent with a model in which the lower transition zone (520–660 km) an...
متن کاملSubduction zone rheology
Rheological flow laws can be obtained from studies using multi-anvil high-pressure systems with synchrotron-based piezometers and strain metrics. The high flux X-ray source provides minute-scale time resolution with accurate measurement of diffraction patterns and direct sample images. Measurements of length changes with an accuracy of one part in 104 are being developed and will provide a new ...
متن کاملThe subduction zone flow field from seismic anisotropy: a global view.
Although the morphologies of subducting slabs have been relatively well characterized, the character of the mantle flow field that accompanies subduction remains poorly understood. To analyze this pattern of flow, we compiled observations of seismic anisotropy, as manifested by shear wave splitting. Data from 13 subduction zones reveal systematic variations in both mantle-wedge and subslab anis...
