Observations of Azimuthal Anisotropy in Prestack Seismic Data*
A method for displaying prestack seismic data that highlights azimuthal anisotropy is shown. Observations of azimuthal anisotropy in prestack seismic data using this and other methods make it clear that azimuthal anisotropy is observed in all types of seismic data, land, marine and multicomponent and it is widespread, from the shallowest to the deepest reflectors. Consequently, anisotropy must ...
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 کاملVariable azimuthal anisotropy in Earth's lowermost mantle.
A persistent reversal in the expected polarity of the initiation of vertically polarized shear waves that graze the D'' layer (the layer at the boundary between the outer core and the lower mantle of Earth) in some regions starts at the arrival time of horizontally polarized shear waves. Full waveform modeling of the split shear waves for paths beneath the Caribbean requires azimuthal anisotrop...
متن کاملImage-guided WEMVA for azimuthal anisotropy
Azimuthal anisotropy is common in layered basins with strong folding and fracturing effects. Traditional processing on individual azimuths usually yields images with inconsistent depths. In this paper, we propose to use an image obtained from one azimuth to constrain the image-space velocity analysis on other azimuths. This method directly tackles the differences in anisotropic parameters among...
