Shear-wave splitting measurements — Problems and solutions
Tectonophysics, 2008Abstract We compare sensitivity and reliability of three basic techniques of shear-wave splitting analysis – cross-correlation of wave components, minimization of covariance matrix eigenvalues and minimizing energy on the transverse component – of both synthetic and real data, point out some problems and propose solutions.

Bootstrapping shear-wave splitting errors
Bulletin of the Seismological Society of America, 1994Abstract We have developed a bootstrap method to estimate errors associated with inverting SKS waveforms for shear-wave splitting parameters. Although presented for shear-wave splitting inversions, this method is suitable for any waveform inversion procedure.

Null Detection in Shear-Wave Splitting Measurements
Bulletin of the Seismological Society of America, 2007Shear-wave splitting measurements are widely used to analyze orien- tations of anisotropy. We compare two different shear-wave splitting techniques, which are generally assumed to give similar results. Using a synthetic test, which covers the whole backazimuthal range, we find characteristic differences, however, in fast-axis and delay-time estimates ...

Making Reliable Shear-Wave Splitting Measurements
Bulletin of the Seismological Society of America, 2013Shear-wave splitting (SWS) analysis using SKS, SKKS, and PKS (here- after collectively called XKS) phases is one of the most commonly used techniques in structural seismology. In spite of the apparent simplicity in performing SWS measure- ments, large discrepancies in published SWS parameters (fast direction and splitting time) suggest that a ...

Thin layers and shear‐wave splitting
GEOPHYSICS, 1991The near‐surface weathering layer is considered by many to be strongly anisotropic. Any shear‐wave signal passing through this low‐velocity layer will inherit, to some degree, the anisotropic response of this layer. For thin weathering layers, information about previous anisotropic events may be distorted; when the thickness of this layer approaches ...

Shear-wave splitting in compliant rocks
The Leading Edge, 2010Shear-wave splitting is a phenomenon that has received a lot of attention primarily because of its connection with vertically aligned cracks or fractures within reservoirs. However, in most cases the largest amount of shear-wave splitting is observed to occur in the near-surface layers where the rocks are the least consolidated, and so are least likely
