SplitLab: A shear-wave splitting environment in Matlab [PDF]

open access: yesComputers and Geosciences, 2008
We present a graphical user interface to facilitate the processing of teleseismic shear-wave splitting observations. In contrast to a fully automated technique, we present a manual, per-event approach that maintains user control during the sequence of processing.

Shear-Wave Splitting Analysis Using Optimization Algorithms [PDF]

open access: yesLithosphere, 2022
Shear-wave splitting (SWS) analysis is used to predict fractures in subsurface media. Specifically, two parameters relevant to SWS analysis (the azimuth of the fast shear wave and the time delay between the fast and slow shear waves) are used to quantify

New shear wave splitting measurements using broadband seismic data recorded by the BX seismological network in Botswana [PDF]

open access: yesData in Brief, 2023
New measurements shear-wave splitting (SWS) were determined using a teleseismic dataset from 21 broadband seismic stations belonging to the GSN-BX network in Botswana archived at IRIS-DMC.

Teleseismic shear wave splitting measurements in noisyenvironments [PDF]

open access: yesGeophysical Journal International, 1999
SUMMARY High noise levels hamper teleseismic shear wave splitting measurements, which bandpass filtering does not always help. To investigate how robust splitting measurements are to noise, we analysed a set of synthetic records with known splitting parameters and added fixed levels of noise.

Robust Phase Association and Simultaneous Arrival Picking for Downhole Microseismic Data Using Constrained Dynamic Time Warping [PDF]

open access: yesSensors
Accurate phase association and arrival time picking are pivotal for reliable microseismic event location and source characterization. However, the complexity of downhole microseismic wavefields, arising from heterogeneous subsurface structures, variable ...

Full‐wave effects on shear wave splitting [PDF]

open access: yesGeophysical Research Letters, 2014
AbstractSeismic anisotropy in the mantle plays an important role in our understanding of the Earth's internal dynamics, and shear wave splitting has always been a key observable in the investigation of seismic anisotropy. To date the interpretation of shear wave splitting in terms of anisotropy has been largely based on ray‐theoretical modeling of a ...

Shear-Wave Splitting in a Critical Crust: the Next Step Biréfringence des ondes transversales dans les croûtes critiques : la prochaine étape

open access: yesOil & Gas Science and Technology, 2006
Arguably, shear-wave splitting displaying azimuthal anisotropy has not lived up to its initial promise of opening a new window for understanding cracks and stress in the crust.
