Automation of Shear-Wave Splitting Measurements using Cluster Analysis

  title={Automation of Shear-Wave Splitting Measurements using Cluster Analysis},
  author={Nicholas A Teanby and J Kendall and Mirko van der Baan},
The propagation of two orthogonally polarized shear waves, or shearwave splitting, is arguably the most robust indication of seismic anisotropy in the Earth. This splitting can be parameterized in terms of the polarization of the fast shear-wave and the lag time between fast and slow components dt. These two parameters provide constraints on the mechanism causing the anisotropy. All methods of calculating splitting require a shear-wave analysis window to be selected. Then the and dt that best… CONTINUE READING
