Fig. 11. SKS waves observed at HRV for 4 different backaziumths, A) SSE, 2) WNW, 3) NNW and 4) NNE. (Left) Observed radial (top row) and transverse (3rd row) horizontal component seismograms. The significant energy observed on the transverse component is an effect of the seismic anisotropy. Corrected radial (2nd row) and transverse (bottom row) component seismograms, where the effect of propagation through the anisotropic medium has been removed. (Right) Particle motion diagrams (top) before and (bottom) after correction. Note that the energy on the transverse component has been greatly reduced, and the particle motion made significantly more linear, indicating that the splitting parameters have been correctly calculated.
