Download scientific diagram | (a) 6-C hodograms showing the translational (displacement) and rotational (rotation angle) polarization of pure-mode waves inside the medium (black) and at the free surface (red). Shown are a P-wave and an SV-wave, both propagating in the x-direction (φ = 0 • ) at an inclination of θ = 20 • , and a Rayleigh wave (φ = 0 • and ξ = π/8). Note that at the free surface, all three waves exhibit rotational motions. Inside the medium, the P-wave motion is limited to translational motion. (b) Hodograms for the same three waves after converting the displacements to rotation angles by applying the temporal derivative and scaling by the slowness (e.g. 1 = ˙ u x p s , and 5 = ω y ). As a scaling slowness we used the real shear-wave slowness p s = 1/β. Note that the P-and S-waves are now both rectilinearly polarized. Only the Rayleigh wave preserves an elliptical polarization. from publication: 6-C polarization analysis using point measurements of translational and rotational ground-motion: Theory and applications | We provide a six component (6-C) polarization model for P-, SV-, SH-, Rayleigh-, and Love-waves both inside an elastic medium as well as at the free surface. It is shown that single-station 6-C data comprised of three components of rotational motion and three components of | Polarization, Ground Motion and Waves | ResearchGate, the professional network for scientists.
