The effect of crack orientation on the nonlinear interaction of a P wave with an S wave by J. A. TenCate, A. E. Malcolm, X. Feng, M. C. Fehler

“…We measure the nonlinear response via the traveltime delay induced in a low‐amplitude P wave probe by a high‐amplitude S wave pump. We find evidence that crack orientation has a significant effect on the nonlinear signal.…”

Shear-wave Velocity Structure of Greenland from Rayleigh-wave Analysis by V. Corchete

“…Later, all seismic events (and some stations) were grouped to obtain a dispersion curve for each source-station path. These dispersion curves were regionalized and inverted according to the generalized inversion theory, to obtain shear-wave velocity models for a rectangular grid of 16x20 points. …”

Shear-wave velocity structure of Australia from Rayleigh-wave analysis by Víctor Corchete

“…Later, all seismic events (and some stations) were grouped to obtain a dispersion curve for each source-station path. These dispersion curves were regionalized and inverted according to the generalized inversion theory, to obtain shear-wave velocity models for a rectangular grid of 2.5º×2.5º mesh size. …”
