Multimode Rayleigh wave profiling by hybrid surface and borehole methods [PDF]
, 2014 To improve the accuracy of shallow seismic shear wave velocity profiling, we propose a minimally invasive hybrid surface-and-borehole method that enhances the detection of higher modes of Rayleigh wave dispersion data.

Identifying recharge under subtle ephemeral features in a flat-lying semi-arid region using a combined geophysical approach [PDF]
Hydrology and Earth System Sciences, 2020 Identifying and quantifying recharge processes linked to ephemeral surface water features is challenging due to their episodic nature. We use a combination of well-established near-surface geophysical methods to provide evidence of a surface and ...

Retrieving shallow shear-wave velocity profiles from 2D seismic-reflection data with severely aliased surface waves [PDF]
, 2019 The inversion of surface-wave phase-velocity dispersion curves provides a reliable method to derive near-surface shear-wave velocity profiles. In this work, we invert phase-velocity dispersion curves estimated from 2D seismic-reflection data.

Finite-Frequency SKS Splitting: Measurement and Sensitivity Kernels [PDF]
, 2008 Splitting of SKS waves caused by anisotropy may be analyzed by measuring the splitting intensity, i.e., the amplitude of the transverse signal relative to the radial signal in the SKS time window. This quantity is simply related to structural parameters.

Some practical applications of shear wave velocity measurements in dense sand [PDF]
E3S Web of ConferencesShear wave velocity (Vs) profiles were obtained using two techniques at a dense sand site in Blessington near Dublin, Ireland. It was shown that both the multichannel analysis of surface waves (MASW) and seismic CPT (SCPTU) techniques provided reliable ...
