Open-Source MASW Inversion Tool Aimed at Shear Wave Velocity Profiling for Soil Site Explorations

Geosciences, 2020
The shear wave velocity profile is of primary interest for geological characterization of soil sites and elucidation of near-surface structures. Multichannel Analysis of Surface Waves (MASW) is a seismic exploration method for determination of near ...

Assessing the Seismic Wavefield of a Wind Turbine Using Polarization Analysis [PDF]

, 2017
Ambient seismic noise can often be seen as problematic, but with the right analysis can act as a tool to image the Earth. Wind turbines are known to generate low frequency vibrations, however, the wave types that are generated are currently unknown ...

Multichannel Analysis of Surface Waves (MASW) for the internal characterisation of the Flüela rock glacier: overcoming the limitations of seismic refraction tomography [PDF]

The Cryosphere
A multi-method geophysical campaign was carried out to characterize the subsurface of the Flüela rock glacier in Grisons, Switzerland, using electrical resistivity tomography (ERT), seismic refraction tomography (SRT), and multichannel analysis of ...

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.

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.

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.
