Currently, the use of geophysical techniques to establish the shear wave velocity profile of a soil is widespread. One of these techniques is microtremor refraction, which uses ambient noise to measure the shear wave velocity (Vs), a parameter that ...

Complex anisotropy beneath the Peruvian flat slab from frequency-dependent, multiple-phase shear wave splitting analysis [PDF]
Flat or shallow subduction is a relatively widespread global occurrence, but the dynamics remain poorly understood. In particular, the interaction between flat slabs and the surrounding mantle flow has yet to be studied in detail.

Relationship between Shear Wave Velocity and SPT-N Value for Residual Soils
The shear wave velocity (Vs) is an important dynamic parameter in the field of geotechnical engineering. One of the surface wave methods is Spectral Analysis of Surface Wave (SASW) has received attention in obtaining the shear wave velocity (Vs) profile ...

The scatter of time-delays in shear-wave splitting above small earthquakes [PDF]
Measurements of time-delays in seismic shear-wave splitting above small earthquakes typically display a scatter of often as much as ±80 per cent about the mean. Changes in the average time-delay appear to be related to changes of stress, but applications

Attenuation and velocity structure in the area of Pozzuoli-Solfatara (Campi Flegrei, Italy) for the estimate of local site response [PDF]
In the present work I infer the 1D shear-wave velocity model in the volcanic area of Pozzuoli-Solfatara using the dispersion properties of both Rayleigh waves generated by artificial explosions and microtremor.

Scholte-wave dispersion analysis is effective at imaging the relatively low shear-wave velocity of shallow marine sediments in marginal seas. The combination of a four-component ocean-bottom-seismometer (OBS) and a towed air-gun source can economically ...

Establishing normal values for shear-Wave elastography of the renal cortex in healthy adults
Background: Shear-wave elastography of the kidney has emerged as a potential clinical application of this novel imaging tool. However, normal velocity values for shear-wave elastography involving the cortex of healthy kidneys have not been definitively ...

CPT-Based Shear Wave Velocity Correlation Model for Soft Soils with Graphical Assessment
Shear wave velocity is a key parameter for evaluating the mechanical properties of soils, and direct measurement is technically demanding and costly. Realizing rapid prediction by establishing correlations between other parameters and shear wave velocity

Parameter Identification for Ultrasound Shear Wave Elastography Simulation
Elasticity of soft tissue is a valuable information to physicians in treatment and diagnosis of diseases. The elastic properties of tissue can be estimated with ultrasound (US) shear wave imaging (SWEI).
