Development of Deep Shear Wave Velocity Profiles and an Approach to Generate Site Signature Consistent Pseudo Shear Wave Velocity Profiles in the Mississippi Embayment
… technique to generate deep shear wave velocity profiles (VS profiles), applying this technique at 24 sites across the Mississippi embayment and developing an approach to generate pseudo site signature consistent VS profiles from velocity functions and fundamental frequency. In the presented SWM …

Improving resolution of stiff layers in soil profiles through multi-step inversion of Sasw data
… layers commonly encountered in desert soil profiles significantly affect the soil load capacity and load distribution pattern. The purpose of this research is to develop algorithms for detecting stiff layers through inversion of seismic surface wave data to generate one-dimensional shear …

Shallow 3D Shear Wave Velocity Model and Revised Site Period Prediction Map for the Mexico City Basin
… predicted values to the measured site period and Vs profiles to validate the results. Critiques and discussion on the deficiencies for both predictors were also included for transparency. Overall, the results from both predictors were determined to give accurate results, but the uncertainty in the …

Elasticity of single-crystal iron-bearing pyrope to 20 GPa and 750 K
… a significant contribution to seismic Vp and Vs anisotropy in the upper mantle. Together with the elasticity of olivine and pyroxene minerals in the upper mantle, we have constructed new velocity profiles for two representative compositional models, pyrolite and piclogite, along Earth’s upper …

Nonlinear site amplification functions for Central and Eastern North America
… in soil properties at individual sites. Site profiles are developed for 1,747,278 site response analyses, 582,426 each of linear elastic, equivalent linear and nonlinear 1-D analyses for 70,650 unique site profiles. The database of simulations is the largest of its kind. This study describes …

Vertical Motions at the Fringes of the Icelandic Plume
… Rayleigh wave dispersion data to obtain crustal VS profiles at each station. Both inverse- and guided forward modelling techniques are employed, as well as a Bayesian, trans-dimensional algorithm. Moho depths thus obtained are combined with seismic wide-angle and deep reflection data to produce a …

1D shallow sedimentary subsurface imaging using ambient noise and active seismic data
… improving the resolution of the estimated 1D Vs profile. Second, the new theoretical approach based on the Diffuse Field Assumption (DFA) is used for the interpretation of the observed microtremors H/V spectral ratio. The theory is further extended in this research work to include not only the …
