What is it about?
In unconsolidated granular media, the state of stress has a major effect on the elastic properties and wave velocities. Effective media modeling of granular packs shows that a vertically oriented uniaxial state of stress induces vertical transverse isotropy (VTI), characterized by five independent elastic parameters. We present an anisotropic Rayleigh wave inversion that solves for in situ elastic moduli of unconsolidated dry sands at very low effective stress.

Why is it important?
Using anisotropic Rayleigh wave inversion allows us to solve for four out of the five elastic constants of a VTI media. Based on the inversion results we can determine the degree of anisotropy and estimate the stress regime.
Perspectives
This is my first paper and it was a great experience. So far we have only done isotropic surface wave inversion and I hope that with this paper we are embarking on a new path.
