The primary output is a 2D shear-wave velocity (Vs) cross section with a maximum depth approximately half the receiver array length (e.g., 0.3 m). Secondary cross sections are also generated using the Vs data as the main parameter. Young’s and shear modulus values are calculated by using the theoretical equations that also use density (shear modulus) and Poisson’s ratio (Young’s modulus), both of which contribute only partially (e.g., < 3%). Usually, a density of 2300 kg/m3 and a Poisson’s ratio of 0.35 are used for these calculations.
Empirical conversions are used to generate density and Poisson’s ratio cross sections from Vs cross section.
