The paper investigates the dispersion of G-type seismic waves along the interface of dry sandy and inhomogeneous isotropic elastic media. The maximum energy flow which projects the fact that a large amount of energy can flow along the interface for horizontally polarized shear wave with group velocity lesser than the shear wave velocity in the upper mantle has been shown in closed form by means of dispersion equation. Effect of sandiness parameter and inhomogeneities on phase velocity has been shown in graphs. A case study has also been made for isotropic homogeneous over an inhomogeneous half-space
