The frequency equation for Love waves propagating in an elastic layer overlying a poro-elastic solid half-space is derived. The interface between layer anf half-space is considered as loosely bonded, in general, the layer and substratum are considered under initial stress. The effects of looseness of interface and the initial stress on the phase velocity of Love waves have been studied. This is a general study and the results for welded contact at the layer-substratum interface are also discussed in the presence and absence of initial stresses in the media. It is observed that the imperfectness of the interface is effective for long wavelength waves and the phase velocity of Love waves propagating in crustal layer of the earth shows a considerable decrease with the increase in sandiness properties of the layer.
