Love waves due to a point source in an isotropic elastic medium under initial stress

Abstract

The propagation of Love type waves due to a point source in an isotropic inhomogeneous medium under initial stress has been investigated in this paper. Firstly, the propagation of Love waves in a homogeneous crust overlying an inhomogeneous substratum, both under compressive initial stress, due to the presence of a point source in the interface has been considered. Finally, the case in which the upper layer is inhomogeneous and the lower medium is homogeneous has been discussed. The Green's function technique developed by Ghosh (1963) has been used to solve the problem.
