Abstract
As a continuation to the previous paper, wave generations from a distortional line source within the ground are studied. For a distortional origin which is of step function type in time, the displacements at several points in the ground are calculated. In contrast with the surface displacements, no displacement corresponding to the Rayleigh wave appears at deep points in the ground while three distinct pulses corresponding to the direct S, reflected S and reflected P do so.
Wave profiles at the surface are also calculated for an implosive origin. Generation mechanism of Rayleigh wave for a distortional origin is like that for a dilatational origin.
