The exact transient closed-form solutions for suddenly applied force or dislocation (displacement-jump), such as a crack or fault which travels at a constant velocity and a constant depth below the surface of an elastic half plane, are obtained in this study. The numerical results are shown for the various cases as follows. In the case of vertical downward line load, the retrograde particle rotation exists at the arrived point of Rayleigh wave, but in the case of upward vertical load, the direction of the rotation coincides with wave propagational direction. In the supersonic case, responses of the surface became in the opposite direction compared with subsonic case, and in inverse relation to moving velocity. In addition to these, the stress near the tip of moving dislocation, the response to both side extensional dislocation etc. are shown graphically.
