The motion of edge dislocations and slip on fault planes are important mechanisms involving sub and through-surface slip. Here exact solutions for largely arbitrary in-plane slip in a half plane along zones normal to the surface are derived and the general wave-front pattern described. For two examples of finite zones of uniform slip, the displacements on the free surface of the half plane are examined. In the case of the slip zone passing through the half-plane surface, separate and prominent systems of surface waves are seen to be generated at the surface-zone intersection point. Data illustrating this and other behavior is presented.
