Summary
The structure of the earth varies in 3-dimensions superimposed on the dominant trend of increase of seismic wavespeed with depth.We consider integral representations of the wavefield for media with horizontal variations, and from these develop the concepts of reflection and transmission operators that allow insight gained in the discussion of stratified media to be transferred to a more general 3-D environment.This operator approach also provides a convenient link between larger scale seismology and seismic reflection studies., and also helps in assessing approximations for propagation of both body waves and surface waves
