Theories of planetary growth via impact accretion lead to both co-accreting primitive atmospheres, as well as, to impacts of increasingly larger planetesimals. Thus, giant impacts occurred in the presence of early atmospheres. Approximating a giant impact as a sub-surface giant explosion on a fluid elastic planet, the resulting body- and surface-waves are calculated via normal-mode summation, and, the effect of the ground motion on the overlying atmosphere is calculated as a function of position. The expected convergence of anti-podal surface waves is demonstrated. Atmospheric escape for the Earth begins at 1027 J and 2x1032, 3x1032 and 3x1030 J remove 50% of the atmospheres of Earth, Venus and Mars.
