Well, maybe not. P-waves ("compression waves") tend to get absorbed by
liquid, like what is present in the outer core of the Earth. Since we
are talking about a seismic source that is situated directly antipodal to
the observer's locality, the P-wave would have to go through the core.
Instead, it would have been dissipated by the creamy liquid-filled
center, never to reach the antipode.

Since S-waves take a different route to the antipode, this scenario still
Ummm.... Liquid-filled centers. Ummmm....
