But I'm hypersensitive to them now, and know theyre coming before most others.

But is such a thing even possible?

Yes, yes it is.

Seismic P & S Waves

“In air, P waves take the form of sound waves and therefore move at the speed of sound, 330m/s at sea level. Some people even report hearing an earthquake (due to the higher frequency P waves vibrating or rustling objects) before they feel the S waves' arrival. Typical speeds in the Earth are faster: 1450m/s in water and 5000m/s in granite.”

The S (shear) wave causes most all the destruction.
