face to be felt on earth's surface
The abbreviation for primary waves is P-waves.
P waves (APEX)
For P waves, the two descriptive words are Primary (or compressional) waves, while for S waves, the two words are Secondary (or shear) waves.
Primary (P) waves : Primary waves, the fastest wave sent , come from the focus not the epicenter. (S) waves : Secondary waves, the second fastest wave sent out by an earthquake, it comes from the focus also.
P-waves, or primary waves, are the fastest seismic waves and typically arrive at the surface first after an earthquake. These waves can travel through both solid and liquid materials, making them the first to be detected by seismographs.

P waves (APEX)
Primary waves (P-waves) are the fastest seismic waves and are the first to be detected after an earthquake. They are able to travel through solid rock, liquid, and gas, making them the fastest seismic waves.
