{wiki=P-wave_modulus}
The P-wave modulus, often referred to as the P-wave velocity or compressional wave modulus, is a measure of the elastic response of a material to compressional waves (also known as P-waves or primary waves), which are a type of seismic wave. P-waves are the fastest seismic waves and travel through solids, liquids, and gases by compressing and expanding the material in the direction of wave propagation.
