Entry: P wave
URI: https://registry.epos-eu.org/ncl/FAIR-Incubator/tcs-SEISMO/61
A symbol for a seismic body wave that involves particle motion (alternating compression and dilatation) in the direction of propagation. P waves travel faster than S waves and, therefore, arrive earlier in the record of a seismic event (P stands for 'unda prima' = primary wave). The particle displacement associated with P waves (for a classical linear elastic continuum in an isotropic far field) is parallel to the direction of wave propagation. For this reason, P waves are sometimes called longitudinal waves. In isotropic media, the curl of the Pwave field (i.e., rotational motion) is zero. However, this is not so in general, for instance, for anisotropic or Cosserat continua
