Record 3 2004-10-22

English

Subject field(s)
  • Vulcanology and Seismology
  • Geophysics
  • Surveillance, Detection and Reconnaissance (Military)
DEF

That type of seismic body wave that involves particle motion (alternating compression and expansion) in the direction of propagation.

OBS

The fastest of seismic waves, these compressional waves are the first recorded by the seismographs and have a cycle of about one second. These are higher frequency body waves that are felt by humans and cause damage.

OBS

compressional wave; longitudinal wave; primary; P-Wave: terms extracted from the "Disarmament and Peace Keeping" glossary with the permission of the United Nations Office at Geneva.

French

Domaine(s)
  • Volcanologie et sismologie
  • Géophysique
  • Surveillance, détection et reconnaissance (Militaire)
DEF

Ondes de compression qui se propagent très rapidement et apparaissent les premières sur les enregistrements.

OBS

onde longitudinale; onde de compression; onde primaire; onde P : termes tirés du lexique «Désarmement et Maintien de la Paix» avec l'autorisation de l'Office des Nations Unies à Genève.

Spanish

Campo(s) temático(s)
  • Vulcanología y sismología
  • Geofísica
  • Vigilancia, detección y reconocimiento (Militar)
DEF

Onda sísmica primaria, de propagación rápida en cualquier medio sólido o fluido.
