A primary, or compression, body seismic wave that travels through the depth of the earth.
Primary seismic waves. The fastest set of earthquake vibrations. They move through the Earth in compression and expansion motions (much like sound waves move through air). Called primary because they are the first recorded at a seismograph. Primary waves are able to travel through both solids and liquids.
A seismic wave that involved particle motion in the direction of propagation; the p stands for primary because this wave arrives first.
The primary, or fastest traveling wave moving away from a seismic event, characterized by compressional vibration.
a wave in which particle motion is in the direction of source propagation. Also called compressional wave, primary wave, pressure wave, and longitudinal wave.
An elastic body wave in which particles move in the direction of propagation. It is the wave assumed in most seismic surveys. Also called primary or push-pull wave.
seismic wave that moves material in push-pull fashion in the direction of its travel. This type of seismic wave can travel through solids, liquids, and gases. Also called a primary wave.
A longitudinal shock wave, produced by fracture of rocks at the focus of an earthquake. They travel faster than S-waves.
The fastest of seismic waves, and thus the first to arrive at a location following an earthquake (the P stands for "primary"). This is a compressional body wave; particle movement is parallel to the direction of propagation of the wave. Its speed is 5.5 to 7.2 km/sec in the crust and 7.8 to 8.5 km/sec in the upper mantle.
A compression wave produced by an earthquake. The "P" is from the Italian "primero," indicating that the P-waves were the first to arrive at seismic stations.
The primary or fastest wave traveling away from a seismic event through the earths crust, and consisting of a train of compressions and dilations of the material; see Seismic Wave.
Of the two types of elastic body waves (named because they travel through the body of the Earth) that are produced by earthquakes and recorded by seismometers. The name primary comes from the fact that they have the highest velocity of all seismic waves and are thus the first to arrive at any seismic station, the other body wave type being S- or secondary waves. Sound, as a pressure wave and a longitudinal wave, is also a P-wave.
