The original "body-wave magnitude" – mB or m B (uppercase "B") – was developed by Gutenberg (1945b, 1945c) and Gutenberg & Richter (1956) [2] to overcome the distance and magnitude limitations of the M L scale inherent in the use of surface waves. mB is based on the P- and S-waves, measured over a longer period, and does not saturate until ...
Body wave may refer to one of the following: Body wave (seismology), a type of seismic wave; Body wave (dance move) Body wave (hair style) Body wave (locomotion ...

A seismic wave is a mechanical wave of acoustic energy that travels through the Earth or another planetary body. It can result from an earthquake (or generally, a quake ), volcanic eruption , magma movement, a large landslide and a large man-made explosion that produces low-frequency acoustic energy.
A P wave (primary wave or pressure wave) is one of the two main types of elastic body waves, called seismic waves in seismology. P waves travel faster than other seismic waves and hence are the first signal from an earthquake to arrive at any affected location or at a seismograph .
Dispersive body waves is an important aspect of seismic theory. When a wave propagates through subsurface materials both energy dissipation and velocity dispersion takes place. Energy dissipation is frequency dependent and causes decreased resolution of the seismic images when recorded in seismic prospecting. The attendant dispersion is a ...
These are of lower resolution than P wave models, due to the distances involved and fewer bounce-phase data available. S waves can also be used in conjunction with P waves for differential arrival time models. Surface waves can be used for tomography of the crust and upper mantle where no body wave (P and S) data are available. Both Rayleigh ...
Seismology (/ s aɪ z ˈ m ɒ l ə dʒ i, s aɪ s-/; from Ancient Greek σεισμός (seismós) meaning "earthquake" and -λογία (-logía) meaning "study of") is the scientific study of earthquakes (or generally, quakes) and the generation and propagation of elastic waves through planetary bodies.
