threshold
Earth science; Seismology
The smallest size of explosion that can be detected as an explosion.
gaussian noise spectrum
Earth science; Seismology
The spectrum of a time history whose sample values are generated by random selection from a statistical population that has a specified mean and standard deviation. The values (ordinates) have a ...
rupture velocity
Earth science; Seismology
The speed at which a rupture front propagates during an earthquake.
wave dispersion
Earth science; Seismology
The spreading out of a wave train due to each wave length traveling at its own velocity.
dispersion
Earth science; Seismology
The spreading out of a wave train due to each wavelength travelling with its own velocity.
standard deviation
Earth science; Seismology
The square root of the arithmetic mean of the squared deviations from the mean (the square root of the variance; see variance).
shear stress
Earth science; Seismology
The stress component parallel to a given surface, such as a fault plane, that results from forces applied parallel to the surface or from remote forces transmitted through the surrounding rock.
