signal-to-noise ratio
Earth science; Seismology
The comparison between the amplitude of the seismic signal and the amplitude of noise caused by seismic unrest and (or) the seismic instruments.
core of Earth
Earth science; Seismology
The central part of the Earth below a depth of 2900 kilometers. It is though to be composed mainly of iron and silicates and to be molten on the outside with a solid central ...
segmentation
Earth science; Seismology

mohorovicic discontinuity
Earth science; Seismology
The boundary surface or sharp seismic-velocity discontinuity (pronounced Mo-ho-ro-vi-chich) that separates the Earth's crust from the underlying mantle. Named for Andrija ...
recurrence interval
Earth science; Seismology
The approximate length of time between earthquakes in a specific seismically active area.
slip rate
Earth science; Seismology
The relative speed with which the two sides of a fault move past each other. Typically, slip rates are measured in millimeters per year. This figure applies to the motion of a ...
