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 part.
segmentation
Earth science; Seismology
The braking of faults along their lengths by other faults that cross them or their limitations in length by other factors such as topography or bends in the strikes of the faults. Segmentation can ...
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 Mohorovicic, the Croatian ...
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 fault over an extended ...
earthquake occurrence interval
Earth science; Seismology
