Seismology
Coda
Earth science; Seismology
The concluding train of seismic waves that follows the principal part of an earthquake.
Kernel
Earth science; Seismology
The complete seismogram Green's function for each of the moment tensor elements. They are obtained by summing the normal modes of the Earth. Used in calculating centroid moment tensors.
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.
