Seismology
focal depth of earthquakes
Earth science; Seismology
The depth of the focus below the surface of the Earth.
holocene
Earth science; Seismology
The current geological time period that started about 10,000 years ago.
plates and plate tectonics
Earth science; Seismology
The crust and upper mantle of the earth are made up of about a dozen large plates and several smaller ones that are constantly moving. The movements are very slow - only a few centimetres per year. ...
eigenfunction
Earth science; Seismology
The corresponding displacement patterns of the eigenfrequencies (also called normal modes). When the solution is zero with the given boundary conditions, that is the fundamental mode. Higher values ...
Fourier spectra
Earth science; Seismology
The corresponding amplitude and phase signals resulting from the Fourier transform of a time series.
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.
