Seismology
Point source
Earth science; Seismology
An approximation used in describing the waves radiated from a seismic source.
Least-squares fit
Earth science; Seismology
An approximation of a set of data with a curve such that the sum of the squares of the differences between the observed points and the assumed curve is a minimum.
Receiver function
Earth science; Seismology
A time series calculated from teleseismic P wavetrains that can be interpreted in terms of reflections and transmissions of mode-converted waves at discrete boundaries beneath the recording station. ...
Plate tectonics
Earth science; Seismology
A theory supported by a wide range of evidence that considers the Earth's crust and upper mantle to be composed of several large, thin, relatively rigid plates that move relative to one another. ...
Blind thrust
Earth science; Seismology
A deep crustal thrust-fault with no or only indirect surface expression such as a fold structure.
Zonal harmonics
Earth science; Seismology
Used to describe Earth's normal modes using Legendre polynomials. The Zonal harmonics represents the lowest order of the polynomial where the number of great circles through the pole with zero ...
