Seismology
Isostasy
Earth science; Seismology
The way in which the lithosphere "floats" on the asthenosphere. There are two models generally accepted, the Airy model which is load "floating" in the asthenosphere with a root sinking down with ...
Residual
Earth science; Seismology
The difference between the measured and predicted values of some quantity.
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.
