Seismology

moho

Earth science; Seismology

A discontinuity in seismic velocity that marks the boundary between the Earth's crust and mantle. Also termed the Mohorovicic' discontinuity, after the Croatian seismologist Andrija Mohorovicic' ...

A mass that moves with oscillating motion under the influence of external forces and one or more forces that restore the mass to its stable at-rest position. In earthquake engineering, an oscillator ...

green's function

Earth science; Seismology

A mathematical representation that, in reference to earthquake shaking, is used to represent the ground motion caused by instantaneous slip on a small part of a fault. Green's functions can be ...

swarm

Earth science; Seismology

A series of minor earthquakes, none of which may be identified as the mainshock, occurring in a limited area and time.

tsunami magnitude (Mt)

Earth science; Seismology

A number used to compare sizes of tsunamis generated by different earthquakes and calculated from the logarithm of the maximum amplitude of the tsunami wave measured by a tide gauge distant from the ...

orthogonal function

Earth science; Seismology

A set of functions where the integral of the product of two different functions over a specified interval is always zero. Examples include Bessel functions and Legendre functions.
