Seismology

eigenvalue

Earth science; Seismology

In tensor mathematics, it represents the values of the matrix in a principal coordinate system.

elastic dislocation theory

Earth science; Seismology

In seismology, a theoretical description of how an elastic Earth responds to fault slip, as represented by a distribution of displacement discontinuities.

filter

Earth science; Seismology

In seismology, a physical system or a mathematical operation that changes the waveform or amplitude of a signal.

spectrum

Earth science; Seismology

In seismology, a curve showing amplitude and phase as a function of frequency or period.

In reference to earthquake shaking, velocity is the time rate of change of ground displacement of a reference point during the passage of earthquake seismic waves commonly expressed in centimeters ...

aseismic front

Earth science; Seismology

In a subduction zone, the boundary between the seismogenic foerearc basin and the aseismic volcanic arc.

compressional (P) axis

Earth science; Seismology

In a double-couple system, the dipole that is directed toward the source and lies in the quadrants of dilatation. The ground is being pushed toward the source, giving dilatational first P-waves at ...
