rotate

Earth science; Seismology

Changing the orientation or angle of a seismogram to the true radial or transverse directions.

spectral acceleration

Earth science; Seismology

Commonly refers to either the Fourier amplitude spectrum of ground acceleration or the PSRV.

filtering

Earth science; Seismology

Attenuation of certain frequency components of a seismic signal and the amplification of others. For a recorded signal, the process can be accomplished electronically or numerically in a digital ...

low-velocity zone

Earth science; Seismology

Any layer in the Earth in which seismic wave velocities are lower than in the layers above and below.

earthquake hazard

Earth science; Seismology

Any physical phenomenon associated with an earthquake that may produce adverse effects on human activities. This includes surface faulting, ground shaking, landslides, liquefaction, tectonic ...

stochastic

Earth science; Seismology

Applied to processes that have random characteristics.

A somewhat poorly understood process; involves the slipping of a fault located in the same region as, but not directly associated with, a fault which ruptures in a major earthquake. Most likely, the ...
