Spectral amplification

Earth science; Seismology

A measure of the relative shaking response of different geologic materials. The ratio of the Fourier amplitude spectrum of a seismogram recorded on one material to that computed from a seismogram ...

A set of parameters built into the physics of the recording instrument. These are well known and can be removed from a seismogram by deconvolution of the transfer function and the seismic signal to ...

Earthquake swarm

Earth science; Seismology

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

Tsunami

Earth science; Seismology

(Japanese for "Harbour Wave"). A series of huge ocean waves caused by a rapid, large-scale disturbance of the sea water, such as a major earthquake beneath the seabed that causes large vertical ...

Fault scarp

Earth science; Seismology

A slope formed by the offset of the surface of the Earth by a fault.

Tectonic plate

Earth science; Seismology

A large, relatively rigid segment of the Earth's lithosphere that moves in relation to other plates over the deeper interior. Plates meet in convergence zones and separate at divergence zones.
