Primary surface rupture

Earth science; Seismology

Surface rupture that is directly connected to subsurface displacement on a seismic fault.

Structures whose ongoing performance during an emergency is required or whose failure could threaten many lives. May include (1) structures such as nuclear power reactors or large dams whose failure ...

Lifelines

Earth science; Seismology

Structures that are important or critical for urban functionality. Examples are roadways, pipelines, power lines, sewers, communications, and port facilities.

Nyquist frequency

Earth science; Seismology

The highest angular frequency found in the spectra of digital data used to avoid aliasing (see aliasing).

Source function

Earth science; Seismology

The ground motion generated at the fault during rupture, usually as predicted by a theoretical model and represented by a time history or spectrum. The terms Brune spectrum, Aki spectrum, and Haskel ...
