Seismology

Active fault

Earth science; Seismology

A fault along which slip has occurred in recent geological time, or where earthquake foci are located.

Aliasing

Earth science; Seismology

A phenomena where frequencies are overlapping each other, and the the individual contributions from those frequencies are unable to be deciphered. This is avoided by decreasing the sampling interval ...

Oceanic spreading ridge

Earth science; Seismology

A fracture zone along the ocean bottom that accommodates upwelling of mantle material to the surface, thus creating new crust. This fracture is topographically marked by a line of ridges that form ...

Auxiliary fault-plane

Earth science; Seismology

A plane orthogonal to the fault plane.

Station

Earth science; Seismology

A ground position at which a geophysical instrument is located for an observation.

Seismic discontinuity

Earth science; Seismology

A surface or thin layer within layer the Earth across which P-wave and/or S-wave velocities changes rapidly.

Fault-bend fold

Earth science; Seismology

A fold within the hanging wall block of a fault, formed by bending of the hanging block as it slips over a nonplanar fault surface.
