Geological age of a deposit or event, defined with reference to the International Stratigraphic Chart Ages are often expressed using the units 'ka' or 'Ma'.

Geological age of the youngest deposits that have been subject to deformation in the Neotectonic period [Neotectonics database field]

Elongate terrace(s) usually lying parallel to and above a river channel and its floodplain. Alluvial terraces consist of a relatively level strip of land, called a "tread", separated from an [..]

The nearest region, city or town and country for the epicentre of a teleseismic (distant) earthquake. The nearest city, town or general locality and state for a local (Australian) earthquake.

The UTC time (Coordinated Universal Time) at which an earthquake wave arrives and is recorded on the seismogram at a seismic station.

Average strike or azimuth (in degrees from north) of the surface trace of a structure. In the Neotectonics Database we express the strike of a structure using the right-hand rule, whereby an azimuthal [..]

Bearing given in degrees clockwise from North. For example, Southwest corresponds to azimuth 225°. Bibliographic references Bibliographic reference(s) relating to a neotectonic feature. May contain pu [..]

A thrust fault that does not rupture all the way to the ground surface. Movement along the fault produces uplift in the form of an anticlinal fold, but a clear or continuous surface rupture is not rec [..]

An earthquake wave that travels within the Earth, sometimes going through its deep interior, P and S waves are body waves.

Bandpass filters describe the upper and lower limits of desired frequency ranges. The Butterworth filter type used in seismic processing produces a ripple free signal with smooth cutoffs.
