Term Definition
Active fault
Glossaries: Earthquake geology

An active fault is a fault that has slipped during the present seismotectonic regime and is therefore likely to have renewed displacement in the future.

Synonyms: active faults, active fault
Aseismic
Glossaries: Earthquake geology

An event or process detected by geological/geophysical tools and analyses that is apparently not accompanied by earthquake activity.

Coseismic
Glossaries: Earthquake geology

An event or process detected by geological/geophysical tools and analyses that is directly associated with earthquake activity.

Synonyms: coseismic, co-seismic, Co-seismic
Depth min and max
Glossaries: Earthquake geology

The depth range that includes the location of the causative (i.e., seismogenic) fault of an earthquake – either a particular one or an expected/forecasted one – within the crust (or below, depending on cases).

Synonyms: min depth, max depth
Dip
Glossaries: Earthquake geology

The angle by which a fault is more or less steep from the top towards the bottom.

Fault scarp
Glossaries: Earthquake geology

The brittle result of a fault that ruptures the ground-surface.

Synonyms: fault scarp, Fault scarps, fault scarps
Historical seismicity
Glossaries: Earthquake geology

The historical record of ca. pre-XXth century earthquakes that have been parameterized in specific historical catalogues.

Instrumental seismicity
Glossaries: Earthquake geology

The recent and ongoing record of earthquakes that have occurred since the availability of modern-era seismometers (i.e., since the XXth century).

Synonyms: instrumental seismicity
Interseismic
Glossaries: Earthquake geology

An event or process possibly detected by geological/geophysical tools and analyses that occurs between two significant earthquakes.

Recurrence interval
Glossaries: Earthquake geology

The average time span between two comparably large earthquakes on a particular seismogenic fault.

Seismogenic fault
Glossaries: Earthquake geology

The brittle tectonic element either causative of a particular seismic event/mainshock(s) of a given sequence, or deemed potentially responsible for a future one.

Synonyms: Seismogenic source, seismogenic fault, seismogenic source
