Seismology
Seismic gap
Earth science; Seismology
A segment of an active fault zone that has not experienced a major earthquake during a time interval when most other segments of the zone have. Seismologists commonly consider seismic gaps to have a ...
Fault barrier
Earth science; Seismology
An area of fault surface that is resistant to slip because of geometrical or structural changes.
Fault-angle depression
Earth science; Seismology
An arrow, downdropped crustal block bounced by a fault on only one side.
Deterministic hazard assessment
Earth science; Seismology
An assessment that specifies single-valued parameters such as maximum earthquake magnitude or peak ground acceleration, without consideration of likelihood.
Microearthquake
Earth science; Seismology
A term used to describe earthquakes under Richter magnitude 2, and occasionally, slightly larger quakes, especially those not felt by people nearby.
Gravity wave
Earth science; Seismology
A type of wave where gravity is the main restoring force in the system. Tsunami's are the most prevalent type of gravity wave.
Accelerograph
Earth science; Seismology
A type of seismograph used to measure ground acceleration as a function of time.
