Group velocity

Earth science; Seismology

Wave disturbances with a wide spectrum of periods interfere with each other producing constructive and destructive patterns. The constructive patters travel along the surface as wave packets with ...

Surface waves

Earth science; Seismology

Waves that move over the surface of the Earth. Rayleigh and Love waves are surface waves.

Preshock

Earth science; Seismology

An earthquake that occurs before the mainshock, but is not an unambiguous foreshock, either because it originated months or years before the mainshock or because it originated far from the epicentre ...

Triggered earthquake

Earth science; Seismology

An earthquake that occurs soon after or during a mainshock, but well out of the region of the aftershocks.

Leaky barrier

Earth science; Seismology

An earthquake segment boundary that is, from time to time, broken across by an earthquake.

Tsunamiogenic earthquake

Earth science; Seismology

An earthquake that generates a tsunami.

Foreshock

Earth science; Seismology

An earthquake that is smaller than, and precedes, a "mainshock". Foreshocks tend to occur in the same area as the mainshock. Foreshocks have not been observed before damaging earthquakes in British ...
