Seismology

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.

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 ...

aftershock

Earth science; Seismology

An earthquake that occurs after a "mainshock" (or larger earthquake). Aftershocks occur in the same general region as the "mainshock" and result from readjustments of stress at places along the fault ...

great circle path

Earth science; Seismology

An arc on the Earth's surface that represents the path that seismic energy has traveled to get from the source to the receiver.

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 ...
