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.
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 ...
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 ...
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.
