Aftershock
by Frederic P. Miller (Editor), McBrewster John (Editor) and Agnes F. Vandome (Editor)
An aftershock is a smaller earthquake that occurs after a previous large earthquake in the same area (the main shock). If an aftershock is larger than the main shock, the aftershock is redesignated as the main shock and the original main shock is redesignated as a foreshock. Aftershocks are smaller earthquakes formed as the crust around the displaced fault plane adjusts to the effects of the main shock.
