An aftershock is an earthquake that occurs after a previous earthquake, the mainshock. Rapid changes of stress between rocks, and the stress from the original earthquake are the main causes of these aftershocks,<ref name=Britannica>{{Cite web|title=Aftershock {{!}} geology|url=https://www.britannica.com/science/aftershock-geology|access-date=2021-10-13|website=Encyclopædia Britannica|archive-date=2015-08-23|archive-url=https://web.archive.org/web/20150823124854/https://www.britannica.com/science/aftershock-geology|url-status=live}}</ref> along with the crust around the ruptured [[Fault (geology)|fault plane]] as it adjusts to the effects of the mainshock.<ref name="WAAFEC" /> An aftershock is in the same region as the main shock but always of a smaller magnitude, however, they can still be powerful enough to cause even more damage to buildings that were already previously damaged from the mainshock.<ref name=Britannica/> If an aftershock is larger than the mainshock, the aftershock is redesignated as the mainshock and the original main shock is redesignated as a [[foreshock]]. Aftershocks are formed as the crust around the displaced [[Fault (geology)|fault plane]] adjusts to the effects of the mainshock.<ref name=WAAFEC/>
