Aftershock
I'm assuming you know how earthquakes occur and all an aftershock is a smaller earthquake after a larger one. If the "aftershock" is larger than the main shock it is reclassified as the main shock and the previous "main shock" becomes a foreshock.
These are known as aftershocks.

earthquakes :)
Foreshock is what you call one of the little earthquakes that come before the big earthquake or main shock. The main shock may be followed by a little earthquake that's called the aftershock.
