Aftershocks are smaller earthquakes following the mainshock. They typically occur on or near the rupture plane of the mainshock, resulting from changes of stress and frictional properties of the fault zone caused by the mainshock. The duration of aftershock sequences is typically a few years for earthquakes at plate boundaries, but can last much longer within stable continental interiors.
