Define and distinguish between the following: epicenter, focus, foreshock, aftershock

The subsurface area where the motion of seismic waves is initiated along a fault plane is the focus (or hypocenter). The area at the surface directly above the focus is the epicenter. A foreshock is a quake that precedes the main shock. An aftershock occurs after the main shock, sharing the same general area of the epicenter.
