land surface above the focus, or center of origin of an earthquake.
The location on the surface of the Earth directly above the focus, or place where an earthquake originates. An earthquake caused by a fault that offsets features on the Earth's surface may have an epicenter that does not lie on the trace of that fault on the surface. This occurs if the fault plane is not vertical and the earthquake occurs below the Earth's surface. (See Figure 1).

The point on the earth's surface vertically above the point in the crust where a seismic rupture begins.
The location where the seismic waves of an earthquake first appear on the surface, usually almost directly above the focus.
The point on the surface directly above the focus.
The position where the energy released from an earthquake first reaches the earth’s surface.
The epicenter of an earthquake is the point on a fault where an earthquake starts. Earthquakes happen because of sudden slip on a fault. The stress in the Earth's crust pushes on the fault holding it together and causing frictional resistance between the rocks on each side. Eventually enough slip is built up and the rocks slip suddenly, releasing energy in the form of sound waves and shear waves that travel through the rock to cause the shaking that we feel as the earthquakes. Your distance from the fault plane is the most important factor in determining how much shaking you feel from a particular size earthquake.
The point on the Earth's surface directly above the (subterranean) point of origin ( hypocenter) of an earthquake; only two measurements, latitude and longitude, are needed to locate it.

The epicenter or epicentre (ancient Greek: επίκεντÏον) is the point on the Earth's surface that is directly above the point where an earthquake or other underground explosion originates. The epicenter is directly above the hypocenter, the actual location of the energy released inside the earth. Seismic waves propagate spherically out from the hypocenter.
