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 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 epicenter or epicentre (ancient Greek: ÎµÏ€Î¯ÎºÎµÎ½Ï„ÏÎ¿Î½) 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.
A focal point or origin of activity. Used in relation to poltergeist phenomena where a single person, unconsciously projecting strong negative energies, may be creating the poltergeist activity through psychokinesis.
