Epicenter.
Concerning earthquakes, the Epicentre is the point on the land surface immediately above the focus of the quake. The Focus is the actual point within the Earth where the quake occurred.
The epicenter is the point on the Earth's surface directly above the hypocenter (100's of miles), the hypocenter is where movement first occurs in the fault, and the epicenter is where we feel the quake (when it's its strongest).
The parts of an earthquake are as follows:First there are body waves, which are seismic waves that travel in the ground, originating from the focus, or the starting point of the earthquake.Above the body waves, just under the earth's surface, travel the slower-moving surface waves. This is what shakes the ground violently and causes humans to feel the quake's intensity.When the quake is over, aftershock occurs; a tremor or a small quake following a large one.Finally, there may be a landslide.
"Epicenter" usually refers to a point on the Earth's surface directly above the "focus" of an earthquake. When a quake occurs, a seismic monitoring station can determine how far away it was from the shock wave pattern -- that is called the "epicentral distance" -- but not the exact direction. But with three or more monitoring stations' epicentral distances, one can draw intersecting circles to pinpoint the exact location.
The name given to the point where an earthquake begins is the "focus" or "hypocenter." This is the location within the Earth where the seismic energy is first released, leading to the generation of seismic waves that cause shaking felt at the surface.

They are both words that re used to describe the origin of an earthquake. More specifically the focus is the point within the earth where the fault rupture and initial movement occur. The epicentre is the point on the Earth's surface directly above this.
The epicentre of an earthquake is the point on the Earth's surface directly above the point within the Earth where the earthquake actually occurred (known as the focus or hypocentre). From this point on the surface the waves of the earthquake radiate outward like the ripples in a pond when a stone is thrown in.
The epicenter is the point on the earth's surface vertically above the focus of an earthquake. It is as close to the point of origin of the quake as you can get on the surface. The earthquake is strongest at that point.
The focus is below ground that is where the earth quake happens. The epicenter is above because that is where it is located
Epicenter is used in the field of earth quakes. Epicenter means the spot where the earth quake occured or where the effects were felt the strongest

An earthquake is the shaking of the ground caused by a sudden release of energy in the Earth's crust, while the epicenter is the point on the Earth's surface directly above where the earthquake originated. The strength of an earthquake is measured by its magnitude, which is not related to the location of the epicenter.
they used the focus
The epicenter of an earthquake is the point on the Earth's surface above the focus or hypocenter which is the point within the Earth where the rupture occurs. As such the epicentre is the closest point to this and the seismic waves have had to travel through the smallest amount of material and so have undergone the least amount of attenuation (in this case attenuation is a reduction in amplitude of the seismic waves due to energy being lost by their movement or propagation through the Earth). However there can be some exceptions to this and please see the related questions for more information.
