The epicenter (/ ˈ ɛ p ɪ ˌ s ɛ n t ər /), epicentre, or epicentrum in seismology is the point on the Earth's surface directly above a hypocenter or focus, the point where an earthquake or an underground explosion originates.
Epicentre is the point on the surface of the Earth that is directly above the focus of an earthquake, where fault rupture begins. Learn how to locate the epicentre using seismic waves and arcs, and what are aftershocks and their effects.

Learn what causes earthquakes, how they are recorded and measured, and what is the epicenter and hypocenter of an earthquake. The epicenter is the location on the surface directly above the hypocenter, which is the location below the earth's surface where the earthquake starts.
Sep 11, 2019 · The place on the Earth’s surface directly above the focus is called the epicenter (Figure 13.2). Earthquake foci may be shallow (less than 70 km from Earth’s surface) to deep (greater than 300 km deep), though shallow to intermediate depths are much more common.
The point on a fault within earth’s crust where the fracturing begins and most slippage occurs is called the focus of the earthquake. Another name for it is the hypocenter. The point on the earth’s surface directly above the focus is the epicenter.
More shaking is usually the result of more seismic energy released. The epicenter is the location on the Earth’s surface vertically above the point of rupture (focus). The epicenter is also the location that most news reports give because it is the center of the area where people are affected.
Earthquake - Magnitude, Seismology, Epicenter: Earthquake magnitude is a measure of the “size,” or amplitude, of the seismic waves generated by an earthquake source and recorded by seismographs. (The types and nature of these waves are described in the section Seismic waves.)
