Hypocenter - Wikipedia
An earthquake's hypocenter or focus is the position where the strain energy stored in the rock is first released, marking the point where the fault begins to rupture. [3] This occurs directly beneath the epicenter , at a distance known as the hypocentral depth or focal depth .

Focus (Hypocenter): The point within the Earth where an earthquake rupture starts. This post is part of Exploring Earthquakes, a rich collection of resources co-presented by the California Academy of Sciences and KQED. This material is also available as a free iBooks textbook and iTunes U course.
The Science of Earthquakes | U.S. Geological Survey - USGS.gov
The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter. Sometimes an earthquake has foreshocks .
Epicenter and Focus (hypocenter) of an Earthquake - IRIS
Epicenter is the location on the surface of the Earth directly above where the earthquake starts. Focus (aka Hypocenter) is the location in the Earth where the earthquake starts.
Difference Between Epicenter and Hypocenter
May 1, 2020 · The epicenter is the point on Earth’s surface directly above where an earthquake occurs along a fault. The hypocenter is the actual point at which the earthquake occurs along a fault beneath Earth’s surface.
Earthquake Hypocenter - an overview | ScienceDirect Topics
An earthquake hypocenter refers to the point within the Earth where the rupture of rocks originates, leading to the initiation of seismic waves. AI generated definition based on: Encyclopedia of Physical Science and Technology (Third Edition), 2003
The region of initiation of seismic energy within the Earth during an earthquake is the focus or hypocenter (Figure 2). This is the initial region along which a new fault forms or an old fault ruptures. From the focus, slip along the fault spreads quickly.
4.3: Measuring and Locating Earthquakes - Geosciences LibreTexts
The focus, also called a hypocenter of an earthquake, is the point of initial breaking or rupturing where the displacement of rocks occurs. The focus is always at some depth below the ground surface in the crust, and not at the surface.
Hypocenter - Simple English Wikipedia, the free encyclopedia
The hypocenter (literally: 'below the center') is the site of an earthquake or a nuclear explosion. In an earthquake, it is a synonym of the focus and is directly below the epicenter . [ 1 ] In the case of a nuclear explosion, it is a synonym of ground zero .
Epicenter, Hypocenter - SpringerLink
Jan 1, 2014 · The hypocenter of an earthquake is the subsurface location at which energy stored along a locked fault is first released. The epicenter is that location at the surface, which is closest to the hypocenter.
