The place in the Earth's crust where stress is released during an earthquake is called the focus or hypocenter. It is the point underground where the rupture of the fault occurs and energy is released in the form of seismic waves. This is the actual source of an earthquake.

Focus or Hypocenter
This is known as the earthquake's focus or hypocentre.
In geological terms, it is the point below the Earth's surface where seismic waves originate during an earthquake.
An earthquake's Focus is located directly under the Epicenter of an earthquake. The Epicenterof an earthquake is located on the surface of the earthquake.
The Richter scale expresses the relative magnitude of an earthquake, which is a measure of the energy released at the focus of an earthquake.
