The point of origin of an earthquake *inside* the Earth is known as the focus or hypocenter. Earthquake waves (seismic waves) radiate outwards from this point.
The Focus (or Hypocenter) is the actual point within the Earth’s crust where an earthquake originates, due to the rupture of rocks along a fault line. The energy released at the focus propagates as seismic waves.
