\nThe 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.
\n<\/section>\n
\nThe 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.
\n<\/section>\n
\nThe Epicentre is the point on the Earth’s surface located directly above the focus. It is usually where the earthquake shaking is strongest and damage is often greatest. A Seismic Zone is an area where earthquakes are known to occur frequently. Photosphere is the visible surface of the Sun.
