• An earthquake, in simple words, is shaking of the earth. It is a natural event.
    • It is caused due to release of energy, which generates waves that travel in all directions.
    • The point where the earthquake starts is called the focus or hypocentre of an earthquake.
    • The energy waves travelling in different directions reach the surface.
    • The point on the surface, nearest to the focus, is called epicentre. It is the first one to experience the waves.
    • It is generally, epicentre, which is shown as the location of earthquake in media and other channels.
