The intensity of an earthquake is measured on two scales (i) Richter scale (ii) Mercalli scale. The intensity of an earthquake is the measurement of energy released. The Richter scale has a shaking amplitude 10 times that of the previous integer and shows an increase of 32 times in energy. Energy equal to 6 ounces of TNT is released by an earthquake of a magnitude of 1.
