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.

Question

Consider the following statement about earthquake –

I Intensity of earthquakes is measured on the Mercalli Scale. I
I Magnitude of earthquake depends directly upon Amplitude of an earthquake wave. II
I Every integer on Richter Scale shows a 50 times increase in energy released Which of the statements are true?
