The magnitude R of an earthquake is related to the energy it releases by a logarithmic scale, R=a ₁₀ (E / E₀ ) , where a and E₀ are positive constants. An earthquake of magnitude R=6 has 31 times more energy than one of R=5 . An earthquake of magnitude R=7 has times more energy than one of R=5 , where is approximately
