About the Math: The energy released by an earthquake is related to its Richter scale magnitude (M) by the formula: log₁₀(E) = 4.8 + 1.5M, where E is the energy in Joules. Because of the 1.5 multiplier, each step of 1.0 on the Richter scale corresponds to a 31.62× increase in the energy released (since 101.5 ≈ 31.62). One ton of TNT is standardized as releasing 4.184 × 109 Joules of energy.
