Calculation

  1. 1Formula: lgE = 4.8 + 1.5M (Joules)
  2. 2E(M₁) = 10^(4.8+1.5×6) = 63.1 TJ
  3. 3E(M₂) = 10^(4.8+1.5×7) = 1,995.3 TJ
  4. 4Ratio = 10^(1.5×1.0) ≈ 31.62x
Each 1.0 magnitude step ≈ 31.6× energy; 2.0 steps ≈ 1000×. Magnitude measures released energy while intensity describes local shaking. Moment magnitude (Mw) matches Richter at large magnitudes.
