Energy ratio between two earthquakes is the relative amount of seismic energy released by one earthquake compared to another, typically calculated from the difference in their magnitudes on scales such as the moment magnitude or related scales.

| \( E_1 \) = Energy of Earthquake 1 | \( ft \cdot lbf\) | \(J\) |
| \( E_1 \) = Energy of Earthquake 1 | \( ft \cdot lbf\) | \(J\) |
| \( M_1 \) = Magnitude of Earthquake 1 | \(dimensionless\) | \(dimensionless\) |
| \( M_1 \) = Magnitude of Earthquake 2 | \(dimensionless\) | \(dimensionless\) |
