Earthquake Scales

Overview

Engineering reference data for Earthquake Scales in miscellaneous.

Key Formulas

Unit Conversion

$y = x \cdot k$

Multiply by conversion factor.

Linear Interpolation

$y = y_1 + \frac{(x - x_1)(y_2 - y_1)}{x_2 - x_1}$

Estimate between two known points.

Percentage

$p = \frac{\text{part}}{\text{whole}} \times 100\%$

Part as fraction of whole.

Variables

Earthquake Scale Comparison

The following table compares three common earthquake measurement scales. Note that these scales measure different aspects of seismic activity and are not directly convertible.
