A Correct answer
Explanation

The Richter scale is a logarithmic scale that measures the magnitude (total energy released) of an earthquake. It's different from the Mercalli scale which measures destruction/damage. Candela measures light intensity and Fahrenheit measures temperature - both are unrelated to earthquakes.
