Earthquake Magnitude Comparison Calculator

The magnitude is the quantified measure of the earthquake size and is measured using a seismometer. It can be derived from the logarithm of the maximum displacement or amplitude of the earthquake. A measurement scale used to measure the earthquake magnitude is the Richter Scale, which was developed by the seismologists Charles Francis Richter and Beno Gutenberg. Use this online Richter Scale Comparison calculator to find the difference of two earthquake magnitudes and measure which how bigger is a magnitude than the other.

d=10(m-n) Where, d = Difference between two Magnitudes (Richters) m = Maximum Magnitude (Richters) n = Minimum Magnitude (Richters)


What is the magnitude difference of two earthquakes with richter scale measure of 7.3 and 6.0?

Difference = 10 (7.3 - 6.0)
         = 10(1.3)
         = 19.9526
Hence, a 7.3 magnitude earthquake is 19.95 times bigger than 6.0 .
