Some countries prefer Richter scale to Mercalli. Richter scale, a logarithmic base-10 scale that defines magnitude is the logarithm for the ratio between the amplitude seismic waves and an arbitrarily small amplitude.
Below is a comparison of the Richter Scale and Mercalli.
Richter Scale = Mercalli equivalent
I
3.5 = II
4.2 = III
4.5 = IV
4.8 = V
VI = 5.4
6.1 = VII
6.5 = VIII
6.9 = IX
7.3 = X
8.1 = XI
andgt; 8.1 = XII
