How to measure earthquake magnitude.
A better measure of the size of an earthquake is the amount of energy released by the earthquake, which is related to the Richter Scale by the following equation: Log E = 11.8 + 1.5 M (where Log refers to the logarithm to the base 10, E is the energy released in ergs and M the Richter magnitude).

Moment magnitude scale. The moment magnitude scale ( MMS; denoted explicitly with Mw or Mw, and generally implied with use of a single M for magnitude [1]) is a measure of an earthquake 's magnitude ("size" or strength) based on its seismic moment. It was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori.
