- Measuring the seismic moment allows for the development of a more uniform, scientific scale of an earthquake’s relative size based on classical mechanics, called moment magnitude (MW). MW can be determined by using the following formula: MW = 2/3log M0 – 10.7www.britannica.com/science/moment-magnitude

Moment magnitude scale - Wikipedia
The moment magnitude scale (MMS; denoted explicitly with M or Mw or Mwg, and generally implied with use of a single M for magnitude ) is a measure of an earthquake's magnitude ("size" or strength) based on its seismic moment. Mw was defined in a 1979 paper by Thomas C. Hanks and Hiroo … See more
Richter scale: the original measure of earthquake magnitude
At the beginning of the twentieth century, very little was known about how earthquakes happen, … See moreMoment magnitude is now the most common measure of earthquake size for medium to large earthquake magnitudes, but in practice, seismic moment (M0 ), the seismological parameter it is based on, is not measured routinely for smaller quakes. For example, the See more
Seismic moment is not a direct measure of energy changes during an earthquake. The relations between seismic moment and the energies involved in an earthquake depend … See more

1931Kiyoo Wadati showed that the maximum amplitude of an earthquake's seismic waves diminished with distance at a certain rate.1935Charles F. Richter worked out how to adjust for epicentral distance (and some other factors) so that the logarithm of the amplitude of the seismograph trace could be used as a measure of "magnitude" that was internally consistent and corresponded roughly with estimates of an earthquake's energy.1979Thomas C. Hanks and Hiroo Kanamori defined a new magnitude scale based on estimates of seismic moment.1995Choy and Boatwright defined the energy magnitude (ME) which is a measure of the energy released by an earthquake.The symbol for the moment magnitude scale is Mw , with the subscript "w" meaning mechanical work accomplished. The moment magnitude Mw is a dimensionless value defined … See more
Assuming the values of σ̄/μ are the same for all earthquakes, one can consider Mw as a measure of the potential energy change ΔW caused by earthquakes. Similarly, if one … See more
