Earthquake - Earthquake magnitude Britannica
For large earthquakes worldwide, the moment magnitude scale (MMS) is most common, although M s is also reported frequently. The seismic moment, M0 , is proportional to the area of the rupture times the average slip that took place in the earthquake, thus it measures the physical size of the event.
