The largest-ever earthquake with a magnitude of 9.6 occurred in China in 1916.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. The moment-magnitude scale is logarithmic, so an increase of one unit means an earthquake is 10 times bigger, with about 30 times the energy produced. Small earthquakes have about the same value on the Richter scale and the moment magnitude scale, so Richter is fine for those. As defined, an earthquake magnitude scale has no lower or upper limit. Sensitive seismographs can record earthquakes with magnitudes of negative value and have recorded magnitudes up to about 9.0. (The 1906 San Francisco earthquake, for example, had a Richter magnitude of 8.25.) The moment magnitude scale is another earthquake measurement scale used by some seismologists.
