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.

July 22, 2020 You may not always feel the earth shaking, but California has earthquakes occurring all the time. Seismographic networks measure earthquakes by their magnitude, energy release and intensity. Years …Magnitude is the size of the earthquake. An earthquake has a single magnitude. The shaking that it causes has many values that vary from place to place based on distance, type of surface material, and other factors. See the Intensity section below for more details on shaking intensity measurements.v t e Seismic magnitude scales are used to describe the overall strength or "size" of an earthquake. These are distinguished from seismic intensity scales that categorize the intensity or severity of ground shaking (quaking) caused by an earthquake at a given location.
The fault dimensions (length and width) and the amount of slip vary dramatically across the spectrum of earthquake magnitudes. For example, an M w 4 earthquake fault commonly has a length of around 1 km, an M w 7 earthquake has a length of around 40 km, and the 2004 M w 9.1 Sumatra earthquake had a rupture length of over 1000 km.
