The moment magnitude scale (MMS; denoted explicitly with M or M w 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. M w was defined in a 1979 paper by Thomas C. Hanks and Hiroo Kanamori.

A escala de magnitude de momento (abreviada como MMS e denotada como , onde w indica trabalho realizado) é usada pelos sismólogos para medir a magnitude dos terremotos em termos de energia liberada. [ 1] A MMS foi introduzida em 1979 por Thomas C. Hanks e Hiroo Kanamori, vindo a substituir a Escala de Richter ( ), desenvolvida nos anos 1930.
Seismic moment is the basis of the moment magnitude scale introduced by Hiroo Kanamori, which is often used to compare the size of different earthquakes and is especially useful for comparing the sizes of large (great) earthquakes. The seismic moment is not restricted to earthquakes.
Learn how the moment magnitude scale measures the size of earthquakes based on their seismic moment and fault geometry. Compare it with other scales and avoid magnitude saturation problems.
