  • noun
  • /ˈmoʊmənt ˈmæɡnɪtud skeɪl/
  • Specialized
translation icon : escala de magnitud de momento
  • After the quake, officials reported its strength as 7.2 on the moment magnitude scale.

Examples

  • Seismologists use the moment magnitude scale to assess the energy released by recent seismic events.

  • The moment magnitude scale provides a more accurate measurement of large earthquakes than the Richter scale.

  • The moment magnitude scale is crucial.

  • How does the moment magnitude scale work?

  • The moment magnitude scale provides a more accurate measure of an earthquake's size than the Richter scale.

  • Seismologists rely on the moment magnitude scale to assess the energy released during major earthquakes.

  • Using the moment magnitude scale, researchers reported that the earthquake was significantly stronger than initially thought.

Morphology

moment + magnitude + scale

The phrase is compositionally built from 'moment' + 'magnitude' + 'scale', so a learner who knows those words can infer it is a scale measuring the size or magnitude of a 'moment' (i.e., something about size/energy). However, in seismology 'moment' has a technical meaning ('seismic moment') and the precise logarithmic energy measure is specialized, so the full meaning is not predictable to a B1 learner without domain knowledge.

Etymology

Moment magnitude scale uses moment to mean the actual break of the ground and magnitude to mean the size of that break. It measures how big the break and the forces were to give a single number for the quake's 'energy', so the name helps you remember it shows the earthquake's power.
