The Moment Magnitude Scale (Mw) was developed by the seismologists Hanks and Kanamori during the 70's and their work was published in the Journal of Geophysical Research in 1979.

What scale is used to measure the energy of an earthquake?
A magnitude scale. Formerly the Richter magnitude scale was used, but this has now been replaced by the Moment magnitude scale.
What system do geologists use today for rating the magnitude of an earthquake?
They use the Richter scale to measure magnitude and Moment Measure to measure energy released.
Are Richter Scale Magnitudes or Moment Magnitudes more accurate?
The Moment Magnitude scale is more accurate overall.
What are 3 ways to measure an earthquake?
the Richter scale, Mercalli scale, and Moment Magnitude scale
How are earthquake magnitude and intensity measured?
Earthquake magnitude is measured using a number of differing scales including the Richter scale, the moment magnitude scale and the surface magnitude scale. Intensity is measured using he Modified Mercalli intensity scale.
What scale describes an earthquake with a magnitude?
There are a number of earthquake magnitude scales, including the moment magnitude scale (the scale currently favoured by seismologists), the Richter or local magnitude scale and the surface wave magnitude scale.
What is the moment magnitude scale based on?
The Richter scale
What was the magnitude of the earthquake in Christchruch?
7.0 on the Moment Magnitude Scale.
What was the Japan Earthquake 2011 on the moment magnitude scale?
Magnitude of the 2011 Japan earthquake on moment magnitude scale is 9.0.The use of the Richter magnitude scale has largely been replaced by the moment magnitude scale in most countries. The United States Geological Survey (USGS), for example, uses the moment magnitude scale designated as MMS or Mw to measure all large earthquakes.UPDATE: Official magnitude was updated to 9.1 on Nov 7, 2016.
What are two advantages of the moment magnitude scale over the Richter scale?
The moment magnitude scale is more accurate for large earthquake than can cause damage.
What scale is used to measure the energy of an earthquake?
A magnitude scale. Formerly the Richter magnitude scale was used, but this has now been replaced by the Moment magnitude scale.
What scale is used to measure to energy of an earthquake?
A magnitude scale. Formerly the Richter magnitude scale was used, but this has now been replaced by the Moment magnitude scale.
What are all of the scales for measuring earthquakes?
Moment Magnitude, Ritcher Scale and Mercili Scale.
What does moment magnitude scale measures?
The moment magnitude scale (MW) provides an estimate of the total energy released in an earthquake and is currently the preferred magnitude scale in use by seismologists for measuring large (magnitude greater than 7) earthquakes.
What system do geologists use today for rating the magnitude of an earthquake?
They use the Richter scale to measure magnitude and Moment Measure to measure energy released.
What scale is most often used to measure the scale of an earthquake?
The Moment Magnitude scale.
What does the moment magnitude scale measure?
the moment magnitude scale rates an earthquake by estimating the total energy released during an earthquake
