What was the Japan Earthquake 2011 on the moment magnitude scale?
Wiki User
∙ 11y ago
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The use of the Richter magnitude scale has largely been replaced by the moment magnitude scale in most countries.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 does the moment magnitude scale measure?
the moment magnitude scale rates an earthquake by estimating the total energy released during an earthquake
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 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 is the 10-point scale used to record the magnitude of earthquake?
There are two The Richter Scale and the Moment 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 was the magnitude of the earthquake in Christchruch?
7.0 on the Moment Magnitude Scale.
What does the moment magnitude scale measure?

What are the advantages the moment magnitude scale to measure an earthquake?
to rate an earthquake
What is an earthquake's magnitude a measure of?
An earthquake's magnitude is a measure of how strong it is
What are the advantages of using the moment magnitude scale to measure of earthquake?
to rate an earthquake
What scale is most often used to measure the scale of an earthquake?
The Moment Magnitude scale.

What is the most accurate measurement of an earthquake's magnitude?
The Seismic Moment Scale is the most accurate measurement of an earthquake's magnitude.
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 Formerly the Richter magnitude scale was used, but this has now been replaced by the Moment magnitude scale.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 scales are used to measure the magnitude of earthquakes?
The instrument that is used to measure the magnitude of an earthquake is a seismometer.
