The Japan earthquake of March 11, 2011 was a 9.0 on the moment magnitude scale, which replaced the Richter scale.
1X = 9
The 2011 earthquake in Tohoku, Japan measured at a Mercalli intensity of VII (Very strong). The Earthquake had a magnitude of 9.0 and led to widespread damage and casualties.
8.9 on the Richter scale.
The rating was 9.0, which is almost complete destruction.

The Modified Mercalli Intensity (MMI) level of the Japan earthquake on March 11, 2011, was around VII to IX, varying across different locations. The earthquake caused widespread damage and triggered a devastating tsunami that led to significant destruction and loss of life.
The 2011 Tohoku earthquake measured 9.0 on the Richter scale.
At first they estimated it as an 8.9 on the Richter scale, but later was revised as a 9.0.
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of the 2011 Japan earthquake on moment magnitude scale is 9.0.The use of the Richter magnitude scale has largely been replaced by the moment magnitude scale in most countries.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.
