Estimated wave height: 10 meters. Earthquake Richter scale: 8.9
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of the 2011 Japan earthquake on moment magnitude scale is 9.0.The use of the Richter magnitude scale has largely been replaced by the moment magnitude scale in most countries.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.
