8.9 on the Richter scale.
The rating was 9.0, which is almost complete destruction.
The Japan earthquake of March 11, 2011 was a 9.0 on the moment magnitude scale, which replaced the Richter scale.
actually, the highest rating was an earthquake in Chili, coming in on a 9.5
The rating system used to estimate the total energy released by an earthquake is the Moment Magnitude Scale.
There were over 16,000 deaths in Japan's major 2011 earthquake.
