The Japanese Meteorological Agency has re-evaluated the March 11 earthquake and increased the magnitude from 8.8 to 9.0.

However on the U.S. Geological Survey web site, the March 11 earthquake remains an 8.9 magnitude quake.

The Japanese agency said it upgraded the magnitude because of its analysis of the earthquake. A spokesman said very different and unusual wave types were found and that it was very rare type of earthquake.

The Japanese meteorological agency estimated Sunday that there will be a 70 percent chance to get M7 or over aftershocks within 3 days.

Here is a list of the top known earthquakes by their magnitudes from the Japanese agency.

1. Chile earthquake, 1960, Magnitude 9.5
2. Sumatra earthquake, 2004, Magnitude 9.1~9.3
3. Alaska earthquake, 1964 , Magnitude M9.2
4. Alika earthquake, 1868, Magnitude M9.1
5. Kamuchakka earthquake, 1952, Magnitude 9
6. Japan Earthquake, March 11, 2011 Magnitude 9
