The earthquake that struck northeastern Japan on Friday was initally measured to be an 8.8-magnitude. The U.S. Geological Survey deemed it to be an 8.9-magnitude, and now on Sunday, the Japan Meteorological Agency has upgraded it to a solid 9.0.

The upgrade now moves the quake up from the fifth-most powerful earthquake ever recorded to a tie for fourth. The 1952 Kamchatka quake is tied for fourth. First, second and third on the list include Chile's 9.5 quake in 1960, Alaska's 9.2 in 1964, and Sumatra's 9.1 in 2004.

More than 2,000 people are believed to have died so far and many thousands more are still missing or unaccounted for.

1. I saw 9.1

Since it is a Log N scale, each .x would basically double the energy

2. I wouldn't doubt that. I just saw this on twitter...

Japan Meteorological Agency- the possibility that aftershock over M7.0 occurs within 3 days is 70% http://nhk.jp/N3ug68tt (This link is in Japanese but the tweet was in English)
