Strength of deadly Japan quake increased to 9.0

The U.S. Geological Survey has upgraded the magnitude of Friday's deadly earthquake in Japan to 9.0

The move Monday comes after Japan's Meteorological Agency did the same. It's not unusual for scientists to tweak the magnitude of a giant after some number-crunching.

U.S. government scientists originally put the quake at 8.9. The change to 9.0 means that the quake was about 1.5 times stronger than initially thought.

The Japan quake is now the fourth largest in the world since 1900 behind the 2004 magnitude-9.1 Sumatra quake.

Tombstone read "Died in 8.9 magnitude (estimated) earthwake, latter revised to 9.0 (another estimate). All estimates are pee-reviewed".
Wonderful. And utterly useless to the dead. No seimoslogist has accurately predicted the time, place and strength of an impedding earthquake anywhere. However, their handwaving is pee-revewed, so they can lord over the astrologers and nutcases.
