Japanese Earthquake Upgraded to 9.0
The US Geological Survey has upgraded the magnitude of Friday's deadly earthquake in Japan to 9.0. The move comes after Japan's Meteorological Agency did the same.
US government scientists originally put the Japan 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.
The deadly earthquake that struck Japan last week has been upgraded from an 8.9 to a 9.0-magnitude, the U.S. Geological Survey (USGS) announced today (March 14).
This magnitude places the earthquake as the fourth largest in the world since 1900 and the largest in Japan since modern instrumental recordings began 130 years ago, according to the USGS.
