Seismologists at the US Geological Survey in Menlo Park, California, have just revised their calculations regarding the magnitude of today's quake. They now say it was magnitude 9.0. Already one of the top 10 recorded earthquakes in history, the revision suggests the quake was even more powerful than first thought.

Harold Tobin of the University of Wisconsin-Madison told New Scientist that this figure will probably change again. This is typical in the hours after a large seismic event, as more information becomes available.
