Japan earthquake may have shortened length of days and shifted Earth?s axis

Using a complex model to perform a theoretical calculation based on a U.S. Geological Survey, Richard Gross of NASA's Jet Propulsion Laboratory (JPL) has determined that by changing the distribution of the Earth's mass, the earthquake that devastated Japan last Friday should have sped up the Earth's rotation, resulting in a day that is about 1.8 microseconds (1.8 millionths of a second) shorter...
