The Day the Earth Sped Up

Saturday, April 16, 2011

The quake in Japan shaved about one-millionth of second off our day and tilted the planet's axis by several inches.

* The massive earthquake that hit Japan sped up Earth's spin by a microsecond and tilted the axis by several inches.
* The shift happened when massive amounts of the planet's crust tumbled inside a 250-mile long crack that opened up six miles beneath the Pacific Ocean.
* Changes in Earth's tilt are associated with ice ages.
