user posted image rThe deadly Asian earthquake may have permanently accelerated the Earth's rotation -- shortening days by a fraction of a second -- and caused the planet to wobble on its axis, U.S. scientists said on Tuesday. Richard Gross, a geophysicist with NASA's Jet Propulsion Laboratory in California, theorized that a shift of mass toward the Earth's center during the quake on Sunday caused the planet to spin 3 microseconds, or 3 millionths of a second, faster and to tilt about an inch on its axis. When one huge tectonic plate beneath the Indian Ocean was forced below the edge of another "it had the effect of making the Earth more compact and spinning faster," Gross said. Gross said changes predicted by his model probably are too minuscule to be detected by a global positioning satellite network that routinely measures changes in Earth's spin, but said the data may reveal a slight wobble.

The Earth's poles travel a circular path that normally varies by about 33 feet, so an added wobble of an inch is unlikely to cause long-term effects, he said. "That continual motion is just used to changing," Gross said. "The rotation is not actually that precise. The Earth does slow down and change its rate of rotation." When those tiny variations accumulate, planetary scientists must add a "leap second" to the end of a year, something that has not been done in many years, Gross said.

mad.gif And I was hoping for a dramatice climate change. Its 5 degrees f. out side and I would take any warm up as a blessing.

adding a "leap second"? so does that mean after so many years, there's gonna be another day added to February besides the leap year we already have?

Not in our life time I would think. Or at least a good long time.

god dam it i lost 3 millionths of a second on the 26 of dec i could of read a book in that amount of time. omg who cares it was 3 millionths of a second for goodness sake
