Chilean Quake Likely Shifted Earth’s Axis, NASA Scientist Says

The length of the day should have gotten shorter by 1.26 microseconds (millionths of a second),” Gross, said today in an e-mailed reply to questions. “The axis about which the Earth’s mass is balanced should have moved by 2.7 milliarcseconds (about 8 centimeters or 3 inches).”

I can't imagine spending my days coming up with such data. Maybe that's just me, though.
