March 1 (Bloomberg) -- The earthquake that killed more than 700 people in Chile on Feb. 27 probably shifted the Earth’s axis and shortened the day, a National Aeronautics and Space Administration scientist said.
Earthquakes can involve shifting hundreds of kilometers of rock by several meters, changing the distribution of mass on the planet. This affects the Earth’s rotation, said Richard Gross, a geophysicist at NASA’s Jet Propulsion Laboratory in Pasadena, California, who uses a computer model to calculate the effects.
“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).”
If by a "Liberal" they mean someone who looks ahead and not behind, someone who welcomes new ideas without rigid reactions, someone who cares about the welfare of the people - their health, their housing, their schools, their jobs, their civil rights, and their civil liberties - someone who believes we can break through the stalemate and suspicions that grip us in our policies abroad; if that is what they mean by a "Liberal," then I'm proud to say I'm a "Liberal." - John F.

If Climate Change Isn't Enough
Seems the earthquake in Chile, besides being a disaster for Chileans, has directly affected the rest of us as well.
