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).”

Luckily, this is not the first time it happens, every earth quake has an influence on our planet. However, we might be able to see some other visible changes like islands moving positions (Lost
) !
Yeah man, we heard this on the radio this morning. Assume 3 inches in the overall scheme of things isn't a lot but still ....
The truth speaks for itself about the end is near...my condolences to those who are suffering and losing their love ones. God give you strength, amen.
