I heard that the tsunami in Asia in 2005 caused the Earth to wobble. Can this be true?

Answer 1

You mean December 2004. Yes, it did. But not that much. It was the earthquake that did it, actually, and it was a quickening of the spin, not so much a wobble.

"The ''megathrust" earthquake that struck Dec. 26 may cause New Year's Day 3005 to start as much as a second earlier. The first computer models of the devastating Asian quake found that it caused the Earth to spin faster, shortening each day by nearly 3millionths of a second and shifting the planet's axis about an inch.
