[QUOTE="Dave70968, post: 2997287, member: 13624"] [URL]http://content.usatoday.com/communities/sciencefair/post/2011/03/japan-earthquake-shifted-earth-axis-shorter-day-nasa/1[/URL] Earth's radius is approximately 251 million inches; a shift of 6.5" is about 1.5 [I]* 10^-6[/I] degrees. Don't worry, you were only off by a factor of one million. And it's not a shift of the average axial position, just a change in the wobble; nothing on earth could cause a net change (as the above article notes). Close enough for government work, as they say. Incidentally, there's this nifty research tool at your fingertips that makes the Great Library at Alexandria look like a comic-book shop. It's called "Google;" perhaps you've heard of it. [/QUOTE]
