I heard this at the end of a news break on the radio once. Has anyone else heard anything about this? It sounds important if it's possible. What if the earth's axis or orbit around the sun was changed. I'm looking for links with info on this.
Quake May Have Altered Earth's Rotation // May have shortened the day by 3 microseconds, said gravity expert Richard Gross of Jet Propulsion Laboratory, Pasadena...
On premise a slab slid into core, Gross said he's done calculations 'to see what effect this (earthquake) should have had.' The result: A day shortened... 'We won't know for weeks,' said a geophysicist at Massachusetts Institute of Technology. 'So it's a guess, as of now'...
The black helicopters will arrive overhead 3 microseconds later. Relax.
If the day is shorter by 3 microseconds, that would translate into a milisecond per year. That may not sound like much, but for some applications it could become significant. For example, unless GPS satelites are recalibrated (which I would expect should happen), the change in rotation would cause logitude readings to vary by half a meter per year at the equator.
Yep, for navigational purposes, especially in the open waters, 3 microseconds is a big deal.
I'm wondering about this, too.
Strategerist, what do you say about this?

Aw jeez, now I'm going to be lumped in with the duplicate post squad.

Quake rattled Earth orbit, changed map of Asia: US geophysicist
on Asia was so powerful it made the Earth wobble on its axis and permanently altered the regional map, US geophysicists said.
The 9.0-magnitude temblor that struck 250 kilometers (155 miles) southeast of Sumatra island Sunday may have moved small islands as much as 20 meters (66 feet), according to one expert.
"That earthquake has changed the map," US Geological Survey expert Ken Hudnut told AFP.
"Based on seismic modeling, some of the smaller islands off the southwest coast of Sumatra may have moved to the southwest by about 20 meters. That is a lot of slip."
The northwestern tip of the Indonesian territory of Sumatra may also have shifted to the southwest by around 36 meters (120 feet), Hudnut said.
In addition, the energy released as the two sides of the undersea fault slipped against each other made the Earth wobble on its axis, Hudnut said.
"We can detect very slight motions of the Earth and I would expect that the Earth wobbled in its orbit when the earthquake occurred due the massive amount of energy exerted and the sudden shift in mass," Hudnut said.
Another USGS research geophysicist agreed that the Earth would have got a "little jog," and that the islands off Sumatra would have been moved by the quake.
However, Stuart Sipkin, of the USGS National Earthquake Information Center in Golden Colorado, said it was more likely that the islands off Sumatra had risen higher out of the sea than they had moved laterally.
"In in this case, the Indian plate dived below the Burma plate, causing uplift, so most of the motion to the islands would have been vertical, not horizontal."
The tsunamis unleashed by the fourth-biggest earthquake in a century have left at least 23,675 people dead in eight countries across Asia and as far as Somalia in East Africa.
The tsunamis wiped out entire coastal villages and pulled beach-goers out to sea.
The International Red Cross estimated that up to one million people have been displaced by the natural calamity.

Theoretically true of any earthquake.
If it weren't for super-accurate atomic clocks, we'd never know. It's still mighty impressive.
Proofreading of title is a good thing...
Yes it looks like it is minor but I am going to keep my eye on it. There was a time(about 7years ago) when I was into prophecy. I fell for most of the doomsday senarios about the year 2000 until I was closer to it. I am happy to be wrong about all of that nonsense but something big was suppose to happen in 04 and I was concerned about the earthquake. Just a few days left, I think we will be O.K..

Good for you! I'm glad you're ok - the 63000 death toll almost had me depressed, but hearing that you're OK makes everything much much better.
Yep. Possibly 100,000 dead - looks minor. Nut.

Posited effect is a 3 microsecond shorter day. No effect on Earth's orbit. The rotation rate of the Earth slows down about 2 milliseconds (2000 microseconds) per day per century due to "tidal friction". This Earthquake might offset less than two months of normal slow-down. Relax.
Go here, they mention the "possible" effects of earthquakes. http://maia.usno.navy.mil/eop.html
