Quake rattled Earth orbit, changed map of Asia:  US geophysicist
An earthquake that unleashed deadly tidal waves 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.
