Scientists say that the eartquake that triggered last weekend's deadly tsunamis also may have altered the global map.

They say that the eartquake caused a little blip in the earth's rotation. Though it isn't anything that will cause noticeable effects.
``I'd anticipate some permanent change'' James Devine, senior science adviser to the director of the U.S. Geological Survey, said in an interview.

``The atomic clocks will still work,'' he said.

William Wooden, head of the Earth Orientation Department of the U.S. Naval Observatory, agrees.

``There's no significant change,'' he said. ``It's tiny and within the range of the kind of change we see on a daily basis.''

The land shift, though, likely means that scientists will have to change the location of some global positioning systems, according to Wooden.

``That's not routine work,'' he said.
