Tilting Axis???????
 

Just caught a news headline earlire today on Classic FM that the
earthquake had caused a wobble on the earth's axis?
Anyone else hear this and is this a possibility or is it the usual
Classic FM news headline iffy reprting?
Their weather forecasting is appalling.

Sounds like a lot of idiotic nonsense to me.
I thought the 'silly season' was in August.

I can't see how the release of energy (colossal though it was) could
possibly have been anywhere near enough, by many orders of
magnitude, to affect the tilt of the earth's axis.

Of course *theoretically* it could have a very *very* small effect.
But only in the same way that the law of conservation of momentum
says that if I jump up, when I land the whole earth moves just a little
tiny bit.......

Indeed:
http://english.aljazeera.net/NR/exer...4989472FBE.htm

"It now spins 3 microseconds (millionth of a second) faster and has
tilt about two and a half centimetres on its axis."

And: "The Earth's poles travel in a circular path that normally varies
by about 10 metres, so an added wobble of 0.025m is unlikely to cause
long-term effects, the scientist said."

Phew! :)

The USGS website provides more reliable information on the earthquake
http://earthquake.usgs.gov/eqinthenews/2004/usslav/

Media report USGS experts confirming/denying any effect on earth's axis.
Depends on which news report you look at(!). Can't find any mention on the
USGS site.

All the best

Half heard mention in the ITV1 news just now, there doesn't appear to
be a (relevant) search engine on the ITV News website.

Does it even do that I wonder?
That may be the amount it would move theoretically if the earth was
a perfectly elastic solid body. However it's not and the vast majority
of the earth is made up of viscous molten rock which would simply
absorb the energy rather than transmit it.

Not so much the energy release but the shift of mass. A quick dig
about on the web after the OPs post indicated that quite large
movements have taken place, tens of meters possibly 100 metres, over
huge areas. That is a lot of mass and could well make the earths
rotation shudder. I doubt that there is any measurable lasting effect.

I guess over the next few weeks and some close observation how much
shorter 26th Dec 2004 actually was will come to light.

But only in the same way that the law of conservation of momentum
says that if I jump up, when I land the whole earth moves just a
little tiny bit.......

The same amount it moved when you jumped up, but we are talking some
what larger masses in the case of the recent earthquake...
