Yes, well.....it's these Mahler symphonies that cause earthquakes. We all know that. ;)

Apparently the asteroid belt was once a concrete ring around the inner planets because the noise was disturbing the good folk on Jupiter and environs but Mahler's 8th shattered it.

I've noticed that while driving to and from work recently.

I see. All those buildings are really still standing up straight--it's the Earth that's gone crooked.

They don't indicate the normal amount of variability in the day length compare to how much we got from the Chilean earthquake. Come on reporters, do your homework.

For example, wouldn't the gravitational effects of the moon and the swishing around of the oceans (the tides) affect the length of rotation?

I was wondering. If at midnight I'm in the lobby of a hotel, but the next day at midnight I'm asleep on the 30th story wouldn't my day have been a little longer because I've travelled farther through space. Probably lots of microseconds involved there, and I haven't even changed time zones.

It seems to be a little more crooked in relation to some buildings than to others.

I had heard about it right after the quake, and was surprised the story didn't get more play, because something like this could be truly big.

I didn't know it was only about a millionth of a second a day. :)
I'm glad.

I'm still not sure this won't have effects beyond just the minuscule time difference.

P.S. If I were them (and I'm glad I'm not) :) I'd look into whether the different shifts that occur for different quakes (assuming there are other such occurrences) tend to balance one another out or to be in the same direction.

I'm assuming it had been essentially zero.......or if not, that this is an amount of decrease in the average length of the day from what it had been, which would still be significant. But more likely the former.

I don't know if it's important, but I'd bet it's right.

What with Continental Rifting and Plate Tectonics,
our Earth is never asleep. The tiny shift on its axis
is not all that significant for mother Earth.

Well, lets just say that no cataclysmic pole shifts occured
or we would have known it from calamities such as floods and
tectonic events.

That requires knowing about what I wondered about earlier: whether there have been similar shifts in the past, and whether they have tended to 'cancel one another out' or whether they've tended to be in the same direction.

If you know any of that, please sing out.
If you don't, I don't think you have a basis for what you said.

Mark, as you know, I did not write the article I posted. If you are
interested in polar shifts, I am sure there is plenty of information
on the internet. I am not an expert on Earth's axis shifts but from memory
the last such catastrophe occured 800 million years ago.

December, 2009

Earth's north magnetic pole is racing toward Russia at almost 40 miles (64 kilometers) a year due to magnetic changes in the planet's core, new research says.

The core is too deep for scientists to directly detect its magnetic field. But researchers can infer the field's movements by tracking how Earth's magnetic field has been changing at the surface and in space.

Now, newly analyzed data suggest that there's a region of rapidly changing magnetism on the core's surface, possibly being created by a mysterious "plume" of magnetism arising from deeper in the core.

And it's this region that could be pulling the magnetic pole away from its long-time location in northern Canada, said Arnaud Chulliat, a geophysicist at the Institut de Physique du Globe de Paris in France.

And it's this region that could be pulling the magnetic pole away from its long-time location in northern Canada, said Arnaud Chulliat, a geophysicist at the Institut de Physique du Globe de Paris in France.

Finding North

Magnetic north, which is the place where compass needles actually point, is near but not exactly in the same place as the geographic North Pole. Right now, magnetic north is close to Canada's Ellesmere Island.

Navigators have used magnetic north for centuries to orient themselves when they're far from recognizable landmarks.

Although global positioning systems have largely replaced such traditional techniques, many people still find compasses useful for getting around underwater and underground where GPS satellites can't communicate.

The magnetic north pole had moved little from the time scientists first located it in 1831. Then in 1904, the pole began shifting northeastward at a steady pace of about 9 miles (15 kilometers) a year.

In 1989 it sped up again, and in 2007 scientists confirmed that the pole is now galloping toward Siberia at 34 to 37 miles (55 to 60 kilometers) a year.

A rapidly shifting magnetic pole means that magnetic-field maps need to be updated more often to allow compass users to make the crucial adjustment from magnetic north to true North.

Wandering Pole

Geologists think Earth has a magnetic field because the core is made up of a solid iron center surrounded by rapidly spinning liquid metal. This creates a "dynamo" that drives our magnetic field.

Scientists had long suspected that, since the molten core is constantly moving, changes in its magnetism might be affecting the surface location of magnetic north.

Although the new research seems to back up this idea, Chulliat is not ready to say whether magnetic north will eventually cross into Russia.

"It's too difficult to forecast," Chulliat said.

Also, nobody knows when another change in the core might pop up elsewhere, sending magnetic north wandering in a new direction.

Chulliat presented his work this week at a meeting of the American Geophysical Union in San Francisco.

I have always wanted to go to Lapland. For all Lapland lovers like me may I suggest you the wonderful Symphony No.3 by the swedish composer Wilhelm Petersen-Berger ? Excellent piece if you ask me.
