I intended to put this post into another thread dealing with changes observed by Inuit hunters in the location of sunrise and sunset in their
locality. (The far north.
However, since this post brings up questions of mechanics and motion and gyroscopes, I thought it best to move it to a forum frequented by hard nosed
The post also deals with Planet X the famous (some would say mythical) interloper, reputed to have caused havoc in the solar system in the past and
said to be on a return trip into our neighborhood.
I realize that Phillip Plait and others have thoroughly debunked Planet X and that in their view no serious person would even bring it up in a
discussion, because that subject is just sooo
done with and over. So I am not mentioning Planet X, not even once. The words Planet X will not
be tapped onto the keyboard by me.
On second thought, to avoid using the phrase "the p word", I will mention Planet X.
Moving on to the subject of rotational mechanics, I am hoping to tap the wisdom and learning of science and engineering types in the forum.
Here is the post I was going to put into the other thread.

In a post earlier in the thread I referred to the large earthquake that occurred in Japan recently, the so-called Tohoku
earthquake. It is said
to have shifted the earth on its axis by a very small fraction of a percent.

The earthquake moved Honshu 2.4 m (8 ft) east and shifted the Earth on its axis by estimates of between 10 cm (4 in) and 25 cm (10
This information disturbs me a little. The reason is that, I can't think of a mechanism by which an earthquake, even an 8.9 on the Richter Scale,
could shift the rotational axis of a gyroscope the size of the earth.
This begs the question, "Did the earthquake cause a shift of the rotational axis of the earth or did a shift in the rotational axis of the earth
cause the earthquake?"
If the latter, a much more likely scenario in my humble opinion, is true, then that begs another question.
What caused the rotational axis of the earth to shift?
Keep in mind that the earth bulges out around the equator and also keep in mind that Planet X is thought to be in an orbit which is at a sharp angle
to the plane of the ecliptic and also is thought to be approaching from the south of the ecliptic.
Would the approach of such a body, in that position not possibly tug gravitationally at the equatorial bulge in our planet and tend to pull that huge
gyroscope off its rotational axis?
Is Tohoku the first important sign of the approach of Planet X? People like Ann Eller and others believe that it is. A lot of these people are nice
but not very convincing, science wise.
However, coming from the science community, an explanation like the statement, "The earthquake caused the earth's axis to shift.", is also, not very
convincing. To me it makes no sense mechanically.
You could think of the earth as a giant rotating liquid
gyroscope. If its rotational axis were to shift by any amount, but for the sake of
discussion let's say a minute
amount, might this not cause a pertubation of the rotating liquid, resulting in a very, very small ripple or
on its surface?
If the rotating liquid gyroscope were covered with a very thin crust of solid material, might not this very small ripple or wave cause the crust to
crack under stress at some point? Some point like offshore of Fukushima, where a fault in the surface crust might be at just the right spot and in
just the right configuration to encounter the ripple or wave and fracture under the stress?
Hard science people have been saying that we should see pertubations in planetary orbits, etc., if any large body were to enter the solar system.
Well, are we now seeing evidence of an interloper, or was the axis shift really
caused by an earthquake?
