And when I speak of "pole-shift", I'm not saying the Earth suddenly flips over, the angular momentum is far to great. I'm speaking of some type of rapid, large crustal displacement, the astronomical pole would stay the same, but worldwide, except for antipodal nodes, the latitudes would change.

I'm speaking of some type of rapid, large crustal displacement, the astronomical pole would stay the same, but worldwide, except for antipodal nodes, the latitudes would change.

From what I have read, the evidence from the mid Atlantic ridge does not support this. However, it does support the fact that the MAGNETIC poles reverse. Also there may be tens of millions of years between each of these events. (Note; should not effect the plate tectonic drift rates)

However, I am NOT a geophysicist so I will leave this up to far more qualified folks than I to correct me if I am wrong here.
