There ARE arguments for and against Crustal shift, it does happen but slowly over time, the potential for a rapid shift however does exist but there is little or no evidence to support it.

There are argument's against that do hold water and can not be argued away easily though which for me put this theory out of the image.

Geothermal plume theory is as you know all about vulcanism and the idea that plumes of superheated magma rise from very deep in the earth up to the crust and cause the formation of Volcanic region's, these hexagonal column's of superheated magma stay in more or less the same place just like the red spot on jupitor does.

Now if there had been a Crustal shift as Charles Hapgood theorised then we should find evidence of this in the movement of volcanos which have formed over these Geothermal plume's, especially ancient ones.

There are at LEAST two sites that show absolutly no crustal shift of the magnitude a total crustal shift would have caused, there location relative to one another also show's that they were not at the pole of such a shift so that can not be argued either.

These two important geothermal plume sites are of course the Yellowstone national park which has great age and can be traced back geologically many millions of years and the other is the Hawaiian island's which have a trail of earlier islands now sunken down and forming sea mount's with the oldest former Hawaiian island's now little more than bumps on the sea bed, this chain starting with the current islands and progressing back over the more ancient sea mount's shows where the crust has moved SLOWLY over the geothermal plume over time.

Mechanically however it could happen but would require something very massive to cause it and would likely cause massive crustal upset around the entire globe but other than the formation of new geothermal plumes which of course does happen over time it is a rare occurance and possibly one of the mechanism's that helped to bring about the break up of the supercontinent's though it is far more likely this was simply a new geothermal plume or chain of them like we still have in the ring of fire today.

The amount of force needed to enact a global crustal shift is perhaps far beyond the mechanical centrifugal force that they asymetric build up of ice Hapgood theorised would be able to apply especially since the Magma displacement below the crust actually compensates for the Asymetric build up of the ice on top of the crust anyway (if more slowly).

Of course geothermal plumes may cease or change position much like any other convection current and the Deccan traps are a good example of one that has either extinguished or moved elsewhere but that is over 65 million years so not as fast as that theory would suggest.

It is worth noting I also believed that theory for long time until I heard of geothermal plume theory.

Thank you all for your posts! I have some great reading and watcging to do.
