Dear Roland,

I visited recently and decided to reply to your email
regarding "hot spots".  I say that crustal slippage and hot spots are
compatible with each other.  Let a hot spot be represented by a hole in the
surface of a hollow sphere (magma represents the hollow part).  If one
rotates the hollow sphere (say 30 degrees), the hole in the surface will
still be in the same place relative to surface features.  The hole would
however be over a new magma location.  The old magma location would be under
a very solid tectonic plate.  In essence, after a crustal shift, new magma
would continue to rise thru the hot spot.  No conflict in theories.
Crustal slippage and continental drift are also compatible.  As the tectonic
plate slowly moves over a hot spot thru geological time, we get the Hawaiian
Islands.  The surface features do change slowly relative to each other via
continental drift.  A crustal slippage is a sudden event in my opinion (on
the order of days or weeks).  No conflict in theories.
I believe the evidence discovered to date supports a crustal shift
(geological, agricultural, historical, mathematical, etc).  It is the
mechanism that is in question.  A build of ice at the poles, unbalancing the
earth.  An asteroid impact knocking the earth off kilter.  These are the
best possible causes of a crustal shift to date.  As far as mechanism, stay
tuned.  New things are learned every day.

I don't believe that rapid crustal slippage has happened(at least not in the
last several million years). Volcanic islands are built up when a particular
area of the crust sits over a hot-spot in the mantle for an extended period
of time. The long chain of the present and past Hawiian Islands were created
as the Pacific Plate slid slowly over such a hot-spot under the Pacific
Ocean. If the crust slid around as some are contending these islands would
be scattered all over the Pacific Basin, or more likely, would not exist at
all. These islands were simply the first case to occur to me, and because of
them being strung out in a NW SE line are obvious counter evidence. You can
post this where ever you think appropriate.
