The Earth's Shifting Crust by Charles Hapgood - wire of information

i8o EARTH'S SHIFTING CRUST
c. Despite the fact that such loads may
wholly or in part,
cancel each other
in so far as the transmission of a net
centrifugal momentum to the crust in any given direction
is concerned, nevertheless their opposition will involve
the creation of persisting stresses in the crust, and
these may be a cause of seismic activity.
d. Crustal distortions, unlike icecaps, are comparatively
permanent features; many may persist through one or
more displacements; their effect will change quantita-
tively according to their changes of latitude and longitude.
e. At the termination of each crustal movement, the dis-
tortions of the rock structures of the crust should be
approximately balanced across the equator. In a period
of several thousand years following such a movement,
however, the process of isostatic adjustment, proceeding
faster in some areas than in others, may disturb this
balance and predispose the crust to a new displacement.
f. We may conclude, in answer to the question raised in
the Foreword, that while some of these distortions are
massive, they tend to be balanced across the equator,
and that the principal disturbing factor, from the
quantitative standpoint, must in all probability
rapidly growing continental icecap.
4. The Triaxial Shape of the Earth
be the
We cannot leave the subject of the gravitational adjustment
of the earth's surface without mentioning the greatest dis-
tortion of all, the triaxial deformation of the earth. It is all
the more important to consider this question since here we
shall see, at one and the same time, a solution for one of the
greatest of geological conundrums, and one of the most
powerful arguments in support of the theory of displacements
of the earth's crust.
Not long ago, scientists became aware of the fact that there
