EARTH'S SHIFTING CRUST
pressure on the rock below will be relieved, and the rock
will resume a liquid state. If the arching results in cracking
at the surface, or in sufficient lateral squeezing of the liquid
pockets, eruption may take place. This effect may account for
the vast masses of igneous rock that are found associated with
the folded mountain ranges (215:58), but it is necessary to
ask the question, What causes the arching of the crust? Ob-
viously, volcanism, according to this theory,
must be traced
to the cause of the arching. Hobbs's theory is not very satis-
factory because he cannot explain the arching.
It is clear that volcanism might occur as the result either
of the process imagined by Day or of that imagined by Hobbs,
for several different causes might produce liquid pockets in
the crust. But it is equally clear that neither they nor Daly
has advanced a theory to account for volcanoes, volcanic
zones, plateau basalts, and volcanic mountains. Einstein,
when he first received some material outlining the theory
proposed in this book, wrote me that it was the only theory
he had ever seen that could explain the volcanic zones (128).
These, of course, can be explained as zones of fracture (such
as the rift valleys just mentioned) resulting from crust dis-
placements.
7. The Volcanic Island Arcs
Campbell has suggested an explanation for the formation
of the volcanic island arcs, so many of which are found in
the Pacific, and which consist of chains of volcanic moun-
tains in the sea. He shows not only how our theory of crust
displacement may

As a sector of the lithosphere, or crust, moves toward the equator,
the motion is fastest and the tension is greatest on the meridian of
movement, and great north-south faults will open up, beginning
there and spreading east and west. At the same time transverse faults
