The belt of earthquake and volcanic
activity that runs around the edge of the Pacific Ocean is called
the 'Ring of Fire'. The compressional fault lines and subduction
zones in this region create the fold mountain ranges along the west
coasts of North and South America and many of the volcanic island
chains and earthquake activity of the South East Asian seas. In
this model the overall expansion of the Pacific seabeds ( pushing
outwards opposite the point of original impact and entry, the Indian
plate ). The new seabeds slip back under the continents, back into
the mantle, while simultaneously pushing the continental plates
apart.
Comparing this to the pattern of volcanic activity after the original
impact shows that the Pacific effectively closes and all land masses
around the Ring of Fire meet. North and South America rejoin along
their west coasts, Australia, Antractica and Africa are pulled in
to fill the main sweep of the Pacific. Africa rejoins the East coast
of South America and the East coast of Australia meets Canada and
Alaska. It is important to re-iterate that this re-alignment ( although
this section does ot touch on the interior ) is consistent with
the positioning of fault types ( if an allowance is made for a re-interpretation
of certain compressional areas, as outlined abve ) and also consistent
with the magnetic striping of the continental plates and the original
shields ( see
enlarged diagram ).
Note: It is this particular movement of the folding back onto
itself of North and South America and the central American faults
acting as a hinge which differs from the Expanding Earth models
aswell as from conventional Plate-Tectonics ( see: 'Origins:
Pangea X' ). Expanding Earth ( 'eess'
) also does not go back as far as reconstructing the earliest
Pe-Cambrian Shields.
