               The secrets of the Circle of Fire lies somewhere
   deep into the Earths formation about 4.5 - 5 billion years ago.

          The Circle of Fire is a ring of volcanic mountains that
  Borders the coasts of North and South America, along with Asia
  and Thialand. It also forms a semi-cirlce from the southern tip 
  of South America to Australia.
 
         The Earth is about 4.5 - 5 billion Years old. Whereas 
  man's recorded history is only about 5000 years old.(Circle of fire
  page 3) The Earth is made up of 3 different layers 1- The Crust, the
  Crust is the very top layer of the earth that we live on, it consits
  of 7 different crustal plates. 2- The mantle which is the middle 
  layer, This is made of a liquid plastic type of material called 
  magma, This material is constantly flowing which causes the crustal
  plates to shift.3- The Inner Core, this is the very center of the 
  Earth, Scientists aren't positive but they believe that it is solid 
  lava.
 
        About 80% of the worlds Earthquakes occur in the Circle of 
  Fire. (The Circle of Fire p. 13) They happen in a narrow belt of 
  faults that run parallel with the equator from North and South
  America to Asia.
 
        In 1950 an Expidition from Scripps Institute of Oceanography
  while exploring the sea floor off the coast of California discoverd
  fracture Zones.(Circle of Fire p 17) These fracture zones run
  parallel with the equator from North and South America to Asia down
  to Thailand as well. Often these fracture zones are not deep but 
  they run ten to twenty miles wide. And amazingly the run in an 
  almost equal distance of about 400 - 500 miles long.

       The Circle of Fire is a mysterious place. Though no one 
  knows how it was formed , scientists believe they are close, They
  also believe that once they uncover its secrets, they will be able 
  to answer many of the unsolved questions of the Earths Formation.
