Abstract:  The Paper begins with a brief account of the Pacific Ring of Fire and the location of Volcanoes  in the Earth. The Magma Chamber and introduction to convection of Magma in the chamber are given vividly in a self-styled manner. The Rayleigh number is arrived at by making use of an extensive theory based on Navier-Stoke’s equation of Fluid Mechanics. Graphical study of various critical Rayleigh numbers  for the corresponding wave numbers. The instability of convection and the magma turbulence in the chamber leading to  magma fragmentation and ultimately eruption.  The Rayleigh number  for magma in the chamber has been worked out. The Paper ends with a Conclusion.
