The incidence of conicity in the volcanic activity

From different aspects we intend to demonstrate the incidence of the form in the different parameters of the Volcano's state, which is assumed as an exponential cone. The thermostatic, thermodynamic, chemical and optical aspects of the volcano assumed in the latter case as an ideal black body are reviewed. We conclude that the volcano is a physical-chemical device that "prepares" for an eruption, which is imminent.
