A megaincendio is a fire of immense proportions a conflagration of colossal magnitude and that is almost impossible to extinguish. The term became popular after 687 simultaneous conflagrations that occurred in Chile, where a catastrophic forest fire burned nearly 600,000 hectares of forest, destroying everything in its path. They were such dimensions that it was necessary to open a new category in magnitudes of fire ( the sixth category ). According to the studies of Chilean agencies, burned an average of 8,200 hectares per hour and the calorific power of the flames overcame the 60,000 kilowatts per metre and is presumed to affect the atmosphere at the continental level.
