The temperature and rate of discharge of hot springs depend on factors such as the rate at which water circulates through the system of underground channelways, the amount of heat supplied at depth, and the extent of dilution of the heated water by cool ground water near the surface. A deposit of hot ash and shattered rock laid down by an explosive volcanic eruption may cover many square miles of ground and be hundreds of feet deep.

Sometimes colonies of bacteria and blue-green algae flourish in pools of scalding hot spring water on the surface. The pressure and heat contained in its interior, along with the gases dissolved in the magma, caused the escaping of these volcanic materials through the cracks and voids of the mountain, blasting out a large portion of the mount and creating a 1.
