The world's smallest volcano El Gato, in Aguas Queñas Cuzco, Peru, is a natural phenomenon caused by underground heat energy, water and heat that erupts at temperatures of about 80-90 degrees Celsius, caused by the accumulation of underground heat released through small openings in the Earth's crust, making this volcano small compared to the general volcano, the largest volcano of the world, with only 25 centimetres of channel and the largest volcano with only 9 centimetres of diameter.
