The area of the bank where you can see those gas bubbles is several hundred meters long. The gas bubbles are good to see and hear when the water level is calm. The cooling of magma in the deep ist the origin of this carbon dioxide springs. The name mofetta is applied to a volcanic discharge consisting chiefly of carbon dioxide, often associated with other vapours, representing the final phase of volcanic activity. A mofetta has a temperature well below the boiling point of water, though above the temperature of the surrounding air. A fumarole rich in in carbon dioxide is called a mofette. Fumarole are vents in the Earth’s surface from which volcanic gases are emitted. The major source of the gas bubbles emitted by fumaroles is groundwater heated by bodies of magma lying relatively close to the surface. Carbon dioxide, sulfur dioxide, and hydrogen sulfide are usually emitted directly from the magma. Fumaroles are often present on active volcanoes during periods of relative quiet between eruptions. They may persist for decades or centuries if they are above a persistent heat source or disappear within weeks to months if they occur atop a fresh volcanic deposit that quickly cools.
