Scientists have discovered a new kind of hot spring - the terrestrial smoker.
The hot spring was discovered along the banks of a crater lake inside the Taal Volcano in the Phillipines, and scientists speculate terrestrials smokers may exist near other volcanoes all over the world.
Terrestrial smokers may account for missing parts of the “heat budget” for volcanoes. Accounting for heat may help scientists predict eruptions.
Cool water from the leak seeps into the lake bed near the shore, where it mixes with hot water from the spring, which then rises back to the surface, creating convection cells. The contents of the lake are recycled in a matter of days through the convection cells.
The spring appears invisible to the naked eye, but infrared video shows the circulation of hot and cold water.Read more at University of Texas at Austin
