Symonds, Rose, Bluth, Gerlach (1994) have reported on the concentrations of various gases present in volcanic emanations for three volcanoes: Kilauea, Erta` Ale, and Momotombo. These gases typically include water vapor (H20), and, in order of their occurrence by volume, carbon dioxide (C02) and sulfur dioxide (S02). In addition, volcanoes are also known to release small amounts of several other gases, among them hydrogen sulfide (H2S), hydrogen (H2), carbon monoxide (CO), hydrogen chloride (HCL), hydrogen fluoride (HF), and helium (He). The United States Geological Survey, in a web site describing volcanic gases (2006), includes some of the data provided by…

Sanford is an Adjunct Professor of Geology. When not teaching classes, looking for oil (in the subsurface!), or solving the world's environmental problems, he attempts to right every wrong (as far as the application of the scientific method is concerned), and otherwise keep his bow into the waves. If all else fails, there is always a night at the Opera, or a quiet time at the local coffee house.
