Helens, other active Cascade volcanoes, and those of Alaska form the North American segment of the circum-Pacific "Ring of Fire," a notorious zone that produces frequent, often destructive, earthquake and volcanic activity.
He is presently employed in the Space & Atmospheric Sciences Group at the Los Alamos National Laboratory.Washington state's top polluter isn't a pulp mill, a power plant or refinery. Those emissions are so high that if the volcano were a new factory, it probably couldn't get a permit, Clint Bowman, an atmospheric physicist for the Washington Department of Ecology, told The Seattle Times. Since the volcano began erupting in early October, it has been pumping out 50 to 250 tons a day of sulfur dioxide, the lung-stinging gas that causes acid rain and contributes to haze. Helens, located in southwestern Washington about 50 miles northeast of Portland, Oregon, is one of several lofty volcanic peaks that dominate the Cascade Range of the Pacific Northwest; the range extends from Mount Garibaldi in British Columbia, Canada, to Lassen Peak in northern California. Helens a composite volcano (or stratovolcano), a term for steepsided, often symmetrical cones constructed of alternating layers of lava flows, ash, and other volcanic debris.Composite volcanoes tend to erupt explosively and pose considerable danger to nearby life and property.Due to this, the study of volcanoes and the service that volcanologists provide to the public by way of information and predictions on activity is immeasurable....[tags: destructive force, volcanic eruption] - Myths and legends are everywhere. Wiens has a Ph D in Physics, with a minor in Geology.His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.In addition to sulfur dioxide, volcanoes also release smaller amounts of other noxious gases, including hydrogen sulfide and hydrogen chloride.They also release carbon dioxide, the greenhouse gas that's primarily blamed for global warming. Helens produces between 500 and 1,000 tons a day of carbon dioxide, Gerlach estimates.
