Helens erupted in Washington, spewing ash, rock and hot gases into the air and causing mud to flow down the mountain sides.
USA TODAY Network takes a look at the natural disaster by the numbers. Helens erupted in Washington, spewing ash, rock and hot gases into the air and causing mud to flow down the mountain sides. PDT and was "the deadliest and most economically destructive volcanic event in the history of the United States," according to the National Oceanic and Atmospheric Administration.
Between half and two thirds of Adams is within the Mount Adams Wilderness of the Gifford Pinchot National Forest.
The remaining area is within the Mount Adams Recreation Area of the Yakama Indian Reservation.
CDIAC's data holdings include estimates of carbon dioxide emissions from fossil-fuel consumption and land-use changes; records of atmospheric concentrations of carbon dioxide and other radiatively active trace gases; carbon cycle and terrestrial carbon management datasets and analyses; and global/regional climate data and time series.
CDIAC provides scientific and data management support for numerous projects including large-scale DOE ecosystem experiments like the Next-Generation Ecosystem Experiments; the Ameri Flux Network, continuous observations of ecosystem level exchanges of CO measurements taken aboard ocean research vessels; and the HIPPO project, which measured and is analyzing the atmospheric carbon cycle and greenhouse gas concentrations from pole to pole over the Pacific Ocean.
Helens, and it sits in the middle of a heavily populated area. Kilauea Volcano on Hawaii's Big Island churns out 2,000 tons a day of sulfur dioxide when it's erupting, creating an acid fog that damages local crops. Helens hasn't been as noticeable, but, Gerlach said, "If you were to go and collect rainwater just downwind of the volcano, I suspect you would see some acid rain." Worldwide, sulfur dioxide emissions from volcanoes add up to about 15 million tons a year, compared to the 200 million tons produced by power plants and other human activities.
While volatiles trapped in the remaining crustal residue are ultimately assimilated into the mantle, lighter volatiles from the crustal melt are fractionated and float up towards the surface to feed plate margin volcanoes.
A brief survey of the literature concerning volcanogenic carbon dioxide emission finds that estimates of subaerial emission totals fail to account for the diversity of volcanic emissions and are unprepared for individual outliers that dominate known volcanic emissions.
Deepening the apparent mystery of total volcanogenic CO emission and fossil fuel consumption that are, to date, unquantified.
But persons with sensitive breathing ailments probably would feel the effects if they lived close to it, said Bob Elliott, executive director of the Southwest Clean Air Agency in Vancouver.
"We are very fortunate, in terms of the impact on human health, that Mount St. Not smog, but vog Italy's Mount Etna can produce 100 times more sulfur dioxide than Mount St.
