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.

About 7,000 big game animals lost In addition to human lives lost, an estimated 7,000 big game animals – such as deer, elk and bears – were also killed. The first animals to return to the eruption area were spiders and beetles.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.The "solid earth", a term popular amongst climatologists, is a deceptive misnomer as the aesthenosphere is a deeply convecting fluid upon which flexible sheets of crust (i.e. This deeply convecting fluid tears these delicate plates apart at rift zones and crushes them together like the bonnet of a wrecked car at convergence zones.Mountains rise out of fold belts resulting from the crumpling of plates, and where differences in plate buoyancy allow, one plate rides over another, forcing the other plate to follow the convection current into the aesthenosphere.
