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.
The volcano spawns acid rain and a type of bluish smog that volcanologists call vog, which can affect large swaths of Europe, said Terry Gerlach, a U. Volcanic gases bubble out of magma as it rises to the surface, and the amount and type of emissions depend on the chemical makeup of the molten rock.
