USGS: Volcano Hazards Program

Sulfur dioxide is a colorless gas with a pungent odor that irritates skin and the tissues and mucous membranes of the eyes, nose, and throat. SO 2 emissions can cause acid rain and air pollution downwind of a volcano—at Kīlauea volcano in Hawaii, high concentrations of sulfur dioxide produce volcanic smog (VOG) causing persistent health problems for downwind populations.

USGS: Volcano Hazards Program

Sulfur dioxide indicates magma is near the surface. Sulfur dioxide (SO 2) is released from a volcano when magma is relatively near the surface. If SO 2 is detected at a non-erupting volcano, it could be a sign that it will erupt soon. By monitoring the amount of SO 2 being emitted from an active volcano, it is possible to calculate the amount of magma that is supplying the eruption.
