Volcanic-gas plume rises from Halema‘uma‘u Crater, Kīlauea Volcano,...

Detailed Description

A plume of volcanic gases (chiefly water vapor, carbon dioxide, and sulfur dioxide), tiny lava and rock particles, and droplets drifts southwest in the tradewinds from Halema‘uma‘u Crater. The 500-5,000 metric tons (1.1-11 million pounds) of sulfur dioxide gas emitted each day react in the atmosphere and, with the other gases and particles, form "vog" (volcanic smog) downwind. The plume and vog can be harmful to humans, agricultural crops, and machinery.
