The absence of visible lava at the surface does not equate to inactivity, as magma continues to move slowly within the deeper plumbing system. Sulfur dioxide (SO₂) plumes, while often invisible, can create hazardous air quality conditions in downwind communities, particularly in the Puna district.

Sulfur dioxide (SO₂) levels can fluctuate rapidly with changes in volcanic activity. Wind patterns play a crucial role in dispersing volcanic gases across the island.
Current Status of Kīlauea Volcano As of the latest monitoring data, Kīlauea is experiencing a period of relative calm following the eruption that reshaped its summit landscape. 5) can exacerbate respiratory conditions for sensitive groups.
