Plume rising from Halema‘uma‘u crater at Kīlauea volcano in the morning sun

On the morning of November 9, a wispy volcanic gas plume (lower left) was visible over Halema‘uma‘u crater, at Kīlauea summit. As the hot plume rose to meet the cool morning air, water vapor formed a cloud above the crater. USGS photo by J. Schmith.
