This annotated photograph shows the different size categories of tephra associated with recent lava fountaining episodes at the summit of Kīlauea. The inset photo on the bottom left shows the vesicular (bubble-rich) texture of most of these clasts. The smallest particles of tephra are volcanic ash, and they are smaller than 1/16 of an inch (2 mm).

USGS Hawaiian Volcano Observatory geologists captured this view during a morning helicopter monitoring overflight of Kīlauea summit caldera, Kaluapele, on the morning of February 4, 2026. Despite glow present on the USGS livestream cameras overnight, no lava or incandescent material was visible in the north (right) and south (left) vents. USGS photo by D. Downs.

USGS Hawaiian Volcano Observatory staff participated in a monitoring overflight of Kīlauea summit caldera, Kaluapele, the morning of February 4, 2026, to investigate and collect samples of the episode 41 lava flows that were emplaced on January 24, 2026. These lava flows covered most of the crater floor during the lava fountaining episode. USGS photo by D.

On December 9, USGS-Hawaiian Volcano Observatory geologists conducted an aerial overflight of Kīlauea summit region, following lava fountaining episode 38 of the Halemaʻumaʻu eruption on December 6. In this video, the line on the ground in the lower left portion at the start of the video shows the extent of tephra deposits created during episode 38.

The V3 camera was located on the south rim of Halema‘uma‘u crater at the summit of Kīlauea volcano on the Island of Hawai‘i. The camera, located in a hazardous closed area of Hawai‘i Volcanoes National Park, was buried by tephra from an inclined lava fountain between 9:55 and 9:57 am HST on December 6, during episode 38 that began this morning at 8:45 am.

Lava lake activity from inside Halema`uma`u Crater

Sounds of lava lake activity within Kilauea Volcano's summit vent inside Halema`uma`u Crater on the afternoon of February 14, 2011. The continuous "crashing wave" noise is the sound of churning lava as gases are released from the lake surface, which is in nearly constant motion.
