This map shows the tephra fall associated with episode 41 of Kīlauea's episodic summit eruption, on January 24, 2026. Tephra is a generic word for any material erupted by a volcano that travels through the air before landing on the ground.

Tephra is a word that describes any material erupted by a volcano that travels through the air before landing on the ground. Volcanic ash is tephra particles that are less than 2 mm in size (less than 0.08 in).

A piece of reticulite, a very frothy type of tephra full of bubbles, remains perched on top of a Hapuʻu tree fern frond in Volcano Village on January 27, 2026. This material was erupted during episode 41 lava fountaining at the summit of Kīlauea on January 24, 2026. USGS photo by K. Mulliken.

Tephra fall from episode 41 of Kīlauea summit eruption included pieces of reticulite, frothy rocks full of bubbles made by gas within lava expanding (which drives the lava fountaining process). These pieces of rock are very lightweight and glassy, which makes them very easy to crush.

Tephra clean-up efforts on Highway 11, near the entrance to Hawaiʻi Volcanoes National Park, on January 26, 2026. Water was sprayed on the pavement before machinery scrubs the pavement to remove the tephra particles.

Timelapse video showing tephra cover to cleanup in Hawaiʻi Volcanoes National Park. Lava fountains during episode 41 of the Kīlauea summit eruption on January 24, 2026, covered the Uēkahuna overlook within Hawaiʻi Volcanoes National Park with tephra fallout. The next morning, Hawaiʻi Volcanoes National Park staff clean the tephra from the area.

This timelapse video shows Kīlauea summit eruption episode 41 on January 24, 2026, captured by a USGS Hawaiian Volcano Observatory research camera on the south rim of the caldera. Both the north and south vents erupted,and the black material in the foreground is falling tephra. USGS video.

Kīlauea began its 39th lava fountaining episode the night of December 23, one year to the day from when this eruption began. This view was taken from the publicly accessible viewing area on Crater Rim Drive near Keanakākoi Overlook within Hawaiʻi Volcanoes National Park.

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.

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.

Kilauea Volcano in Hawaii has experienced its first explosive eruption in more than 80 years and is now spewing noxious gas at 10 times the normal rate. John Eichelberger, head of the USGS Volcano Hazards Program, fills us in on the situation.
