Join three USGS–Hawaiian Volcano Observatory scientists as they embarked on a helicopter mission to the northwestern wall of Halema‘uma‘u at Kīlauea’s summit on July 2, 2026. Their goal was to sample tephra deposits from the crater wall, which had been inaccessible before now. As lava flows have filled in... Halemaʻumaʻu, the floor of the crater has risen but the deposits, records of past explosive eruptions in Kīlauea's history, could be covered by lava flows in the future. These samples were collected with permission from Hawai'i Volcanoes National Park and will help us better understand eruption behavior, magma storage, and volcanic hazards. 🛰️ This behind-the-scenes glimpse highlights the sampling mission in Halema'uma'u on July 2, 2026. #Kilauea #Tephra #Hazardsshow more

Lava fountained for nearly 13 hours on August 22-23 during episode 31 of the ongoing eruption at the summit of Kīlauea volcano on the Island of Hawaiʻi. USGS Hawaiian Volcano Observatory scientists documented the eruptive episode, which included a lava fountain that extended 1,000 ft (300 meters) from the north vent, feeding a lava channel and depositing tephra on the floor of Halemaʻumaʻu crater. The south vent and additional intermediate vents also erupted during this episode. With the permission of Hawaiʻi Volcanoes National Park, USGS scientists conducted a monitoring overflight of the eruption site on August 25, during which they visited the floor of Halemaʻumaʻu crater to collect a sample of material erupted during episode 31. Geochemical analysis of the sample will help scientists to understand the processes driving this episodic eruption that has been occurring since December 23, 2024. #usgs #Kilauea #HVO #lava

Episode 32 of Kīlauea’s ongoing summit eruption, on the Island of Hawaiʻi, began this morning, September 2, at 6:35 a.m. Hawaii Standard Time. Current fountains are about 500 feet (150 meters) high and arcing into Halemaʻumaʻu crater. According to the National Weather Service, winds are blowing from the northeast direction today, which suggests that volcanic gas emissions and volcanic material will be distributed to the southwest of Halemaʻumaʻu crater and vog may impact communities to the south and west of Kīlauea's summit. All eruptive activity is confined to Halemaʻumaʻu crater within Kaluapele (Kīlauea summit caldera) in Hawaiʻi Volcanoes National Park.

By request, we’re sharing more footage taken during the recent overflight of Kīlauea volcano’s summit eruption site on the Island of Hawai‘i. The USGS Hawaiian Volcano Observatory conducted the monitoring overflight of Halema‘uma‘u crater yesterday morning, December 2, 2025. With permission from Hawai‘i Volcanoes National Park, scientists visited the crater floor to collect a sample of episode 37 lava and to take visual/thermal imagery that will allow us to map the distribution of material erupted during episode 37 (lava flows and tephra). Lava fountained only from the north vent during episode 37, for about 9 hours on November 25. The summit region of Kīlauea volcano has shown inflationary deformation since the end of episode 37, suggesting that another eruptive episode is possible. Modeling shows that episode 38 could occur between December 6-10. #Kilauea #lava

From coverage to clean up, eruption to restoration🌋 Episode 41 of the Kīlauea summit eruption sent tephra raining down on Uēkahuna overlook in Hawaiʻi Volcanoes National Park. By the next morning, park staff had cleared the fallout. What's tephra? It's what you call any material that erupted by a volcano and traveled through the air before landing on the ground. During lava fountaining episodes at the summit of Kīlauea, tephra ranges in sizes from volcanic ash to Pele's hair (strands of volcanic glass) to pieces of glassy reticulite (a lightweight frothy rock full of bubbles). 📷Timelapse captured by the USGS Hawaiian Volcano Observatory K2cam (note that overnight section was sped up 4X faster compared to rest of video). #Kilauea #NPS #tephra #volcano #lava

Glimpse into the eruptive vents at Kīlauea summit as we await the start of episode 50 of lava fountaining. This video was taken during a misty USGS Hawaiian Volcano Observatory monitoring overflight on June 24, with views accompanied by a rainbow (ānuenue). • Aerial views into the north and south vents show them steadily emitting volcanic gases. Magma is visible roiling within the bifurcated interior of the north vent. • With permission from Hawaiʻi Volcanoes National Park, USGS scientists briefly landed on Halemaʻumaʻu crater floor to collect warm lava samples from episode 49, which will provide data on magma chemistry and underground storage conditions. • The onset of episode 50 of lava fountaining at Kīlauea summit is likely between June 25 and June 27, with June 26 most likely. Continuous strong glow was visible on webcams from both vents in Halemaʻumaʻu overnight. The south vent continued to produced large flames caused by the burning of gas within the top of the conduit. Magma is close to the surface, visible within the north vent during the overflight on June 24. 🎥: Videos of Kīlauea summit taken during helicopter overflight on June 24, 2026. #Kilauea #HVO #Rainbow

Kīlauea Eruption Episode 46 Update May 5, 2026, 11:30 am HST Episode 46 of lava fountaining in Halemaʻumaʻu at the summit of Kīlauea began at 8:17 a.m. HST on May 5 and continues at this time. Lava fountains from the north vent are currently reaching 650 feet (200 m) above ground level and the eruptive plume is reaching 20,000 feet (6,000 m) above sea level. Lower-level winds from the southeast distributed some tephra to the northwest in the first hours of the eruption. First-sized and smaller clasts were reported at Uēkahuna overlook in Hawaiʻi Volcanoes National Park and between mile markers 31 and 32 on Highway 11. Hawaiʻi Volcanoes National Park temporarily closed some overlook areas on the west rim of the caldera, but Highway 11 remains open. Fallout in these areas has since decreased and the USGS is keeping Kīlauea Volcano Alert Level at WATCH and the Aviation Color Code at ORANGE. Higher-level winds are southwesterly, which suggests that the plume and tephra may be transported to the northeast with time as the eruption continues and the plume develops. The National Weather Service Ashfall Advisory remains in effect.

🚨#BREAKING: Kilauea Volcano has just begun to produce Massive Lava Fountains reaching hundreds of feet in the air inside the volcano’s crater 📌#Hawaii | #USA At this time Hawaii’s Kilauea volcano, one of the world’s most active volcanoes, has just begun erupting, sending massive lava fountains soaring hundreds feet into the air inside Halemaʻumaʻu Crater on the Big island in Hawaii. The eruption is producing intense heat, glowing rivers of molten rock, and billowing plumes of volcanic gas. Officials have issued a warning urging people near the volcano to exercise caution due to the release of toxic gases and ongoing lava flows. While the eruption is being closely monitored, there is currently no immediate threat to the public.

Kīlauea Eruption Update — Episode 49 of Kīlauea summit lava fountaining began at 9:32 a.m. HST today, June 14, and is ongoing. This eruption is taking place within Kīlauea summit caldera in Hawai‘i Volcanoes National Park. Precursory lava flows began from the north vent at 4:10 a.m. this morning. After a few intermittent overflows from both the north and south vents, a constant dome fountain began at the north vent at about 8:15 a.m., gradually building into the main fountaining. Only the north vent has been active during the episode thus far, and the maximum fountain height was about 690 feet (210 meters), occurring about an hour into the episode. National Weather Service has issued an ashfall advisory for the areas to the southwest of Halemaʻumaʻu based on wind conditions and the potential for tephra fallout. Fountaining episodes typically last 12 hours or less, but ash can remain in the air for longer depending on wind and weather conditions. Please stay aware of hazards and rely on official updates from USGS, National Weather Service, and Hawai’i Volcanoes National Park. 🎥 Video of episode 49 on June 14, 2026, by Heather Winslow. #Kilauea #Eruption #Lava

USGS Hawaiian Volcano Observatory geologists observed lava roiling in the north and south vents at the summit of Kīlauea on Friday, November 21. Shortly after, lava flowed onto Halemaʻumaʻu crater floor for the first time since episode 36 (November 9). That activity continued through the weekend, with 73 overflows total. Over the past 24 hours, Kīlauea summit deflated and the overflows stopped, causing the forecast window for episode 37 to be adjusted slightly later in time. Episode 37 could occur anytime this Thanksgiving week.

This eruptive episode began from the north vent at about 8:45 am HST this morning, December 6. Smaller fountains began from the south vent at 8:49 am HST and quickly grew to over 1000 feet (300 meters) high and inclined to the south, towards a closed area of Hawaiʻi Volcanoes National Park. At 9:55 a.m., hot tephra falling from this fountain destroyed the V3 streaming camera site located within less than a mile (2,000 ft/500 m) from the eruptive vents; its burial highlights the hazardous nature of this closed area. The north vent stopped erupting at 11:50 a.m., but the south vent is still fountaining as of this posting. In addition to the tephra, volcanic gas is being emitted, with sulfur dioxide emission rates likely exceeding 50,000 tonnes per day. The high effusion rate of this episode is also producing a very dramatic plume extending over 20,000 feet above sea level. Both the National Weather Service and Washington Volcanic Ash Advisory Center issued special advisories about this plume, and the Hawaii County Civil Defense Agency issued a message about the potential for fine glass particles in communities downwind. Kīlauea's recent eruptive episodes have gone on for 5-9 hours; this episode has been active for about 4.5 hours now. The USGS Hawaiian Volcano Observatory staff are closely monitoring this activity, coordinating with partners at Hawaiʻi Volcanoes National Park and the Hawaii County Civil Defense Agency. #Kilauea #lava #eruption

Episode 54 of the Kīlauea summit eruption happened yesterday, August 25, on the 110th birthday of the National Park Service! ⏰ Lava fountained only from the north vent for 9 hours, from 10:30 a.m. to 7:33 p.m. HST. 📏 The north vent lava fountain reached a maximum height of about 500 feet (150 meters), similar to several of the past recent episodes. 💨 Winds were out of the northeast causing the plume, which reached about 17,000 feet (5,200 meters) above sea level, to move to the southwest with most tephra falling in the closed area of Hawaiʻi Volcanoes National Park. 💥 An estimated 5.2 million cubic yards (4.0 million cubic meters) of lava erupted in total, covering about 30% of Halemaʻumaʻu crater floor. ⛔️ Kīlauea alert level/aviation color code was at WATCH/ORANGE throughout the episode and lowered to ADVISORY/YELLOW when the episode ended. Inflation has resumed following the end of the episode, so another fountaining episode is likely in the coming weeks. 📹 Video clips show Kīlauea episode 54 lava fountaining on August 25, 2026. #Kilauea #Lava #Eruption

Kīlauea’s summit eruption Episode 46 ended at 5:22 pm HST on May 5 after 9 hours of lava fountaining. 🌋 Only the north vent fountained, reaching heights of 650 ft (200 m). About 6 million cubic yards of lava covered over half of Halemaʻumaʻu’s crater floor. 💨 The plume rose to 20,000 ft (6,000 m), with tephra falling N-NW and NE of the crater. Fist‑sized fragments reached areas along the north caldera rim and Highway 11. Pele’s hair was reported in Volcano Golf Course and Mountain View. ⛔️ USGS maintained WATCH/ORANGE during the episode and lowered to ADVISORY/YELLOW afterward. NWS issued an ashfall advisory for S/SE Hawai‘i Island. Kīlauea summit inflation after Episode 46 suggests another fountaining episode is possible, but more data is needed before forecasting Episode 47. 📹 Views of episode 46 on May 5, 2026. #Kilauea #Lava #Eruption

Time for an aerial tour of Mount St. Helens! Summer has arrived, and that means field work in the Cascades. On Wednesday, June 24, teams from the Cascades Volcano Observatory were at Mount St. Helens to swap batteries, upgrade GPS sites, solidify solar power systems, remove legacy equipment, and survey river channels for changes. Along the way, one of the field crews captured this aerial video of the crater of Mount St. Helens. The helicopter flies up the western arm of the Crater Glacier, past the 1980-86 lava dome, and then swings to the left around the still-steaming 2004-08 lava dome to get a view to the north out of the crater at Johnston Ridge, Spirit Lake, and Mount Rainier in the distance. Cascades Volcano Observatory update for Friday, June 19, 2026: All volcanoes in the Cascade Range of Oregon and Washington were at normal background levels of activity for the last week. Small earthquakes were detected at Mount Rainier and Mount St. Helens. 📽️: USGS video from helicopter flight into Mount St. Helens Crater by Marco Bagnardi, June 24, 2026.
