Onset of huge Episode 41 lava fountains at Kīlauea summit heralds ashfall warning | Big Island Now
This story was updated at 1:30 p.m. Saturday, Jan. 24, 2026, with updates about highway and park closures because of the ashfall from Episode 41 of the ongoing Kīlauea summit eruption.
Episode 41 of lava fountaining to more than 1,600 feet high as part of the ongoing episodic summit eruption of Kīlauea volcano — within Halemaʻumaʻu Crater inside the summit caldera at Hawaiʻi Volcanoes National Park — began at 11:10 a.m. today (Jan. 24), bringing with it the threat of significant ashfall for much of the island.
National Weather Service forecasters in Honolulu first issued an ashfall advisory but then later upgraded it to an ashfall warning — in effect until 6 a.m. Sunday (Jan. 25) — for most eastern, southeastern, southern and interior portions of the island.
Hawaiʻi County Civil Defense reports that Hawaiʻi Police Department says Highway 11 is closed in both directions near the 24.5-mile marker at the solid waste transfer station and at the 32-mile marker in Hawaiʻi Volcanoes National Park in Puna and Kaʻū because of ashfall.
Hawaiʻi Volcanoes National Park is also closed at this time.
Motorists should avoid the area and use alternate routes. Updates will be issued as conditions change.
“Kilauea is undergoing a eruption and we have received reports of moderate ashfall and significant amounts of tephra,” says the Honolulu forecast office warning. “We have also received reports of debris as large as a foot near Kīlauea. Satellite imagery shows a large volcanic plume drifting towards [the] Glenwood and Pāhoa area.”

Disruption of services and utilities — including water, sewer and electric — is possible. Ash removal efforts also could become significant.
Forecasters advise the public to:
- Seal windows and doors.
- Protect electronics.
- Cover air intakes and open water sources.
- Avoid driving.
- Remain indoors unless it is absolutely necessary to go outside.
- Use extreme caution clearing rooftops of ash.
- Listen for further announcements.
Hawaiian Volcano Observatory reports tephra fall was reported in public viewing areas within Hawaiʻi Volcanoes National Park, Volcano Village, Mauna Loa Estates and ʻŌhiʻa Estates in Puna.
North and south vent fountains were higher than 1,640 feet tall — the highest recorded since the eruption started more than a year ago — as of 12:10 p.m.
Hawaiian Volcano Observatory reports ground-level sensors near the eruptive vents in the southwest portion of Halemaʻumaʻu Crater indicate winds are light and blowing from the south-southeast, which suggests volcanic gas emissions and volcanic material could be distributed to the north and northwest of Halemaʻumaʻu.
Winds also are forecast to be light and variable during the next several hours.
The plume in past episodes reached up to or above 20,000 feet above ground level, driven by incandescent lava fountains up to or higher than 1,500 feet.
Most volcanic ash and pumice — also known as tephra — typically falls within about 1 mile of the eruptive vents during eruptive episodes.
Lower concentrations of finer volcanic particles — such as ash and the fine glass strands called Pele’s hair — can be transported greater distances downwind of the vent, however, sometimes up to 20 miles.
Sulfur dioxide emission — the main driver of volcanic fog, or vog — is typically 50,000 to 100,000 tonnes per day during an eruptive episode.
All eruptive activity is confined to Halemaʻumaʻu crater in Hawaiʻi Volcanoes National Park.
Most lava fountaining episodes since the eruption started Dec. 23, 2024, continued for a day or less.
KPcam and MKcam provide views of the plume height, and there are three webcams that provide livestream video showing eruptive lava fountains at the Kīlauea summit.
Additional short updates as Episode 41 progresses will be posted on the Hawaiian Volcano Observatory website.
You can contact the observatory via email at askHVO@usgs.gov for additional information or with any questions. Also, be sure to visit the Hawaiʻi Volcanoes National Park website before you go.
No changes have been detected in the East Rift Zone or Southwest Rift Zone.
Kīlauea’s Volcano Alert Level remains at Watch and its Aviation Color Code is still at Orange.
Hawaiian Volcano Observatory continues to monitor Kīlauea volcano closely and will update the public if and when any changes to eruptive activity happen.

Towering lava fountains of Hawaii’s Kilauea volcano trigger park and highway closures
HONOLULU — The latest lava fountaining episode of an erupting Hawaii volcano reached 1,000 feet high Tuesday, prompting temporary closures at a national park and part of an important highway because of falling glassy volcanic fragments, including ash.
Kilauea, on Hawaii’s Big Island, has been dazzling residents and visitors for more than year with an on-and-off eruption that periodically sends fountains of lava soaring into the sky.
The fountaining that began Tuesday morning marked the eruption’s 43rd episode since it began in December 2024. A livestream showed two fountains of bright-red lava and smoke. It’s unclear how long the fountaining will last. Some episodes have lasted a few days and others a few hours.
Like other times, the molten rock was confined within Kilauea’s summit crater inside Hawaii Volcanoes National Park and hasn’t threatened homes or buildings.
But the lava fountains were creating trouble for neighboring communities and a highway where the volcanic fragments and ash, known as tephra, was falling. The tephra prompted temporary closures at the national park around the summit and a partial closure of Highway 11, an important route around the island, on either side of the park.
Hawaii County officials also opened a shelter at a district gymnasium for residents and tourists impacted by the road closure or falling tephra. There were no people using the shelter soon after it opened, said Tom Callis, a county spokesperson.
The National Weather Service issued an ashfall warning.
Volcanic tephra can irritate eyes, skin and the respiratory system, according to county officials. Tephra also can clog and cause other problems with water catchment collection systems, which are common in some parts of the Big Island, officials said.
Ash fell so heavily during a previous fountaining episode that some communities needed help from county civil defense workers to clean up ash that coated their homes, Callis said.
Kilauea is one of the world’s most active volcanoes.

Episode 43: Volcano Warning issued for Kilauea due to falling ash and tephra
HAWAII VOLCANOES NATIONAL PARK (HawaiiNewsNow) – The U.S. Geological Survey has upgraded the Kilauea alert level to a Volcano Warning due to fallout of the latest high-fountaining at Halemaumau crater.
The National Weather Service also issued an ashfall warning until 5 p.m. Tuesday for Hawaii Volcanoes National Park and communities to the northeast, including Volcano, Glenwood and Mountain View.
Episode 43 began Tuesday at 9:17 a.m. HST with more than a quarter-inch of accumulated tephra, including ash and other volcanic particles, reported within the first 90 minutes.
The USGS said fallout up to the size of footballs was reported at lookouts within Hawaii Volcanoes National Park, creating hazardous ground conditions.
The National Weather Service said the plume from this episode rose to 25,000 feet. Surface level winds are reported coming from a southerly direction, which means that volcanic gas emissions and fallout may be distributed to areas northeast of the summit.
Communities adjacent and downwind of the eruption need to take necessary precautions for elevated tephra fallout and volcanic gases.
Closures in effect, shelter open
Highway 11 is closed on either side of Hawaiʻi Volcanoes National Park (HVNP) at mile markers 24 and 40. HVNP is also closed.
The County of Hawaiʻi has opened a shelter at Kaʻū District Gym, 96-1219 Kamani St., Pāhala, for residents and visitors impacted by the road closure or falling tephra.
Safety information
Volcanic tephra, including ash, can irritate eyes, skin, and the respiratory system. Take necessary precautions to limit exposure.
- If you have a respiratory condition, avoid contact with ash. Stay indoors until it is safe to go outside.
- Close doors and windows, where possible.
- Wear masks, gloves and eye protection when in contact with ash.
- Do not drive in heavy ashfall.
Tephra also can clog and cause other problems with water catchment collection systems.
- Temporarily disconnect the gutters feeding into the tank. Do not reconnect the system until the volcanic hazards (i.e. ash, laze, Pele’s hair in the air) have passed and the ash and debris are washed off the roof, out of the gutters and the tank.
Use caution when clearing rooftops of ash.
Road closures may occur without warning.
