Kīlauea erupted again — and stopped again. Episode 44 of lava fountaining in Halemaʻumaʻu ran from 11:10 a.m. to 7:41 p.m. HST on April 9, 2026 — 8 hours and 31 minutes of continuous fountaining from the north vent, with lava reaching 800 feet (240 meters). The south vent never fountained but displayed periodic gas jetting and flames. The plume reached 16,000 feet above sea level, and southerly winds pushed tephra north — pieces of lightweight reticulite up to 12 inches hit the Volcano Golf Course subdivision, and fine ash and Pele’s Hair reached as far as Hilo.

This was a smaller eruption than Episode 43 on March 10, which set a cycle record with a 1,770-foot south vent fountain and 4–12 inches of debris — but the steady winds during Episode 44 created a similar tephra fallout pattern. The eruption is now paused, and as of April 13 USGS HVO has stepped the alert level down from WATCH/ORANGE to ADVISORY/YELLOW — still elevated unrest, but a longer quiet interval than earlier pauses in this cycle. For summer visitors planning a Big Island trip, this eruption cycle is both a safety consideration and — for those who plan around it — one of the most spectacular natural shows on Earth.

Two vents in the Halemaʻumaʻu crater — one on the north side, one on the south — have been alternating between eruption and pause since late 2024. During active episodes, lava fountains erupt from one or both vents, filling the crater floor with fresh lava and sending tephra (volcanic rock fragments) into the air.

The March 10 episode (Episode 43) was the most powerful in the current cycle, with the south vent fountain reaching a record 1,770 feet. Lava fountained for about nine hours from both vents, and the eruption column launched material high enough for NASA satellites to capture. Communities downwind, including parts of Volcano Village, received a coating of Pele’s hair (thin volcanic glass fibers) and small cinder.

Episode 44 began at 11:10 a.m. HST on April 9, almost exactly a month after Episode 43. The north vent reached a peak of about 800 feet around 1 p.m., then gradually diminished until the eruption ended at 7:41 p.m. Southerly winds pushed the plume and tephra north — with reticulite pieces up to 12 inches reported near Kīlauea Military Camp and the Volcano Golf Course, and fine ash reaching Hilo. The eruption was smaller than Episode 43, but the steady winds produced a similar tephra footprint. Report tephra fall at hawaiiash.science.

The honest answer: probably, but no one can guarantee it. Kīlauea has sustained episodic eruption cycles lasting months to years in the past. The current cycle shows no signs of winding down. Magma supply to the summit reservoir remains robust, and the pattern of deflation-inflation-eruption has been remarkably consistent since December 2024.

For summer visitors, this means there is a reasonable chance of witnessing active lava on any given Big Island visit between June and August 2026. But “reasonable chance” is not “certainty.” Eruptions can pause for weeks, and there is always the possibility the cycle ends between episodes. The Big Island has plenty to offer even without visible lava — but if timing your trip around the eruption matters to you, monitor the USGS Kīlauea update page in the weeks before your trip.

The park is open. That is the most important thing for visitors to understand. Hawaiʻi Volcanoes National Park does not close during summit eruptions. Specific overlooks or trail segments near the crater may close temporarily during active fountaining events, but the vast majority of the park — including the Crater Rim Drive, Kīlauea Iki Trail, Thurston Lava Tube, and Chain of Craters Road — remains accessible.

Keanakakoi Overlook and Uēkahuna offer the most direct sightlines into Halemaʻumaʻu when they are open, but both have cycled between open and closed for tephra cleanup after each recent fountaining episode — rangers reported softball-sized chunks landing near Kīlauea Military Camp during Episode 44. Check the NPS conditions page the day of your visit. After dark, the lava glow from the active lake and spattering is visible from multiple overlooks along Crater Rim Drive. On clear nights during active episodes, the sky above the crater turns orange — visible from miles away.

Park entrance fee: $30 per vehicle (valid for 7 days). Annual pass holders enter free. The park is open 24 hours — nighttime visits during eruptions are common and encouraged by rangers.

Air quality matters. Vog (volcanic fog) and SO₂ emissions increase during eruptions. People with respiratory conditions should check current air quality conditions on AirNow before visiting. On high-emission days, rangers may restrict access to downwind areas. Healthy adults generally tolerate normal vog levels without issues, but bring water and do not push through if breathing feels labored.

From the crater rim (free). The overlooks along Crater Rim Drive are the easiest and cheapest way to see the eruption. During active episodes, fountains are visible in daylight. Between episodes, the lava lake and spattering are best seen after sunset when the glow stands out against the dark sky. Dress warm — the summit sits at 4,000 feet and temperatures drop into the 50s at night.

By helicopter. A helicopter flight over an actively erupting Kīlauea is one of the most dramatic experiences on Earth. Pilots know the eruption status in real-time and adjust routes accordingly. Even between episodes, the steam plumes, fresh lava flows, and crater topography are striking from the air. Paradise Helicopters and Blue Hawaiian both offer volcano-focused routes from Hilo. See our helicopter tour guide for details, or book Big Island helicopter tours on Viator.

From Volcano Village. The small community of Volcano, located just outside the park entrance, offers a base camp for eruption viewing. Several B&Bs and vacation rentals put you within a 5-minute drive of the crater rim overlooks — useful for catching nighttime eruption events without a long drive from Kona or Hilo.

The eruption is contained to the summit crater. Lava is not flowing into communities or crossing roads. The current eruption cycle is confined to Halemaʻumaʻu crater within the park. There is no lava reaching the ocean and no lava flow threatening infrastructure. The 2018 lower East Rift Zone eruption that destroyed homes in Leilani Estates was a fundamentally different event. This is a summit eruption — spectacular to watch, but geographically contained.

Tephra fall is the main hazard. During high-fountaining episodes, volcanic rock fragments (tephra) can fall on areas downwind of the crater, including sections of Highway 11 and Volcano Village. After Episode 43, accumulation reached 4-12 inches in some spots. If you are visiting during an active episode, keep car windows closed when driving near the park and avoid breathing in volcanic dust.

Stay on marked trails and behind barriers. Ground near the crater edge can be unstable and undercut by lava tubes. The NPS marks closed areas clearly. Ignoring closures at an active volcano is not adventurous — it is how people die.

Flying in and out of Hilo is unaffected. Hilo International Airport operates normally during summit eruptions. Vog can reduce visibility on some days, but commercial flight operations continue. Kona airport on the west side is even further removed from the eruption.

Planning to drive around the Big Island? A rental car is essential — the park is about 45 minutes from Hilo and 2.5 hours from Kona.

No. Unless you have a severe respiratory condition that makes vog exposure medically risky, there is no reason to avoid the Big Island because of the eruption. The opposite is true — an active eruption makes the Big Island visit more memorable, not less. Visitors who happen to be on-island during an active episode get to witness something most people only see on documentary footage.

If anything, build flexibility into your itinerary. Keep one evening open for a nighttime crater rim visit in case an episode kicks off during your trip. The USGS posts updates multiple times daily, and the eruption cycle has been regular enough that the forecast windows are surprisingly accurate.

Summer 2026 on the Big Island is shaping up to be one of the more exciting volcanic seasons in recent memory. Plan for it.
