Archive note: This page records conditions and trip-planning context from April 13, 2026. It is not a live eruption report. On August 29, USGS reported that Episode 54 had ended on August 25 and that the Halemaʻumaʻu summit eruption was paused. Read the August 29 USGS update. Check the latest USGS status information before making an eruption-viewing plan.

The Kīlauea Episode 44 eruption began at 11:10 a.m. HST on April 9, 2026, and ended at 7:41 p.m. It delivered 8 hours and 31 minutes of continuous lava fountaining from the north vent in Halemaʻumaʻu. USGS documented the episode timeline.

The north vent reached about 800 feet (240 meters) around 12:45 p.m. The south vent did not fountain, but it produced periodic gas jetting and flames. USGS reported both vent conditions. The plume rose to about 15,000 feet (4,500 meters) above sea level. Southerly winds carried tephra north of Halemaʻumaʻu. Lightweight reticulite pieces up to 12 inches landed near Kīlauea Military Camp and the Volcano Golf Course subdivision. USGS documented the reticulite fallout. Fine ash and Peleʻs hair were reported as far as Hilo.

Episode 44 was smaller than Episode 43 on March 10, which produced a 1,770-foot south-vent fountain, the tallest of this eruption cycle. Episode 43 also left tephra up to a foot deep at Uēkahuna. NPS documented that cleanup. USGS described Episode 44’s fallout pattern as similar to Episode 43’s, but not as thick. Read the Episode 44 USGS report. When it ended, USGS lowered Kīlauea’s status to ADVISORY/YELLOW, reflecting lower ground and aviation hazards during a pause between episodes. Read the April 13 USGS update.

The summit eruption began on December 23, 2024. By Episode 44, it had used north and south vents in Halemaʻumaʻu. An episode could erupt from one vent or both, laying fresh lava across the crater floor and throwing tephra into the air. USGS explains the summit-eruption pattern.

The pattern resembled a pressure gauge cycling through the same hard swing. Before an episode, the summit inflated. It deflated while lava fountains, then began inflating again after activity stopped. USGS said the cycle could continue while summit pressure conditions persisted, but a blocked vent or a shift in inflation could change it fast.

Episode 43 showed how large that swing could become. NASA satellite imagery captured the drifting plume and heat from fresh lava after that event. See NASA’s imagery and account. If tephra falls where you are staying during a future episode, report it at hawaiiash.science.

On April 13, no one could promise that Kīlauea would erupt during a particular summer trip. Documented post-2018 summit eruptions had lasted from about one week to more than a year, and Kīlauea had produced episodic fountaining cycles before. USGS documents that post-2018 range.

Since December 2024, the summit had repeatedly inflated before fountaining, deflated during episodes, and resumed inflation afterward. USGS said that pattern might continue while pressure conditions persisted, but it could change or end. My planning rule remains simple: treat active lava as a possible bonus, not a guaranteed part of an itinerary.

This was April trip-planning guidance, not a forecast that survived the summer. For a future trip, monitor the USGS Kīlauea update page before arrival and again while you are on the island.

Park access could change quickly during an eruption. Hawaiʻi Volcanoes National Park could remain partly open, but NPS could close affected summit areas when tephra or volcanic gas created a hazard. During Episode 43, NPS closed all outdoor overlooks and trails near the summit. Read the NPS closure notice. For a current visit, start with the Hawaiʻi Volcanoes National Park website, then check the NPS conditions page on the day you visit.

When west-side viewing areas were open, NPS identified Uēkahuna and Kīlauea Overlook as usual access points for eruption viewing. Check NPS eruption-viewing guidance before heading out. After dark, lava glow could be visible from authorized viewpoints during active or recently ended episodes. Weather and park access decided what visitors could actually see.

In April 2026, entry cost $30 per private vehicle, valid for seven consecutive days. Holders of a valid America the Beautiful annual pass or Hawaiʻi Tri-Park Annual Pass did not need to buy another park pass. NPS listed the park as generally accessible 24 hours a day, subject to closures.

Vog and sulfur dioxide could affect summit visitor areas during eruptive conditions. NPS could close impacted areas when hazardous vog or tephra persisted. Follow NPS volcanic-gas guidance. Check posted park alerts and current local air-quality conditions, follow restrictions, and leave if you develop breathing trouble.

During an active episode, authorized viewpoints near the summit were the simplest way to watch. Park admission covered viewing; there was no separate crater-rim viewing charge. Use the NPS conditions and eruption-viewing pages to confirm what is open before you drive up. After sunset, visible lava glow can stand out against the dark. Bring warm layers and rain protection because summit weather can turn quickly.

A helicopter flight can show the summit crater, steam plumes, and fresh lava terrain in one sweep. I would not book a flight expecting guaranteed active fountains. Weather, airspace restrictions, and the operator’s route control what is possible that day. Ask directly whether conditions may allow eruption viewing. Paradise Helicopters and Blue Hawaiian offer Hilo departures that include volcanic landscapes. See our helicopter tour guide for details, or book Big Island helicopter tours on Viator.

Volcano Village can be a practical overnight base for a park visit. Staying nearby can make an early start or a late viewing attempt easier, though the drive to an open overlook varies with your property and any closures. Confirm current park access before choosing lodging around eruption viewing.

During Episode 44, NPS stated that eruptive activity was confined to Hawaiʻi Volcanoes National Park and did not threaten homes or park infrastructure. Check the NPS eruption-viewing page for current conditions. This was not the same kind of event as the 2018 lower East Rift Zone eruption, which began in Leilani Estates and destroyed more than 700 structures. USGS documents the 2018 eruption.

During high-fountaining episodes, volcanic fragments can fall downwind of the crater. Episode 43 fallout reached parts of Highway 11 and nearby communities. USGS documented that fallout after Episode 43. Keep vehicle windows closed near active fallout and avoid breathing volcanic dust.

NPS warns of unstable cliff edges, ground cracks, volcanic gases, rockfalls, and changing ground conditions. Follow park safety rules. Stay on marked trails and behind barriers. Ignoring a closure at an active volcano can be fatal.

Episode 43 showed that ash and vog can disrupt flights into Hilo. Visibility, aviation restrictions, and airline decisions can also change quickly. NASA reported flight cancellations during that episode. See NASA’s account of that event. Check your airline and airport updates before leaving for Hilo or Kona.

Planning to drive around the Big Island? A rental car gives you flexibility if viewing access shifts during your trip. Allow extra time when weather or eruption-related closures affect the drive.

Do not change Big Island plans automatically. Change them if official closures, air-quality conditions, or your health make summit travel a bad call. Visitors with respiratory conditions should take vog warnings seriously and choose lower-exposure activities when conditions are poor.

Build flexibility into your itinerary. Keep an evening open for a possible crater-rim visit, but do not plan your entire trip around a predicted fountain episode. Check the USGS update page before travel, review NPS conditions the day you visit, and turn around if access or air quality changes.

An active eruption can add a rare view to a Big Island trip. I would never make it a promise the itinerary depends on.
