🌋Kīlauea eruption episode 48 summary - a historic new record for Kīlauea! Episode 48 of the Kīlauea summit eruption in Hawai‘i Volcanoes National Park stopped at 1:37 pm HST June 1 after 9 hours of lava fountaining. This eruption has now surpassed the number of fountaining episodes in the opening years of the Puʻuʻōʻō eruption from 1983-1986 (47), setting a new record number of fountaining episodes in any one Kīlauea eruption. 🌋 Lava flowed from the south vent about 95 times in the days before episode 48, but only the north vent produced a lava fountain (up to 650 ft/200 m) during the episode. This pattern has been followed during the past several episodes. An estimated 7.3 million cubic yards (5.6 million cubic meters) of lava spilled across Halemaʻumaʻu. 💨 The eruptive plume rose to about 24,000 ft (7,300 m) above sea level; higher level winds from the south caused tephra to fall north and east of Kaluapele (Kīlauea caldera) at overlooks within Hawaiʻi Volcanoes National Park, as well as on Highway 11 near Nāmakanipaio Campground, Volcano village, Mauna Loa Estates, and Ohia Estates. The National Weather Service issued an ashfall advisory for these areas downwind. ⛔️ The USGS kept the Kīlauea alert level/aviation color code at WATCH/ORANGE throughout the episode because fallout was not extensive and did not last very long. After the episode ended, USGS lowered Kīlauea to ADVISORY/YELLOW reflecting that volcanic activity had decreased significantly but continues to be closely monitored for possible renewed increase. Kīlauea summit region inflation since the end of episode 48 indicates that another fountaining episode is possible; however, more time is needed to collect data to generate the model to forecast episode 49, which will set a another new record for Kīlauea. 📹 Video clips show Kīlauea episode 48 lava fountaining on June 1, 2026. #Kilauea #Lava #Eruption

Here are some other views of Kīlauea summit eruption lava fountaining episode 38 in Halema‘uma‘u crater on the Island of Hawai‘i, and answers to some of your questions about this activity. 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

In case you ever wondered what it would be liked to be engulfed in a lava fountain... This video was recorded by the V3 camera, 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. RIP V3 🪦 V1 ( and V2 ( continue to operate.

And another one! On Wednesday, April 29, at about 12:28 PM MDT, there was another eruption at Black Diamond Pool (in Biscuit Basin, Yellowstone National Park)! This one was larger than Tuesday's event and sent muddy water and steam towards the camera, which sits on a remnant of the boardwalk that was wrecked by the July 23, 2024, explosion from the pool. This is perhaps the largest eruption of the pool since the 2024 explosion and is an important demonstration of hydrothermal hazards in Yellowstone National Park! 📹: This eruption at Black Diamond Pool occurred on Wednesday, April 29, just before 12:28 AM MDT. It is probably the largest such event to have occurred at the pool since the explosion of July 23, 2024.

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

Kīlauea episode 43 of lava fountaining at the summit, within Hawai’i Volcanoes National Park continues at this time. The lava fountain from the south vent has decreased to around 1000 feet (300 meters) high and the lava fountain from the north vent is 700 feet (200 meters) high. Tephra fall to the north and east has greatly reduced in the past hour. Fine ash and Pele’s hair has been reported falling as far as Hilo and Hawaiian Paradise Park. Help support science and community awareness by submitting a tephra fall report at: The National Weather Service has issued an Ashfall Warning for the region around Kīlauea summit and an Ashfall Advisory for the communities to the east. Hawaii County Civil Defense Agency announced the closure of Highway 11 between the 24 and 40 mile markers due to dangerous conditions being created by tephra falling. Hawai’i Volcanoes National Park has announced that temporary closures around Kīlauea summit are in place due to volcanic hazards. Lodging guests of Volcano House and Kilauea Military Camp will be allowed to enter the park. 🎥 Video of episode 43 fountaining and eruptive plume on March 10, 2026.

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. Kīlauea has been erupting episodically since December 23, 2024, from two vents (north and south) in Halema‘uma‘u, in Hawai’i Volcanoes National Park. Lava fountaining episodes, which generally last for less than 12 hours, are separated by pauses that can be longer than three weeks. 🎥 Video of episode 46 on May 5, 2026. #Eruption #Kilauea #Lava

Kīlauea Eruption Update — Episode 46 of Kīlauea summit lava fountaining began at 8:17 a.m. HST today, May 5, and is ongoing. This eruption is taking place within Kīlauea summit caldera in Hawai‘i Volcanoes National Park. Lava fountains at the north vent are currently about 350 feet (100 meters) high. National Weather Service forecasts light and variable winds becoming southeast this morning, which suggests that volcanic gas emissions and volcanic material may be distributed throughout Kīlauea summit region and north/northwest of Halemaʻumaʻu. The National Weather Service Honolulu Forecasting Office has issued an Ashfall Advisory for the southeast and east side of the Island of Hawaiʻi. Fountaining episodes typically last 12 hours of 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 46 at 8:30 a.m. HST on May 5, 2026. #Kilauea #Eruption #Lava

🌪 It’s a Twister! Or Is It? 🤔 Ever spotted a swirling column of ash or tephra near Kīlauea’s lava fountains and thought, “Whoa, a tornado!”? Not quite. These whirlwinds—called puahiohio in ʻŌlelo Hawaiʻi (the Hawaiian language)—are technically dust devils, or more precisely, ash devils, tephra devils, or lava devils, depending on the debris involved. 🔥 How do they form? Intense heat from lava or a recent eruption heats the air at ground surface. This hot air rises into the cooler air above it, spinning and pulling in debris—creating a mini vortex that looks dramatic but isn’t a tornado. ⚠️ Why care? They’re smaller than tornadoes but still pack strong winds and hot debris. Definitely not something you want to walk into! As we close out the whirlwind of a year that 2025 has been (37 lava fountaining episodes, 39 if you count the two in 2024!), the puahiohio are another reminder of the dynamic nature of Kīlauea. #Kilauea #twister #puahiohio 🎥Video captured by the V1cam shows a puahiohio near Kīlauea's active vents in Halemaʻumaʻu on December 9, 2025, following episode 38 lava fountaining on December 6.
