Cascades Volcano Observatory update for Friday, June 5, 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, Mount Hood, Newberry, and Mount St. Helens. Field staff performed station maintenance at Mount Hood and Mount Rainier. In this exclusive footage, we observe USGS volcano scientists in their natural habitat. Clad in their distinctive orange flight suits, the scientists cautiously traverse the steaming lava dome of Mount St. Helens, formed during the volcano's remarkable 1980–1986 dome-building period. Despite the rugged terrain, they appear completely at ease, stopping periodically to inspect rocks, collect samples, and point enthusiastically at things invisible to the untrained eye. The bright orange plumage serves two purposes: visibility in the field and easy identification by helicopters. Their diet consists primarily of coffee, trail mix, and curiosity. The lava dome, still warm and steaming in places, provides an ideal environment for the volcano scientist. Notice how the two work together. This behavior helps maximize productivity while also maintaining a high level of safety and situational awareness. Remarkable. The expedition concludes with successfully maintained monitoring equipment, valuable observations, and dozens of photos that all look identical to everyone else. Nature is truly amazing. 📹: USGS field engineers can be seen maintaining a monitoring station on the 1980-1986 lava dome inside the crater of Mount St. Helens. Photo Credit: USGS

Kīlauea Eruption Update — Episode 48 of Kīlauea summit lava fountaining began at 4:40 a.m. HST today, June 1, and is ongoing. This eruption is taking place within Kīlauea summit caldera in Hawai‘i Volcanoes National Park. Precursory lava flows began from the south vent at 5:41 p.m. on May 30 and continued intermittently. Currently, only the north vent is erupting a lava fountain that is reaching 650 feet (200 meters) high. National Weather Service has issued an ashfall advisory for the areas to the southwest and northeast of Halemaʻumaʻu. 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 48 on June 1. 2026. #Kilauea #Eruption #Lava

🌋Kīlauea eruption episode 47 summary Episode 47 of the Kīlauea summit eruption in Hawai‘i Volcanoes National Park stopped at 12:27 am HST May 15 after 9 hours of lava fountaining. 🌋 Lava flowed from the south vent about 75 times in the 12 hours before episode 47, but only the north vent produced a lava fountain (up to 650 ft/200 m) during the episode. The south vent continued to overflow for a couple of hours, diminishing over time to spattering and then only flames. An estimated 6.2 million cubic yards (5.2 million cubic meters) of lava spilled across Halemaʻumaʻu, covering nearly half of the crater floor with new lava. 💨 The eruptive plume rose to about 20,000 ft (6,000 m) above sea level; weak winds as the episode peaked allowed the plume to rise vertically, causing tephra to fall around Kaluapele (Kīlauea caldera). Most tephra fell within the closed area of Hawaiʻi Volcanoes National Park, but sparse reticulite up to 3 inches (5 centimeters) in size fell at both the Uēkahuna and Keanakākoʻi overlooks. Fine ash and Peleʻs hair fell in communities to the northeast. ⛔️ 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 47 indicates that another fountaining episode is possible; however, more time is needed to collect data to generate the model to forecast episode 48. 📹 Video clips show Kīlauea episode 47 lava fountaining on May 14, 2026. #Kilauea #Lava #Eruption

Kīlauea Eruption Update — Episode 47 of Kīlauea summit lava fountaining began at 3:27 p.m. HST today, May 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 south vent at 2:57 a.m. this morning, May 14, and continued intermittently today from both the north and south vents. Both vents are currently erupting, with low-level activity in the south vent while lava fountains at the north vent are currently about 65 feet (20 meters) high. National Weather Service forecasts low-level tradewinds today, which suggests that volcanic gas emissions and volcanic material may be distributed southwest of Halemaʻumaʻu. Fountaining episodes typically last 12 hours of less, but ash can remain in the air for longer depending on wind and weather conditions.

Kīlauea Eruption Episode 46 Update May 5, 2026, 5:30 pm HST Episode 46 of lava fountaining in Halemaʻumaʻu at the summit of Kīlauea began at 8:17 am HST on May 5 and ended about 9 hours later at 5:22 pm HST. With the reduced ground and aviation hazards due to the lava fountaining episode ending, the USGS is dropping the Volcano Alert Level from WATCH to ADVISORY and the Aviation Color Code from ORANGE to YELLOW. We’ll share more details about this eruptive episode in our next post. 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. #Kilauea #tephra #lava

❄️ Snow at the summit of Mauna Loa, Earth's largest active volcano, today. Much of Hawaii remains under a flood watch today, January 5, but that rain falls as snow at the high-altitude summit of Mauna Loa (13,678 feet or 4,169 meters above sea level). Several USGS cameras captured these views from different locations around Mokuʻāweoweo, the summit caldera of Mauna Loa.

Inclined lava fountaining continues as of 5:30 p.m. on August 22 during episode 31 of Kīlauea’s summit eruption. Lava fountains from the north vent are extending about 300 meters (1000 feet) laterally, going eastward towards the center of Halemaʻumaʻu crater. Parts of Halemaʻumaʻu crater floor are being blanketed with tephra or covered with lava flows. The south vent is also erupting, with lower-level activity. Inclined lava fountains have been observed before on Kīlauea, in both the Kīlauea Iki (1959) and Maunaulu eruptions (1969) that featured similar episodes of lava fountaining. In both previous cases, the inclined fountains were caused by temporary obstructions within the eruptive vents, usually collapse of part of the vent or surrounding cone. Today’s incline could be caused by construction of an inner cone during the precursory activity before the start of the episode. It’s similar to if you’ve ever put your thumb over a garden hose, causing the water to spray out of the hose at an angle. #usgs #HVO #Kilauea #lava

🌋Volcano monitoring at the USGS Hawaiian Volcano Observatory (HVO) is a family affair. Even in their homes, #HVO staff closely watch the 24/7 livestream cameras, along with multiple other data streams, including gas, tilt, and seismic sensors. Sometimes, they have the help of a dedicated pet. Here “The Colonel” communicates that spattering is occurring in the north vent. His human geologist recorded the observation and relayed the message on. Indeed, glow was observed overnight in both the north and south vents in Halemaʻumaʻu crater, and spatter was intermittently visible in the north vent. This morning, HVO geologists in the field at the summit of Kīlauea volcano observed two small lava ponds in the north vent, as well as spattering in the south vent. The first overflow from the north vent happened at 12:52 p.m. HST today, December 5. Magma is standing high in the eruptive conduits, and ground deformation models indicate that episode 38 fountains are likely to begin between December 6 and 8. You (and your pets) can watch along on the three USGS Youtube Kīlauea livestream cameras:

Eruptive activity at the summit of Kīlauea volcano on the Island of Hawaiʻi remains paused as of December 2. However, USGS Hawaiian Volcano Observatory geologists on a monitoring overflight this morning observed a spattering lava surface deep in both the north and south vents in Halemaʻumaʻu crater. Glow was visible in both vents in webcam imagery last night, as well as weak spattering within the north vent. Based on patterns of ground inflation since the end of episode 37 on November 25, models show that another lava fountaining episode is likely between December 5 and 9. This eruptive activity is confined to the summit of Kīlauea volcano, within Hawaiʻi Volcanoes National Park. #Kilauea #lava

Episode 31 of the ongoing Kīlauea summit eruption just started today, August 22, at 2:04 p.m. Hawaii Standard Time. Spattering within the north vent was visible overnight, along with several sluggish overflows. The summit region switched from inflationary deformation to deflation with the start of the fountaining. So far, eruptive activity has been localized to the north vent only during this episode. During episode 30, both the north and south vents erupted, as well as a new fissure in the south caldera wall. Watch along as episode 31 unfolds on the three USGS Hawaiian Volcano Observatory’s livestream cameras: V1cam: V2cam: V3cam: Please see the Hawaiʻi Volcanoes National Park website for visitor information:

🌋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.

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

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 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.
