What started as a clear June morning turned into a blanket of gray chaos within hours—visibility dropped to dangerous levels, ash coated streets, vehicles, and rooftops, and thousands of tourists found their summer vacation plans upended. The eruption was no minor event. Japan Meteorological Agency (JMA) immediately raised alert levels, classifying it as high-intensity with ash plumes reaching kilometers into the sky. Residents and tourists received urgent warnings: stay indoors, wear masks, avoid all non-essential travel. The timing couldn't have been worse. Summer tourism season was in full swing, and travelers from across the globe were converging on Kagoshima to experience one of Japan's most dramatic natural attractions. https://www.sott.net/article/506746-Sakurajima-volcano-eruption-in-Japan-massive-ashfall Sun, 07 Jun 2026 11:54:06 +0000 https://www.sott.net/article/506743-Shiveluch-Volcano-eruption-triggers-highest-aviation-alert-over-Russias-far-east-ash-plume-10-kilometers-high The eruption of the Shiveluch volcano on the Kamchatka Peninsula in Russia's Far East has sent a massive plume of ash 10 kilometers into the sky and triggered red-level aviation alerts for the area and nearby regions. The ash cloud from Saturday's eruption stretched some 50 kilometers from the volcano as it traveled east toward the Bering Sea, according to the Volcanology and Seismology Institute of the Far Eastern Branch of the Russian Academy of Sciences. A more powerful explosion that could send ash up to 12 kilometers into the sky "could occur at any time," the institute warned. A video recorded by scientists and published on social media showed a massive plume of grey smoke and ash rising high into the sky above the volcano. https://www.sott.net/article/506743-Shiveluch-Volcano-eruption-triggers-highest-aviation-alert-over-Russias-far-east-ash-plume-10-kilometers-high Sun, 07 Jun 2026 10:42:00 +0000 https://www.sott.net/article/506724-Indonesias-Mount-Lewotobi-Laki-Laki-erupts-forcing-airport-to-close A highly active volcano in eastern Indonesia erupted several times on Friday (Jun 5), spewing towering ash columns into the sky and forcing a local airport to close, authorities said. Mount Lewotobi Laki-Laki on Flores Island erupted at 11.15am, sending volcanic material 2.5km into the air, the national volcanology agency said in a statement. It came after several other eruptions earlier on Friday. Lewotobi Laki-Laki falls under Indonesia's second-highest alert level for volcanic activity, with a 5km exclusion zone in force around its crater. https://www.sott.net/article/506724-Indonesias-Mount-Lewotobi-Laki-Laki-erupts-forcing-airport-to-close Sat, 06 Jun 2026 13:16:17 +0000 https://www.sott.net/article/506666-Hawaiis-Kilauea-volcano-begins-48th-episode Hawaii's Kilauea volcano experienced its latest eruption episode Monday. On Monday, June 1, at 4:40 a.m., Episode 48 of the ongoing Halemaʻumaʻu eruption at the summit of Kilauea began. The north vent is particularly active this episode, with occasional overflows from the south vent, according to the Hawaiian Volcano Observatory. Around 6:30 a.m., officials observed fountaining over 500 to 650 feet above the north vent. The plume from this eruption is currently reaching 24,000 feet above sea level. The National Weather Service said tephra, which is material that emerges from a volcano during an eruption, could be dispersed to the north based on the winds from the south at 10,000 to 20,000 feet above sea level. https://www.sott.net/article/506666-Hawaiis-Kilauea-volcano-begins-48th-episode Tue, 02 Jun 2026 14:42:55 +0000 https://www.sott.net/article/506612-Mount-Marapi-eruption-ejects-column-of-ash-2000-meters-high-in-West-Sumatra-Indonesia The Geological Agency of the Ministry of Energy and Mineral Resources (ESDM) reported that Mount Marapi in West Sumatra Province had erupted by launching a volcanic ash column of approximately 2,000 meters above the peak. The Acting Head of the Geological Agency, Lana Saria, in his statement in Jakarta, Saturday, said that the volcanic activity of the volcano with a height of around 4,891 meters above sea level was recorded at 08.42 WIB this morning. "The observed ash column is gray with a thick intensity leaning towards the northeast. This eruption was recorded on the seismogram with a maximum amplitude of 30 mm and a temporary duration of one minute 25 seconds," he said. https://www.sott.net/article/506612-Mount-Marapi-eruption-ejects-column-of-ash-2000-meters-high-in-West-Sumatra-Indonesia Sat, 30 May 2026 15:47:44 +0000 https://www.sott.net/article/506610-New-geyser-is-disrupting-life-in-a-small-community-in-Michoacan-Mexico A suspected geyser that burst from the pig pens and backyard of a small Mexican farm this week has prompted evacuations, a school closure and a multi-agency scientific response, according to state and federal officials. The hydrothermal eruption began overnight Monday in the rural community of El Salitre, about 135 kilometers west of Morelia, the capital of the west-central state of Michoacán. Water, mud and gases began spewing from "the middle of pig pens on a small family farm," according to authorities. As of late Wednesday morning, the geyser-like phenomenon was still active, though in a reduced, bubbling-mud state with constant gas emissions rather than a jet, according to Mi Morelia. Earlier, authorities had reported an initial spout of about 15 meters, which subsided to eight meters. An unknown number of pigs "died as the result of the eruption," according to N+, the news division of TelevisaUnivision. https://www.sott.net/article/506610-New-geyser-is-disrupting-life-in-a-small-community-in-Michoacan-Mexico Sat, 30 May 2026 14:19:00 +0000 https://www.sott.net/article/506585-Popocatepetl-volcano-erupts-explosively-in-Mexico This Thursday, May 28, the Popocatépetl volcano once again drew the attention of much of the country , as monitoring cameras captured the exact moment when Don Goyo had an explosive eruption that generated a column of smoke and gases kilometers long during the afternoon of this day. It was through the different social media platforms that images of the enormous plume of smoke that came out of the crater of one of the most important volcanoes in the Mexican Republic began to be shared. Video of the eruption of the Popocatépetl volcano on May 28th As can be seen in the images shared on different social media accounts, the fumarole of the Popocatépetl volcano after the explosive eruption carried gases and columns of smoke towards the southeast area of ​​Don Goyo. The images that were shared clearly show the exact moment the explosion occurred , which left one of the most shocking images of the week in the central region of the Mexican Republic .

Phivolcs said its Ligñon Hill IP Camera in Legazpi City captured the meteor at around 10:33 p.m., but noted that it disintegrated while still in the atmosphere and did not reach the slopes of Mayon. At the time of the sighting, the active volcano in Albay was on its 140th consecutive day of effusive eruption, marked by the slow outflow of lava and intermittent pyroclastic density currents. Earlier in the evening, the volcano generated lava collapse-fed pyroclastic density currents (PDCs), or "uson," along the Mi-isi and Basud gullies, as well as minor strombolian activity, which refers to short explosive bursts that eject glowing volcanic material and produce brief lava fountains. https://www.sott.net/article/506520-Meteor-fireball-seen-over-erupting-Mayon-Volcano-in-the-Philippines-on-May-25 Mon, 25 May 2026 18:41:24 +0000 https://www.sott.net/article/506494-Ice-core-discovery-finds-volcanic-eruptions-could-cause-greater-global-disruption-than-previously-thought New research from the University of St Andrews has precisely dated an eruption from Newberry Volcano and discovered that its ash spread more than 5,000 km across the globe, far further than previously thought for an eruption of its size. Published in Quaternary Science Reviews, researchers identified ash particles from the Newberry Pumice eruption of Newberry Volcano (Oregon, U.S.) in a Greenland ice core by geochemical fingerprinting — matching the chemical elements in the far-flung ash particles to volcanic deposits of the Newberry Pumice ash from its most recent "Big Obsidian" eruptive period. Previous dates had narrowed the timing of the eruption to an approximate 140-year window around the turn of the 7th Century AD. Finding the ash in the ice allowed researchers to pinpoint the timing of the Newberry Pumice eruption to within two years of 686 AD, due to the very precise age models that have been developed for Greenland ice cores. https://www.sott.net/article/506494-Ice-core-discovery-finds-volcanic-eruptions-could-cause-greater-global-disruption-than-previously-thought Sat, 23 May 2026 19:50:41 +0000 https://www.sott.net/article/506483-Shallow-magnitude-6-0-earthquake-on-Hawaii-island-shakes-the-state-no-tsunami-generated No tsunami is expected following a magnitude 6.0 earthquake that occurred about seven miles to the east-southeast of Honaunau in the South Kona area of Hawaii Island. According to the U.S. Geological Survey, the earthquake occurred at 9:46 p.m. It was centered about 3.7 miles east-southeast of the Honaunau-Napoopoo area along the western flank of Mauna Loa, at a depth of 14 miles. The Pacific Tsunami Warning Center said no tsunami was generated by the earthquake. A second, weaker magnitude 3.2 earthquake occurred six minutes later, just to the northwest of the first about 13 miles beneath the surface. https://www.sott.net/article/506483-Shallow-magnitude-6-0-earthquake-on-Hawaii-island-shakes-the-state-no-tsunami-generated Sat, 23 May 2026 09:48:59 +0000 https://www.sott.net/article/506450-Major-Italian-volcano-speeds-toward-transition-major-eruption-could-be-on-the-way-The-system-is-likely-to-reach-a-breaking-point Campi Flegrei, a volcanic caldera west of Naples, is speeding toward a transition within the next decade, a new study suggests, but researchers can't yet say whether that transition will be an eruption or some other change in the volcano's internal plumbing. The caldera, also known as the Phlegraean Fields, is home to about 500,000 people who would be at risk in the event of an eruption. The caldera stretches about 9 miles (15 kilometers) in diameter and formed in a massive eruption 40,000 years ago. Other, smaller eruptions have happened since, including an explosive one in 1528 that built Monte Nuovo, a 433-foot (132 meters) cinder cone. "Our paper identifies when the system is likely to reach a breaking point, but it cannot determine what will happen at that breaking point with the current data," said study first author Davide Zaccagnino, a postdoctoral researcher who studies geological hazards at the Southern University of Science and Technology in Guangdong, China. https://www.sott.net/article/506450-Major-Italian-volcano-speeds-toward-transition-major-eruption-could-be-on-the-way-The-system-is-likely-to-reach-a-breaking-point Thu, 21 May 2026 20:00:26 +0000 https://www.sott.net/article/506422-Ash-from-Bezymianny-volcano-eruption-covers-2-villages-in-Kamchatka-Russia-ash-column-of-up-to-10-km-high In the Ust-Kamchatsky district in the village of Mayskoye and the settlement of Kozyrevsk fell out Ash from the eruption of Bezymyanny volcano. Ash column burst out to a height of up to 10 km with the volcano's height being 3020 meters. Volcanologists have assigned the volcano a "red" hazard rating, meaning it poses a hazard to air travel. Emergency services have not received any complaints or calls from residents. There was minor ash fall in Kozyrevsk, and about 3 mm in Maysky. Volcanic ash is dangerous to humans. Emergency workers recommend staying indoors and closing windows and doors whenever possible. Inhaling ash can cause allergic reactions, so wear respirators and headbands soaked in a soda solution. It's best to cover equipment with plastic and avoid using it until the ashfall subsides. Bringing ash into your home, including on your clothing, is not recommended. When cleaning ash from your home, wear a mask and goggles.

Papua New Guinea authorities have warned of falling pumice, ash, unpredictable swells and turbulent currents in the area near the eruption of the provisionally-named Titan Ridge Volcano. Satellites have captured the event unfold from space, while seafarers in the area have seen it unfold. One fisherman, Kennedy Masis, was searching for tuna when he "saw smoke coming out of the sea", he told the ABC. "Twelve years as a fisherman I've never seen anything like that ... it's scary. "It sounds like thunder and the sea smells like metal burning." He said the next day he saw plenty of dead fish near the reef which was like a "boiling spring". https://www.sott.net/article/506400-Undersea-volcano-erupts-in-Papua-New-Guineas-Bismarck-Sea-prompting-tsunami-concerns Tue, 19 May 2026 11:35:47 +0000 https://www.sott.net/article/506396-WHO-in-panic-mode-as-World-Health-Assembly-kicks-off Today is first day of the World Health Organization's 79th annual World Health Assembly, where delegates come together to set policies and priorities for global health.

Footage shows the volcano releasing a towering ash column over Kagoshima Prefecture on the southern island of Kyushu on May 8. Authorities confirmed the blast occurred at 4:15 pm local time from the summit crater of Minamidake. The eruption triggered a volcanic ash advisory issued by the Tokyo Volcanic Ash Advisory Centre (VAAC), with ash drifting towards the southeast. Sakurajima is one of Japan's most active volcanoes, with a history of frequent eruptions. Originally an island, it became a peninsula after a significant eruption in 1914. Japan lies inside the Pacific 'Ring of Fire' where the majority of Earth's volcanic eruptions and earthquakes happen. https://www.sott.net/article/506199-Sakurajima-volcano-eruption-sends-11500ft-ash-plume-into-the-sky-in-Japan-on-May-8 Sat, 09 May 2026 14:11:51 +0000 https://www.sott.net/article/506183-3-dead-after-Mount-Dukono-volcano-erupts-on-Indonesian-island-ash-column-6-miles-high Three people hiking on Indonesia's Mount Dukono have died after the volcano erupted on Friday morning. Videos and pictures of the eruption show the volcano, located on North Maluku island, spewing a column of ash stretching 10km (six miles) into the sky. The three victims were part of a group of 20 Singaporeans and Indonesians hiking on the mountain despite restrictions. The rest of the group was eventually located by rescuers and evacuated from the mountain. The volcano has erupted more than 200 times since last March. Officials had previously issued warnings against climbing the mountain due to safety concerns. The latest eruption took place at 07:41 local time (22:41 GMT Thursday), when there were several people on the mountain on early morning hikes. https://www.sott.net/article/506183-3-dead-after-Mount-Dukono-volcano-erupts-on-Indonesian-island-ash-column-6-miles-high Fri, 08 May 2026 17:52:58 +0000 https://www.sott.net/article/506056-Philippines-Mayon-Volcano-erupts-unleashes-fast-moving-pyroclastic-flow-disrupts-traffic-prompts-warnings-from-authorities Mayon Volcano erupted late on Saturday afternoon, unleashing a fast-moving pyroclastic flow and thick ash plume that disrupted traffic and prompted warnings from authorities. The event involved a pyroclastic density current, locally known as "uson," which surged down the volcano's slopes. Camera footage shows lava flow collapse-fed pyroclastic density current at the southwestern slopes of Mayon Volcano at 5:38 pm, as captured by the The Philippine Institute of Volcanology and Seismology (Phivolcs). https://www.sott.net/article/506056-Philippines-Mayon-Volcano-erupts-unleashes-fast-moving-pyroclastic-flow-disrupts-traffic-prompts-warnings-from-authorities Sat, 02 May 2026 13:33:25 +0000 https://www.sott.net/article/505873-Tourists-scramble-as-Santiaguito-volcano-erupts-in-Guatemala A group of hikers were forced to flee on April 20 from the top of Santiaguito Volcano when it erupted.

How can magma buried 5, 10, or even 15 km underground be detected without any surface indicators? The answer lies in ambient noise tomography, a technique that analyses natural ground vibrations with high precision. A team from the University of Geneva (UNIGE), the Institute of Geosciences and Earth Resources (CNR-IGG), and the National Institute of Geophysics and Volcanology (INGV) has identified a vast reservoir containing approximately 6,000 km3 of magma beneath Tuscany. Beyond its scientific significance, this breakthrough paves the way for faster and more cost-effective exploration methods to locate resources such as geothermal reservoirs, lithium, and rare earth elements, whose formation is closely linked to deep magmatic systems.

The 44th episode began in the late morning on Thursday, with lava fountains reaching 800 feet, according to the USGS. Video footage from the USGS shows the south Halemaʻumaʻu crater gushing large lava fountains from the ground. As the crater continues to shoot lava, strengthening over time, the risk of tephra falling from volcanic ash clouds and Pele's Hair increases. Tephra is a catch-all term that describes various kinds of rocks blasted into the air during eruptions. https://www.sott.net/article/505656-Hawaii-Gushing-lava-fountains-from-Mount-Kilauea-Volcano-amid-44th-eruption Fri, 10 Apr 2026 14:38:00 +0000 https://www.sott.net/article/505616-Mount-Semeru-volcano-erupts-again-in-Indonesia Mount Semeru, located in Indonesia's East Java province, erupted again on Tuesday (April 7), spewing a massive hot cloud into the sky, according to the Centre for Volcanology and Geological Hazard Mitigation, reported Xinhua. The volcano remains under a Level III alert, the second-highest in the country's four-tier warning system. The eruption at 5.30 pm local time produced an ash column reaching approximately 2,000 metres above the crater, with a thick gray plume drifting north-east and east. Seismographs recorded the event as lasting more than seven minutes. No casualties or immediate damage were reported, but authorities warned that the accumulation of volcanic material on the slopes could trigger debris flows, or lahars, if heavy rainfall occurs. This follows a restless Monday during which the volcano recorded several separate eruptions.

The searing avalanche of ash, gas, and volcanic debris sweeps rapidly down the mountain, showing the immense destructive power of one of Indonesia's most active volcanoes. Pyroclastic flows are among the most dangerous volcanic hazards on Earth. They can move at extremely high speeds and carry scorching material capable of devastating everything in their path. When Semeru produces large collapses like this, the flows often race down drainages on the volcano's flanks and can travel great distances from the summit. Also known as Mahameru, Semeru is the highest volcano on Java and has remained one of Indonesia's most closely watched active volcanoes. This video captures a powerful and dangerous moment as a major pyroclastic flow surges from the volcano during the morning hours. https://www.sott.net/article/505254-Massive-pyroclastic-flow-reaches-the-base-of-Semeru-Volcano-Indonesia Fri, 20 Mar 2026 22:49:49 +0000 https://www.sott.net/article/505194-Lava-flows-reach-ocean-on-Reunion-island-for-first-time-in-nearly-two-decades Lava from the Piton de la Fournaise volcano has reached the ocean on France's Réunion island for the first time in nearly two decades, drawing residents and tourists. https://www.sott.net/article/505194-Lava-flows-reach-ocean-on-Reunion-island-for-first-time-in-nearly-two-decades Wed, 18 Mar 2026 10:00:59 +0000 https://www.sott.net/article/505165-5-kilometer-high-eruption-column-at-Kanlaon-Volcano-in-the-Philippines Kanlaon Volcano in Negros Island had an moderate explosive eruption on Sunday evening, its third this year, the Philippine Institute of Seismology and Volcanology (Phivolcs) said. According to Phivolcs in a statement, the eruption occurred at the summit of the volcano at exactly 06:07 p.m. The eruption generated a 5 kilometer-high eruption column that drifted to the southeast and northeast. "This is the third event at Kanlaon this year, following similar eruptions in 19 and 26 February 2026," Phivolcs said. Meanwhile, Alert Level 2 remains raised over Kanlaon Volcano with prohibited entry into its 4 kilometer Permanent Danger Zone. Under Alert Level 2, sudden steam-driven (phreatic) eruptions and signs of impending magmatic activity are possible. https://www.sott.net/article/505165-5-kilometer-high-eruption-column-at-Kanlaon-Volcano-in-the-Philippines Mon, 16 Mar 2026 14:17:44 +0000 https://www.sott.net/article/505177-Mount-Merapi-in-Central-Java-Indonesia-erupts-sends-pyroclastic-flows-up-to-1-6-km-southwest Mount Merapi, straddling Indonesia's Yogyakarta and Central Java Provinces, produced two pyroclastic flows early Monday, traveling a maximum of 1.6 kilometers toward the southwest, officials said.

According to official reports from INSIVUMEH, the volcano continues to produce frequent explosive eruptions throughout the day. Visual observations and seismic monitoring indicate that approximately 5 to 15 explosions are occurring every hour. These eruptions are generating thick columns of volcanic ash rising as high as 4,500 to 5,000 meters above sea level. The ash plume can be seen clearly from surrounding areas, forming large gray clouds drifting with the wind. In addition to ash emissions, glowing volcanic material is being ejected from the summit crater. At night, incandescent lava fragments can be seen illuminating the upper slopes of the volcano. These hot materials can fall onto the volcano's flanks and may trigger avalanches of volcanic debris, posing a serious hazard to nearby areas. https://www.sott.net/article/504917-Mount-Fuego-volcano-erupts-violently-in-Guatemala-Ash-rises-5000-meters Sun, 01 Mar 2026 12:02:10 +0000 https://www.sott.net/article/504880-Philippines-Kanlaon-volcano-makes-explosive-eruption-shoots-ash-plume-2500-metres-above-the-crater The Philippines' Kanlaon Volcano made an explosive eruption at around 7:04pm on Thursday, Feb. 26, 2026 The explosive eruption of the volcano, located on Negros Island in the central Philippines, lasted approximately two minutes, as recorded by seismic and infrasound instruments, according to the latest update from the Philippine Institute of Volcanology and Seismology (PHIVOLCS). The eruption generated a dense ash plume rising about 2,500 meters above the summit crater, which then drifted southwest. Incandescent ballistic fragments rained around the crater, while pyroclastic density currents (PDCs) descended the eastern and southeastern upper slopes, reaching up to 2 kilometers from the summit. https://www.sott.net/article/504880-Philippines-Kanlaon-volcano-makes-explosive-eruption-shoots-ash-plume-2500-metres-above-the-crater Fri, 27 Feb 2026 15:02:42 +0000 https://www.sott.net/article/504856-Mud-volcano-erupts-near-homes-in-Colombia-evacuations-underway A mud volcano has erupted in northwest Colombia, and authorities have ordered precautionary evacuations nearby, according to officials.

With no signs of slowing down, the bump that's roughly 19 miles across may cause some worry that the iconic locale's hibernating supervolcano is readying for an apocalyptic reawakening. Although impressed by the situation, the Yellowstone Volcano Observatory's scientist-in-charge doesn't sound particularly worried. "I think it's pretty stunning even if it's not particularly unusual," Mike Poland recently explained to Cowboy State Daily. This particular example of uplift or deformation is occurring at the northern rim of Yellowstone Caldera in northwest Wyoming. However, it's far from the first time researchers documented the geological occurrence. The most recent instance spanned around 16 years before wrapping up in 2020. In 1996, yet another deformation took place over four years.
