The Kamchatka branch of the Russian Academy of Sciences' Geophysical Service said satellite data showed the ash cloud rising to approximately 12,000 metres above sea level between 07:17 a.m. and 07:32 a.m. local time, The Caspian Post reports, citing TASS. Shiveluch is one of the most active volcanoes on the Kamchatka Peninsula. The volcanic complex consists of the ancient Old Shiveluch volcano, an old caldera and the active Young Shiveluch volcano, and is estimated to be between 60,000 and 70,000 years old. The volcano is located about 50 kilometres from the village of Klyuchi in the Ust-Kamchatsky District and around 450 kilometres from the regional capital, Petropavlovsk-Kamchatsky. https://www.sott.net/article/507512-Russias-Shiveluch-volcano-erupts-sends-ash-12-km-high Mon, 20 Jul 2026 13:22:20 +0000 https://www.sott.net/article/507415-Phivolcs-records-effusive-eruption-at-Mayon-Volcano-Philippines The Philippines' Mayon volcano continued spewing lava and rocks in the early hours of Tuesday, the Philippine Institute of Volcanology and Seismology (Phivolcs) said. The agency said the eruption has persisted for 190 consecutive days, producing lava flows, pyroclastic density currents and rockfalls. A Level 3 alert remains in effect, which bars entry into the 6-kilometer Permanent Danger Zone. Phivolcs said the alert, in place since January 2026, indicates heightened volcanic unrest with magma close to the crater. Authorities in Albay province continue enforcing the danger zone, while PHIVOLCS said it is monitoring the volcano around the clock.

KVERT reported that the approximately 3-minute event generated an ash plume up to 3.5 km (11 500 feet) above sea level, extending about 10 km (6 miles) west of the volcano. Tokyo VAAC issued a Volcanic Ash Advisory for a reported eruption to approximately 5.2 km (17 000 feet) above sea level. However, ash was not identifiable in Himawari-9 satellite imagery at 21:40 UTC, and the agency said it would issue a further advisory only if ash was detected. Volcanologists at the Kamchatka Volcanic Eruption Response Team (KVERT) raised the Aviation Color Code from Green to Orange and said the eruption lasted about 3 minutes. There were no further ash explosions observed, and activity at the volcano continued in the form of gas-and-steam emissions.

The eruption sent a towering column of ash and volcanic gases high above the summit before part of the eruptive material collapsed, producing a fast-moving pyroclastic flow that raced down Semeru's flanks through established drainage channels. Pyroclastic flows are among the most dangerous volcanic hazards on Earth. They consist of a dense mixture of superheated gas, volcanic ash, and rock fragments that can travel at speeds exceeding 100 km/h (60 mph) while reaching temperatures of several hundred degrees Celsius. Located in East Java, Indonesia, Semeru is the highest volcano on the island of Java and one of Indonesia's most active volcanoes.

Indonesian authorities have raised alert levels as three active volcanoes, including Dukono, Ibu in North Maluku, and Lewotobi Laki-laki in East Nusa Tenggara, erupted simultaneously, sending ash columns 400 - 500 metres above their summits. According to Lana Saria, acting head of the Geological Agency under Indonesia's Ministry of Energy and Mineral Resources, the three volcanoes are among the country's most active. Lewotobi Laki-laki is the site of a major eruption in November 2024 that killed at least nine people, damaged more than 2,300 homes and forced around 16,000 residents to evacuate. Dukono and Ibu, meanwhile, have experienced near-continuous volcanic activity for years, regularly releasing ash into the atmosphere and remaining under heightened monitoring. https://www.sott.net/article/506846-Indonesia-raises-alert-levels-as-3-volcanoes-erupt-simultaneously Fri, 12 Jun 2026 14:37:56 +0000 https://www.sott.net/article/506806-Indonesias-Mount-Lewotobi-Laki-laki-erupts-again-residents-warned Mount Lewotobi Laki-laki in Indonesia's East Nusa Tenggara province erupted again on Wednesday afternoon, prompting authorities to reiterate safety warnings for residents and visitors near the volcano. According to Indonesia's Center for Volcanology and Geological Hazard Mitigation (PVMBG), the eruption occurred at 13:46 local time (WITA) on June 10. The volcanic ash column rose approximately 800 meters above the crater, reaching an altitude of 2,384 meters above sea level, News.az reports, citing ABC News. Officials reported that thick gray ash drifted westward and northwestward, while eruptive activity was still ongoing at the time of reporting. https://www.sott.net/article/506806-Indonesias-Mount-Lewotobi-Laki-laki-erupts-again-residents-warned Wed, 10 Jun 2026 14:12:27 +0000 https://www.sott.net/article/506746-Sakurajima-volcano-eruption-in-Japan-massive-ashfall Sakurajima Volcano unleashed one of its most intense eruptions on June 7, 2026, sending a towering plume of volcanic ash across Kagoshima City. 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.

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.

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 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 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).
