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 study was published in the journal Communications Earth & Environment.

The broadcaster NTV cited the Kagoshima Local Meteorological Observatory as saying the plume reached over 3,000 meters into the sky. It was the active volcano's first eruption since December. https://www.sott.net/article/505675-Japan-Sakurajima-Volcano-sends-impressive-ash-plume-3000-meters-high-into-sky Sat, 11 Apr 2026 18:53:38 +0000 https://www.sott.net/article/505656-Hawaii-Gushing-lava-fountains-from-Mount-Kilauea-Volcano-amid-44th-eruption Kīlauea volcano erupted for the 44th time since Dec. 23, 2024, producing large lava fountains in Hawaii on Thursday. 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.

According to observations from the Kamchatka Volcanic Eruption Response Team (KVERT) and satellite data, the eruption lasted about 30 minutes and produced a dense ash column that rose rapidly above the summit. The Tokyo Volcanic Ash Advisory Centre confirmed the plume height, News.Az reports, citing The Watchers. KVERT raised the Aviation Color Code to Red at 02:52 UTC, indicating an immediate and significant threat to aircraft. The ash cloud drifted eastward from the volcano, extending roughly 10 km (6 miles) from the summit. https://www.sott.net/article/505434-Russia-Sheveluch-volcano-eruption-sends-ash-11-km-aviation-red-alert Mon, 30 Mar 2026 13:45:17 +0000 https://www.sott.net/article/505264-Kanlaon-Volcano-in-the-Philippines-erupts-all-morning-continuous-ash-plumes-for-hours-Mar-21-2026 This timelapse video shows ash emissions from Kanlaon Volcano recorded on the morning of March 21, 2026, using monitoring cameras in Canlaon City and Mansalanao, La Castellana. According to the Philippine Institute of Volcanology and Seismology (PHIVOLCS), ash emission activity occurred from 5:58 AM to 9:02 AM local time, producing ash plumes rising up to 500 meters above the summit and drifting toward the south and southwest. This activity follows a series of four ash emission episodes that began at 9:02 PM the previous evening, with individual events lasting between 43 and 184 minutes. Kanlaon remains under Alert Level 2, indicating moderate unrest and the potential for further sudden explosive activity. Authorities strictly prohibit entry into the 4-kilometer Permanent Danger Zone (PDZ) due to hazards such as ashfall, ballistic fragments, rockfalls, and pyroclastic density currents.

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. Agus Budi Santoso, head of the Yogyakarta Geological Disaster Technology Research and Development Center (BPPTKG), said flows descended toward the Kali Krasak (Krasak River) between midnight and 6 a.m. local time. "Two pyroclastic flows were observed toward the southwest (Kali Krasak) with a maximum run of 1,600 meters," Agus said in a statement Monday in Yogyakarta. The flows had amplitudes of 18-33 mm and durations of 175-188 seconds, according to BPPTKG observations. https://www.sott.net/article/505177-Mount-Merapi-in-Central-Java-Indonesia-erupts-sends-pyroclastic-flows-up-to-1-6-km-southwest Mon, 16 Mar 2026 14:17:14 +0000 https://www.sott.net/article/505122-Shiveluch-volcano-Kamchatka-eruption-with-huge-ash-cloud-up-to-27000-ft-altitude On 11 March, the volcano showed dramatic activity. A strong eruption generated a dense grey ash plume, which reached approx. 27,000 ft (8,200 m) altitude and drifted to the east. This is highly likely might mean that the ongoing growing lava dome has been destroyed. https://www.sott.net/article/505122-Shiveluch-volcano-Kamchatka-eruption-with-huge-ash-cloud-up-to-27000-ft-altitude Thu, 12 Mar 2026 20:44:51 +0000 https://www.sott.net/article/505105-Indonesias-Mount-Marapi-erupts-spewing-ash-up-to-1-mile Indonesia's most active volcano, Mount Marapi, erupted Monday, sending thick gray ash 1.6 kilometers (nearly a mile) above its peak, state media reported. The early morning eruption of Marapi, located in West Sumatra province, was recorded on a seismogram with a maximum amplitude of 30 millimeters and a duration of about 33 seconds, the Antara news agency reported, citing the Mount Marapi Volcano Observation Post (PGA). Mount Marapi PGA officer Bilal Allegra Munbaits said the ash column was observed to be gray with thick intensity and drifting eastward. Mount Marapi is currently at Alert Level II status. The Center for Volcanology and Geological Hazard Mitigation warned of a potential threat of cold lava flows, especially for communities living along rivers originating from the volcano's peak. https://www.sott.net/article/505105-Indonesias-Mount-Marapi-erupts-spewing-ash-up-to-1-mile Thu, 12 Mar 2026 10:49:52 +0000 https://www.sott.net/article/505091-Hawaiis-Kilauea-volcano-erupts-shooting-lava-fountains-up-to-300-metres-high-43rd-eruption-since-December-2024 Kilauea is shooting lava fountains up to 300 metres high, and falling tephra is forcing temporary closures on Hawaii's Big Island.

The Echinus Geyser - located in the park's famous Norris Geyser Basin - had been in slumber since 2020, and it's unknown whether the eruptions will continue into the summer. Researchers say geysers can sometimes become active for a month or two before falling dormant again. "Geysers are always turning on and off. That's Yellowstone being Yellowstone!", the US Geological Survey wrote on X. https://www.sott.net/article/504962-Worlds-largest-acidic-geyser-wakes-up-in-Yellowstone-from-six-year-slumber Tue, 03 Mar 2026 21:05:56 +0000 https://www.sott.net/article/504917-Mount-Fuego-volcano-erupts-violently-in-Guatemala-Ash-rises-5000-meters One of the most active volcanoes in Central America, Volcán de Fuego in Guatemala, is once again showing intense volcanic activity today. 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. These events aren't visible to the average park visitor, but they can be dramatic when viewed... https://www.sott.net/article/504672-Yellowstones-supervolcano-is-creating-a-19-mile-bulge Mon, 16 Feb 2026 18:16:51 +0000 https://www.sott.net/article/504634-Seismic-activity-triggers-new-eruption-at-Reunions-active-volcano A powerful eruption of the Piton de la Fournaise volcano occurred on Friday, February 13, on Réunion Island, with lava activity observed south of the Dolomieu crater. According to the French agency Orange, the eruption was confirmed by the Piton de la Fournaise Volcanological Observatory (OVPF) and a scientific research institute involved in monitoring the volcano. Seismic activity intensified at approximately 9:25 a.m., marking the start of a seismic crisis, while volcanic tremors — indicating the upward movement of magma — were detected beginning at 10:00 a.m. Observatory director Aline Peltier said the eruption had been anticipated, noting that strong seismic activity and inflation of the volcano had been observed following a previous eruption a week earlier. "For us, this was not unexpected: following the last eruption a week ago, strong seismic activity and inflation of the volcano had been observed," she explained. https://www.sott.net/article/504634-Seismic-activity-triggers-new-eruption-at-Reunions-active-volcano Sat, 14 Feb 2026 20:29:05 +0000 https://www.sott.net/article/504632-Indonesias-most-active-volcano-Mount-Semeru-erupts Indonesia's most active volcano on Java Island roared back to life early Saturday, as multiple eruptions from Mount Semeru sent clouds of superheated ash and gas as high as nearly 6 kilometers, authorities said. The first significant eruption was recorded at 5:54 am local time, when intense and fast-moving mixtures of hot gas, volcanic ash and debris surged southeast toward the Besuk Kobokan river valley in East Java's Lumajang and Malang regencies. A dense grey ash column rose roughly 2,000 meters (6,561 feet) above the summit, according to volcanologists at the Mount Semeru observation post. A second eruption at 7:25 am produced another towering plume, this time reaching about 1,500 meters above the peak.

The volcano, which has been regularly erupting for over a year now, unleashed a lava fountain of more than 1,500 feet (460 meters) high into the air, with thick plumes of smoke and gases rising as high as 20,000 feet (6 kilometres). The recent eruption lasted nearly 10 hours, starting at 8:22 am and abruptly ending at 6:04 pm. Streams of lava poured from several vents within the Halemaʻumaʻu crater on Kilauea. The gas released during the eruption reacts in the atmosphere to form a visible haze known as vog—volcanic smog—which can trigger respiratory issues and other health problems. https://www.sott.net/article/504010-Stunning-video-captures-Hawaiis-Kilauea-volcano-unleashing-lava-fountain-on-January-12 Tue, 13 Jan 2026 11:00:49 +0000 https://www.sott.net/article/503990-Mount-Semeru-erupts-sending-pyroclastic-flow-5-km-from-peak-in-Indonesia Mount Semeru, located on the border of Lumajang and Malang Districts, East Java, erupted on Sunday night (Jan 12), sending pyroclastic flows -locally known as hot clouds- as far as five kilometers from the summit. "Mount Semeru erupted at 10:25 p.m. local time. The eruption consisted of a pyroclastic flow with a distance of approximately 5 km," an officer at the Mount Semeru Observation Post, Sigit Rian Alfian, said in a written report. The eruption column was observed to be approximately 2,000 meters above the summit, or 5,676 meters above sea level (masl). This latest activity follows a period of heightened unrest for the volcano, which has remained frequently active for several years. https://www.sott.net/article/503990-Mount-Semeru-erupts-sending-pyroclastic-flow-5-km-from-peak-in-Indonesia Mon, 12 Jan 2026 13:26:24 +0000 https://www.sott.net/article/503930-Heightened-activity-at-Mayon-Volcano-in-the-Philippines-raises-safety-concerns The Philippines' most active volcano, Mayon, is showing signs of escalating activity, prompting authorities to reinforce exclusion zones and warn of potentially dangerous eruptions, the Philippine Institute of Volcanology and Seismology (Phivolcs) said Thursday. Phivolcs said entry into the six-kilometer (3.7-mile) Permanent Danger Zone around the volcano is strictly prohibited, while aircraft have also been advised to avoid flying close to the summit. Nearly 50 pyroclastic flows -- fast-moving currents of hot gas, ash and volcanic debris -- were recorded over a 24-hour period, the agency added. Phivolcs Director Teresito Bacolcol warned of the deadly potential of such flows, recalling they killed 77 people during Mayon's 1993 eruption, according to the Philippine News Agency. https://www.sott.net/article/503930-Heightened-activity-at-Mayon-Volcano-in-the-Philippines-raises-safety-concerns Fri, 09 Jan 2026 13:52:52 +0000 https://www.sott.net/article/503891-Semeru-Volcano-in-Indonesia-erupts-31-times-in-6-hours Indonesia's Semeru Volcano Monitoring Station (PGA) in Lumajang regency, East Java Province, recorded 31 volcanic eruption-related earthquakes just within Tuesday morning. A report from the PGA Semeru Station at Mount Sawur showed that the eruption-related earthquakes had amplitudes of 11-22 mm and lasted 64-115 seconds, indicating that volcanic activity remains complex. Besides, the monitoring station also recorded one avalanche earthquake with an amplitude of 6 mm lasting 20 seconds, four wind-induced earthquakes, and two tremor events.

That's the word U.S. Geological Survey volcanic experts used to describe a muddy eruption at Black Diamond Pool in Yellowstone National Park on Saturday morning. Video shared by the USGS on social media shows mud spraying up and out from the pool just before 9:23 a.m. in Biscuit Basin about midway between park favorites Old Faithful and Grand Prismatic. Other recent eruptions have mostly been audible and not visible, because they happened either at night or when the camera was obscured by ice. The agency said the Black Diamond Pool was previously the site of a hydrothermal explosion, in July 2024, that sent rocks and mud flying hundreds of feet high and damaged a boardwalk. It prompted the closure of the area to visitors due to the damage and the potential for additional hazardous activity. So-called dirty eruptions reaching up to 40 feet (about 12 meters) have occurred sporadically since then. https://www.sott.net/article/503607-Muddy-eruption-at-Yellowstones-Black-Diamond-Pool-captured-on-video Mon, 22 Dec 2025 18:20:02 +0000 https://www.sott.net/article/503602-Indonesia-Mount-Semeru-erupts-sending-ash-3900ft-into-air-as-flowing-mud-devastates-towns A huge volcano has sent an enormous 3,937ft column of ash into the air after erupting six times in one day.
