What can be said is that we are living in the warmth of an interglacial period known as the Holocene Epoch, which began about 11,700 years ago. It followed a frigid span of nearly 90,000 years, when thousands of feet of glacial ice covered Canada and northernmost parts of the region that would become the U.S. Temperatures were lower than the current average by 11 to 14 degrees Fahrenheit. The relatively benign Holocene of nearly 12 millennia has been punctuated by intermittent temperature changes, including 10 warming periods, counting our current one. The most recent era of cold was the Little Ice Age from about 1250 to 1850. Climate alarmists treat the "preindustrial" era before 1850 as their starting point for measuring modern temperature, without noting that the period... https://www.sott.net/article/508602-Climates-past-performance-uncertain-predictor-of-future Sat, 26 Sep 2026 21:42:43 +0000 https://www.sott.net/article/508601-Italys-Catania-Airport-suspends-flights-as-Mount-Etna-sends-ash-cloud-4km-high Italy's Catania Airport has suspended all incoming flights until 4pm local time after renewed activity from Mount Etna sent volcanic ash several kilometres into the atmosphere. The airport operator said the suspension was imposed because of the release of volcanic ash, with the eruption activity affecting airspace around the Sicilian airport. Earlier restrictions had reduced the airport's capacity to four landings an hour, compared with the normal 12, before arrivals were suspended completely. 4km-high ash cloud reported Volcanic ash was reported emerging from Mount Etna's north-east crater and dispersing towards the south. According to measurements from Italy's National Institute of Geophysics and Volcanology (INGV), the ash plume reached around 4km in height. https://www.sott.net/article/508601-Italys-Catania-Airport-suspends-flights-as-Mount-Etna-sends-ash-cloud-4km-high Sat, 26 Sep 2026 18:46:24 +0000 https://www.sott.net/article/508600-Mud-volcano-erupts-in-Azerbaijans-Garadagh An eruption was recorded on September 26, 2026, at a mud volcano located on the border of Azerbaijan's Garadagh and Gobustan districts. The eruption was recorded by digital seismic stations of the Republican Seismic Survey Center under ANAS, the Center told APA. The eruption occurred at 07:32 local time, was characterized by one phase and lasted 10 minutes. A column of flame was observed during the eruption. The event was recorded by eight seismic stations. The eruption source was located at a depth of 4 km. The amount of energy released during the eruption was estimated at 6.50 × 10^6 joules. https://www.sott.net/article/508600-Mud-volcano-erupts-in-Azerbaijans-Garadagh Sat, 26 Sep 2026 18:27:03 +0000 https://www.sott.net/article/508570-Worlds-largest-archipelago-has-two-new-islands-after-volcanic-eruptions-in-Indonesia Indonesia's Geological Agency under the Ministry of Energy and Mineral Resources (ESDM) has reported the emergence of two new islands northwest and southeast of Mount Anak Krakatau in the Sunda Strait following a series of eruptions earlier this month. Acting Director of the Geological Agency Lana Saria said the emergence of the two islands was confirmed based on reports from sailors and volunteers, as well as analysis of Sentinel satellite imagery through Sept. 23. One island is about 760 meters northwest of Anak Krakatau's shoreline, while the other lies about 495 meters southeast of the volcano. The two islands are aligned along a Northwest - Southeast axis, with the volcano's main crater located between them. Possessing the longest coastline in Southeast Asia, Indonesia also has the largest number of islands in the world and is famous for its sacred temples and unique culture. https://www.sott.net/article/508570-Worlds-largest-archipelago-has-two-new-islands-after-volcanic-eruptions-in-Indonesia Fri, 25 Sep 2026 17:59:23 +0000 https://www.sott.net/article/508429-Five-new-vents-open-at-Kilauea-volcano-summit-in-Hawaii There have been some changes in the current eruption at Kilauea volcano. New vents opened Monday night, north of the established vent complex in the summit caldera. The vents opened without significant seismicity, although there was a short-lived swarm of shallow earthquakes in the same region on the night of September 13th. The new vents are at a lower elevation than the main eruptive vent complex. On Tuesday, the USGS Hawaiian Volcano Observatory reported a total of five new vents have formed, and provided an annotated image showing the exact locations. https://www.sott.net/article/508429-Five-new-vents-open-at-Kilauea-volcano-summit-in-Hawaii Thu, 17 Sep 2026 12:39:18 +0000 https://www.sott.net/article/508250-Anak-Krakatau-eruption-ash-column-reaches-15km-high-in-Indonesia Indonesia's Anak Krakatau volcano sent ash approximately 15 kilometres high during an eruption that continued into Saturday, September 5, while Japan subsequently confirmed that the event would have no tsunami impact on the country. The Japan Meteorological Agency (JMA) issued the assessment at 12.30pm Japanese time, or 10.30am in Thailand and western Indonesia, according to an updated Weathernews report. No significant sea-level changes had been observed at monitoring stations in Japan or overseas. Japan had earlier begun checking for possible tsunami effects following the eruption. Indonesian authorities meanwhile maintained a three-kilometre exclusion zone around the active crater and urged coastal communities to remain calm. https://www.sott.net/article/508250-Anak-Krakatau-eruption-ash-column-reaches-15km-high-in-Indonesia Sat, 05 Sep 2026 12:04:16 +0000 https://www.sott.net/article/508163-Sinabung-volcano-in-Sumatra-Indonesia-erupts-with-a-column-of-thick-ash-3500-meters-high Mount Sinabung on Indonesia's Sumatra island has erupted, spewing a column of black ash into the sky.

As the collapse begins, people near the camera can be heard gasping and reacting in amazement as the mountainside suddenly erupts in an intense orange glow. Huge quantities of incandescent material pour from Merapi's unstable lava dome and cascade down the steep southwestern flank. The event provides a dramatic view of the process that makes Merapi particularly dangerous: viscous lava accumulates at the summit, forming steep and unstable lava domes. When portions of these domes collapse, they can produce incandescent lava avalanches and, during larger events, fast-moving avalanche-generated pyroclastic flows (awan panas guguran). https://www.sott.net/article/508133-Dome-collapse-at-Mount-Merapi-volcano-in-Indonesia-sends-down-pyroclastic-flow Sat, 29 Aug 2026 14:44:09 +0000 https://www.sott.net/article/508106-Mount-Lewotobi-in-Indonesia-erupts-again-ash-column-2500-meters-above-peak-4301-volcanic-eruptions-nationwide-so-far-in-2026 Mount Lewotobi Laki-laki in East Nusa Tenggara erupted again on Thursday (27/8/2026) at 08.30 WITA. This volcano has erupted 8 times in the last week.

Europe's tallest and most active volcano has been erupting continuously since August 6, producing lava fountains, fresh flows, and persistent ash emissions. Experts say the activity could continue for weeks or even months. Volcanic ash has caused the greatest disruption, with shifting winds carrying it toward Catania-Fontanarossa Airport, about 30 km south of Etna. On Tuesday, the airport extended restrictions due to "Etna's eruptive activity and the simultaneous emission of volcanic ash," limiting arrivals to ten per hour.

Situated on the Caribbean Island of Martinique, Mount Pelée erupted on May 7, 1902, sending a flow of hot gas, ash, and rocks through the nearby hub of Saint-Pierre, killing nearly 30,000 people in a single afternoon. This made it the third deadliest volcanic eruption of the 20th century. Were Mount Pelée to erupt today, the resultant pyroclastic flows could reportedly put the 400,000 people who live on Martinique at risk while ashfalls could disrupt electricity and ground flights, per a 2021 study. While the volcano has been dormant since 1932, it showed signs of unrest with experts detecting 124 earthquakes between July 24 and July 31 — nearly three times the number picked up the week prior, per the Martinique Volcanological and Seismological Observatory. https://www.sott.net/article/507771-Eruption-of-deadly-volcano-that-wiped-out-30000-people-in-1902-cannot-be-excluded-after-recent-activity-scientists Thu, 06 Aug 2026 12:21:57 +0000 https://www.sott.net/article/507756-Sakurajima-volcano-in-Japan-erups-on-August-2-ash-plume-9842-feet-high The Sakurajima volcano erupted this past weekend in Japan with plumes of smoke as high as 9,842 feet. https://www.sott.net/article/507756-Sakurajima-volcano-in-Japan-erups-on-August-2-ash-plume-9842-feet-high Wed, 05 Aug 2026 12:41:04 +0000 https://www.sott.net/article/507736-Intense-eruption-continues-at-Fuego-Volcano-Guatemala According to the latest special bulletin from INSIVUMEH, the eruption began at approximately 8:30 a.m. and remained underway more than 11 hours later. Monitoring instruments showed additional increases in energy associated with the forceful expulsion of volcanic material and the descent of pyroclastic density currents. Intense emissions of gas, ash and incandescent material continue from the crater. Ash columns have reached approximately 5,000 to 6,000 metres above sea level—about 16,400 to 19,700 feet—and are being carried westward from the volcano. Pyroclastic flows have descended several ravines, particularly the Seca and Ceniza ravines. These extremely hot, fast-moving mixtures of ash, rock and volcanic gases are the principal danger during the eruption. INSIVUMEH warns that communities located approximately 7 to 10 kilometres from the crater—particularly around San Pedro Yepocapa and the western and southern flanks—could be at risk if larger flows occur.

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.

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.

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.

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.

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 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.
