Experts on high alert as 100 volcanoes in Antarctica edge closer to erupting

Experts are on red alert after uncovering a ticking time bomb in Antarctica that would reshape the continent and dramatically increase sea levels worldwide.

More than 100 volcanoes lie beneath the surface of the West Antarctic Ice Sheet, which is 'particularly vulnerable to collapse, yet its position atop an active volcanic rift is seldom considered,' the study noted.

Scientists have warned that as climate change causes the ice sheet to melt, this drives increased volcanic activity that speeds up melting at the surface, creating a 'positive feedback loop.'

As the ice sheet melts, the amount of mass pushing down on the surface decreases, which creates an uplifting effect in the subsurface.

Kanlaon volcano in the Philippines spews ash anew on January 13

llllllll
Kanlaon Volcano expels ash at 10:25 a.m. on January 8, 2025.
Amid the threat of another eruption, Kanlaon Volcano on Negros Island twice emitted ash yesterday, the Philippine Institute of Volcanology and Seismology said.

Phivolcs noted that ash emissions lasted 10 to 47 minutes, reaching as high as 500 meters with a west and west-southwest drift.

"This event generated grayish plumes that rose 500 meters above the crater before drifting west as recorded in the Mansalanao La Castellana station and Kanlaon Volcano Observatory in Canlaon City," the agency said.

Phivolcs measured the release of sulfur dioxide to be at 5,640 tons per day. Its observations centers recorded at least 22 volcanic earthquakes over a 24-hour period.

Taal Volcano spews 900-meter plume in the Philippines on January 10

mmmmm
Taal Volcano in Batangas spewed a 900-meter plume late Friday night following a phreatic eruption, the Philippine Institute of Volcanology and Seismology (PHIVOLCS) said.

The phreatic eruption from Taal Volcano Island's Main Crater, which occurred at 11:51 p.m., was accompanied by a volcanic tremor that lasted three minutes.

Phreatic eruptions are steam-driven explosions that occur when water beneath the ground or on the surface is heated by magma, lava, hot rocks, or new volcanic deposits, according to PHIVOLCS.

Alert Level 1 (Low-level unrest) prevails over the volcano.

Mount Ibu volcano erupts in Indonesia sending ash 5km high on January 11

mmmmm
Mount Ibu Volcano sent a 5km high ash column above its crater when it erupted in Indonesia on Saturday night. Footage shows the hot lava flowing from its peak, as seen from a home in North Maluku on the evening of January 11.

Authorities recorded the eruption at 7:35 pm local time, with the ash column height reaching 5,325 metres with thick intensity leaning towards the west. The eruption lasted more than three minutes with a maximum amplitude of 28 mm.

Lava was ejected 2km from the centre with alert level 3 status. Locals and tourists are prevented from entering a 4km radius danger zone, while residents near the area are advised to use face masks and goggles.

Indonesia is in the Pacific Ring of Fire, a geologically active area with frequent earthquakes and volcanic activity. It has more than 130 active volcanoes, making it one of the most volcanically active countries in the world.

West Sumatra's Mount Marapi erupts, spewing ash in Indonesia

mmmmmmm
Mount Marapi in West Sumatra erupted again on Saturday morning, January 4, 2025, spewing a 1,000-meter-high ash column. One of the officers at the volcano's observation post, Trian Ahmadi, recorded the eruption.

"The ash column is observed to be gray, thick in intensity, and inclined to the north and northeast," he said in an official statement after the incident.

According to Trian, the volcano eruption was recorded on a seismogram with a maximum amplitude of 30.3 millimeters for 1 minute 40 seconds.

"The eruption is still ongoing as this report is being made," he said at 09:51, on Saturday.

He confirmed that Mount Marapi is still on alert. The monitoring team has asked locals, tourists, and climbers to stay away from the area within a 3km radius of the Verbeek crater.

People are urged to use masks covering the nose and mouth to avoid respiratory problems. People living high up in the valley and along the banks and rivers flowing from the summit of Mount Marapi are also advised to be aware of the threat of cold lava. "Especially during the rainy season," Trian said.

Dofen mountain (Afar region, Ethiopia): volcano in the area of ongoing quakes starts erupting jets of steam and mud

A new vent producing a powerful jet of gas, rocks and mud has been observed at Dofen volcano in Dulecha district a short time ago. This is the area closest to the ongoing seismic swarm in Ethiopia's Afar region, which we suspect to be caused by the intrusion of magma.

The embedded video below although not clear enough to see much details shows what might be phreatic or hydrothermal explosive activity, when ground water is heated by fluids from magma underneath and flashes to steam, escaping in this case from an open ground crack. It is not entirely clear if a vent had existed at the site before or if it opened recently.

There are no further details available immediately, but this clearly is a sign of escalation of the crisis and strongly hints that a volcanic eruption could be in the making.

One of the world's most active volcanoes — Hawaii's Kilauea — is erupting again

Hawaii’s Mount Kilauea, one of the most active volcanoes on Earth launched jets of molten lava skywards during a spectacular eruption.
Hawaii’s Mount Kilauea, one of the most active volcanoes on Earth launched jets of molten lava skywards during a spectacular eruption.
Lava began bubbling Monday through the crust of one of the world's most active volcanoes — Kilauea, on Hawaii's Big Island.

The eruption was confined to the volcano's summit caldera, in a remote, closed area of Hawaii Volcanoes National Park, the Hawaii Volcano Observatory reported. Increased earthquake activity began at about 2 a.m. local time and within about half an hour webcam images began to show lava emerging through fissures in the caldera or spurting in fountains.

The most immediate threat was from volcanic smog that could reach homes downwind, the observatory said. Such "vog" contains sulfur dioxide and can worsen symptoms for people who have conditions like asthma, other respiratory issues or cardiovascular disease.

The area where the eruption is occurring has been closed to the public since 2007 due to hazards that include crater wall instability, ground cracking and rockfalls.

Hawaii Volcanoes National Park encompasses the summits of two of the world's most active volcanoes: Kilauea and Mauna Loa. Kilauea also erupted in June and September.

Mount Kanlaon volcano eruption sends villagers fleeing for safety as homes are blanketed in ash in the Philippines

MMMMMMM
A plume of hot ash and gases up to 3 kilometers (1.8 miles) high forced residents to seek shelter after a volcano in the Philippines erupted on Monday.

There were no immediate reports of casualties in the latest explosion of Mount Kanlaon, on central Negros island, but authorities shut schools and imposed a nighttime curfew after ash falling in several villages clouded the the visibility of motorists and sparked health concerns.

"It sounded like a cannon," Mayor Jose Chubasco Cardenas of Canlaon city, which lies southeast of the volcano, told The Associated Press by telephone. "There have been quiet eruptions before, but this was one very loud."

Disaster-response officials raised the danger level around Kanlaon due to "a greater risk of hazardous volcanic activity" and ordered villagers within a 6-kilometer (3.7-mile) radius of the crater to be evacuated.

This Week in Volcano News; Mammoth Mountain earthquake swarm, large Dukono eruption

mmmm
This week, an unusual earthquake swarm occurred at California's Mammoth Mountain volcano, involving more than two dozen events. Meanwhile, in Indonesia, the largest eruption plume on record was generated due to a plug bursting at the Dukono volcano. And, in Sumatra, the Dempo volcano was the site of a likely shallow magmatic intrusion that evaporated a portion of its acidic crater lake.

This video will discuss these stories and list the 48 volcanoes which are actively erupting around the planet.
