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

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

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.

Supervolcano in Italy showing signs of waking up

The Phlegraean Fields, now considered one massive supervolcano, are beginning to stir, making the scientific community uneasy.

These volcanic fields, nestled just west of Naples, Italy, are among the top eight emitters of volcanic carbon dioxide worldwide.

Since 2005, one spot in particular — the Solfatara crater — has been releasing increased volumes of gas, catching the attention of researchers and locals alike.

Gas emissions at Solfatara crater

Gianmarco Buono, a volcanologist at the Italian National Institute of Geophysics and Volcanology (INGV), is leading a study to understand what's behind this surge in gas emissions.

"Estimating the source of the carbon dioxide is important to properly reconstruct what is happening in the magmatic system and the hydrothermal system," says Buono.

His team aims to provide a tool that can distinguish between carbon dioxide coming from magma and that released by other processes, a method that could be useful in volcanic regions around the world.

Mount Dukono in North Halmahera, North Maluku, spewed an ash column up to 3,000 meters above the summit on Sunday afternoon at 2:24 p.m. local time.

Sarjan Roboke, an officer of the PGA for Dukono Volcano, said in a press statement that the erupted ash column was white to gray with a thick intensity and tended to move west to northwest.

A series of earthquake tremors was recorded from the volcano, which stands at 1,335 meters above sea level, with a maximum amplitude of 27 and lasting for 4 minutes and 53 seconds.

The current status of the volcano is Level II/Alert.

Roboke called on local residents to avoid a 3-kilometer radius from the peak of the volcano and to wear masks outdoors to protect their respiratory systems from volcanic ash.

A volcano on the Reykjanes Peninsula in Iceland has erupted for the seventh time since December, prompting evacuation orders.

Orange lava gushed from a fissure almost two miles long after the eruption started with little warning just after 11pm on Wednesday.

People living in about 50 houses nearby were told to leave, along with guests at the popular Blue Lagoon spa resort southwest of Reykjavik, national TV station RUV said.

While the eruption does not pose a threat to air travel, the authorities warned of gas emissions across parts of the peninsula, including the nearby town of Grindavik.

Repeated volcanic eruptions close to the town, which has a population of 3,800, have damaged infrastructure and property and forced many residents to leave for their own safety.

The Semeru volcano, located in Indonesia's Java, erupted again early on Monday at 03:35 a.m. local time, spewing thick grey ash up to 1 kilometre above its summit.

"This eruption was recorded by a seismograph with a duration of 122 seconds and a significant maximum amplitude," said Ghufron Alwi, an officer at the Semeru Volcano Observation Post.

Earlier, at 01:47 a.m. local time, a similar eruption occurred with a duration of 146 seconds and an ash column height of 1 kilometre, indicating high volcanic activity in the past few hours, Xinhua news agency reported.

From January until November 11, 2024, Mount Semeru has erupted 1,738 times, with volcanic activity dominated by eruption tremors, signaling continuous magma pressure beneath the surface.
