Mount Spurr near Anchorage has been showing signs of unrest for a year. Now scientists think it's creeping closer to an eruption.

A huge volcano in Alaska appears to be "moving closer to an eruption," scientists monitoring it have said.

Mount Spurr, which sits 81 miles (130 kilometers) west of Anchorage, is now releasing unusual levels of volcanic gases near its summit and from a flank vent that last erupted in 1992.

The 11,000-foot (3,370-meter) volcano has been undergoing an uptick in earthquakes and snow and ice melt on its slopes in the past year, indicating magma movement under the surface. Now, according to scientists at the Alaska Volcano Observatory (AVO), it's most likely that this unrest will end in an eruption.

Mount Semeru in Indonesia erupts 6 times, spewing ash up to 1 kilometer

Indonesia's Mount Semeru reportedly erupted again on Monday morning, March 17, 2025. The height of the eruption column that occurred at 08:11 AM WIB (Western Indonesian Time) was observed to be approximately 1,000 meters above the summit (approximately 4,676 meters above sea level).

"The ash column was observed to be white to gray with moderate intensity towards the southeast. At the time of this report, the eruption is still ongoing," said Liswanto, an officer of the Semeru Volcano Monitoring Post (PGA) in his written report on Monday morning, March 17, 2025.

Based on observations from the PGA Post located at Mount Sawit, Sumber Wuluh Village, Candipuro District, Lumajang Regency, there were six eruptions on Monday morning. Meanwhile, based on observations in the last 24 hours until early Monday morning, several types of seismic activity were recorded. This includes 52 times of eruption earthquakes, 3 times of avalanche earthquakes, 19 times of gust earthquakes, 4 times of harmonic earthquakes, and 1 time of volcanic earthquake.

Guatemalan authorities evacuated around a thousand people on Monday after Central America's most active volcano erupted, spewing lava, ash and rocks.

Residents with traumatic memories of a deadly eruption in 2018 sought refuge after the Fuego volcano exploded spectacularly 35 kilometers (22 miles) from the capital Guatemala City.

"We heard the rumblings and then a strong eruption," Manuel Cobox, 46, told AFP after leaving his home with his wife and three daughters.

Some 125 families, around 900 people, were moved to safety from the community of El Porvenir, said Juan Laureano, a spokesman for Guatemala's disaster coordination agency, Conred.

Residents of another community in Las Lajitas were also evacuated, the official added.

Comment: Stream from March 9, 2025:

Shockwave at 2:37 - An explosion is heard from the shockwave which was powerful enough to shake the camera that is 8km (5 miles) away.

New findings date Los Chocoyos supereruption to 79,500 years ago, and show Earth bounced back within decades

An international team of Earth and life scientists, hydrologists, chemists, and physicists, has found evidence showing that the Los Chocoyos supereruption occurred approximately 79,500 years ago and that the planet bounced back from its chilling effects within decades.

In their paper published in the journal Communications Earth & Environment, the group describes how they studied ice core samples obtained from places in Greenland and Antarctica to learn more about the global impact of the ancient volcanic eruption.

Prior evidence has shown that a massive eruption occurred in what is now Guatemala's Atitlán volcanic system tens of thousands of years ago, spewing ash far into the atmosphere. So much ash was emitted, it has been thought, that it led to an ice age. Today, the eruption is known as the Los Chocoyos supereruption.

Mount Semeru erupts in East Java, Indonesia - ash column reaches 1,100 meters

Mount Semeru in East Java erupted on Wednesday evening, February 26, 2025. The observed ash column reached approximately 1,100 meters above the peak or around 4,776 meters above sea level.

The eruption of the highest volcano on the island of Java occurred at 17:30 WIB (Western Indonesian Time). The observed ash column was white to gray with moderate intensity leaning towards the north. This eruption was recorded on a seismogram with a maximum amplitude of 22 mm and a duration of approximately 2 minutes 16 seconds.

One hour later, at 18:29, the volcano with a height of 3,676 meters above sea level erupted again with an observed ash column height of approximately 900 meters above the peak (approximately 4576 meters above sea level). The observed ash column was white to gray with thick intensity towards the south and southwest. This eruption was recorded on a seismograph with a maximum amplitude of 23 mm and a duration of 163 seconds.

The Coming Volcanic Winter?

QUESTION: Marty, Your computer warned that we would be heading into global cooling, not warming. But you also warned that we would see increased volcanic activity and the risk of a volcanic winter. Well, this has been the coldest winter I can remember. With Mt Spurr stirring, another offshore from California, and some hinting at Yellowstone erupting, do you have any update on this aspect from Socrates?

ANSWER: Nothing has changed. We are heading into a more active volcano period, and that does raise the risk of a volcanic winter in which crops fail, and there will be a shortage of food. I still recommend that you stockpile two years' worth of food. It is not that you will save money, but that the supply may be seriously diminished. Our models of Wheat warn that this year is the Directional Change, and we can see a shortage into 2028.

Mount Lewotobi Laki-Laki's eruption triggers highest alert level in Indonesia

Indonesia raised the volcanic alert status of Mount Lewotobi Laki-Laki on Flores Island to the highest level on Thursday following a surge in volcanic activities.

The volcano has reportedly been erupting continuously for several days, News.Az reports, citing Xinhua.

"Deep volcanic earthquakes have increased significantly. This indicates that the intensity of magma activity in Mount Lewotobi Laki-Laki's magma chamber is rising and moving toward shallower depths," said Muhammad Wafid, head of the geology agency at the Ministry of Energy and Mineral Resources.

The agency has urged the public to remain alert and avoid the 6 km radius danger zone. It also advised heightened vigilance in a 7 km extended danger zone in the southwestern and northeastern sectors due to the increased risk of sudden and hazardous phreatic eruptions.

Mount Lewotobi Laki-Laki is one of Indonesia's 127 active volcanoes.

Fire and ice: lava meets snow in spectacular night eruption of Mount Etna

mmmmmm
At approximately 3,300 meters high, the lava flow is still seeping from a crack that formed on the southern slope of the "Bocca Nuova" crater on Saturday evening.
Mount Etna on Monday (February 10) staged a mesmerising spectacle with lava spewing from the Bocca Nuova crater, illuminating the snowy surroundings of the volcano's summit.

The National Institute of Geophysics and Volcanology of Catania located the emission of lava at an estimated altitude of about 3,000 metres above sea level between the base of the Bocca Nuova crater and the South-East crater.

According to volcanologists, the current eruption is a typical sub-terminal eruption as it comes from a fracture and not from one of the main craters.

The 3,330-metre-high volcano is the tallest in Europe, and is believed to have the longest documented history of eruptions among all volcanoes, with records dating back to 425 B.C.

Sakurajima unleashed a powerful explosion at 8:13 p.m. on January 30, sending a towering plume of ash 2,700 meters above the crater.

This marks the volcano's 22nd explosive eruption of 2025, adding to its intense activity.

Witnesses also reported a rare display of volcanic lightning, illuminating the darkened skies as the eruption unfolded.
