 Alaska's Mount Spurr is exhibiting indications of increased activity, prompting scientists to warn that the volcano might be poised to erupt for the first time in 30 years.

 The Alaska Volcano Observatory (AVO) has observed steady and ongoing ground swelling, which indicates possible magma buildup underneath.


 The AVO stated that an eruption is "possible within the coming weeks or months, though it is not guaranteed."

<h2>
 
 Why It Matters
 
</h2>

 Located approximately 80 miles west of Anchorage, Alaska’s largest city by population, Mount Spurr is among the state's most monitored volcanoes. Its last eruption occurred in 1992, covering south Alaska with ash and disrupting aviation services.


 When that volcano erupted, Anchorage International Airport closed down for 20 hours. If such an incident happened again, we might face comparable consequences.

<h2>
 
 What To Know
 
</h2>

 The Alaska Volcano Observatory has confirmed that Mount Spurr is exhibiting signs of activity.
 indications of revived volcanic activity
 including heightened levels of gas emissions, increased seismic activity, and observable ground deformations.


 On March 7, overflights recorded a sulfur dioxide emission rate of approximately 440 tons daily. Additionally, elevated levels of carbon dioxide were observed both at the summit and near the Crater Peak vent.


 "The ongoing disturbances at Mount Spurr suggest that fresh magma has penetrated the Earth's crust under the volcano, thereby increasing the likelihood of an eruption," stated the AVO update.


 Chances are high that magma has been building up under the summit of Mount Spurr over several months now. Recent gas readings indicate that a new route might have formed toward the Crater Peak vent, allowing fresh magma to ascend and potentially cause an eruption at this location. All recorded eruptions have taken place at Crater Peak. The most recent documented eruption from the top of Spurr happened thousands of years ago.


 The AVO indicated that it was probable the area might experience an explosive eruption akin to those in 1953 and 1992, each originating from the Crater Peak vent and lasting several hours.


 These past eruptions propelled ash clouds for hundreds of miles downwind and left behind as much as a quarter-inch layer of ash over portions of southern-central Alaska. The upper Chakachatna River Valley might be impacted by pyroclastic flows and mudflows, also known as lahars.

 What People Are Saying
 
</h2>

 
 The Department of the Interior
 
 
 said on X
 
 
 in February:
 
 Experts specializing in volcanoes are keeping a close eye on Mount Spurr in Alaska due to an ongoing sequence of minor, shallow seismic events under the volcano, which suggest continued eruptive activity. Aerial footage captured on February 7, 2025, reveals a tiny lake situated within the snow-covered crater.

<h2>
 
 What Happens Next
 
</h2>

 The AVO states they intend to carry out regular flyovers to assess gas emissions, examine surface alterations, and gauge ground temperature levels.


 "The consideration includes installing extra surveillance equipment due to the ongoing instability," it stated.

 Scientists have identified early warning signs of a potential volcanic eruption at
 Mount Spurr
 , located in Alaska.
 


 The most recent eruption took place in 1992; however, the volcano has displayed growing activity in the past several months. As reported by
 Alaska Volcano Observatory
 Now, an eruption seems probable according to AVO.


 Specialists at the observatory believe that an eruption might happen within just three weeks. In their latest document, they stated that a "
 robust plume
 had been noticed at the volcano's peak.


 The
 AVO
 mentioned in its most recent update: "
 The rise in gas emissions suggests that fresh magma has entered the Earth's crust under the volcano, indicating that while an eruption could happen within the coming weeks or months, it is not guaranteed.
 ."


 Nevertheless, researchers pointed out that the plume by itself does not automatically indicate an imminent eruption.


 "
 These findings, combined with the advantageous atmospheric conditions, indicate that the strong plume from Mount Spurr in recent days likely did not stem from heightened volcanic activity.

Rock from 4,200,000,000 years ago confirms something we wondered about the moon

 Volcanoes erupted on the mysterious far side of
 the moon
 billions of years ago, new research confirms.
 


 Scientists analysed lunar soil brought back to Earth from
 China
 ’s Chang’e-6 spacecraft, the first to return with a haul of rocks and dirt from the little-explored far side.


 Two separate teams found fragments of volcanic rock that were about 2.8 billion years old. One piece was even more ancient, dating back to 4.2 billion years.


 ‘To obtain a sample from this area is really important because it’s an area that otherwise we have no data for,’ said Christopher Hamilton, a planetary volcano expert at the University of Arizona.


 Scientists know there were active volcanoes on the near side, the part of the moon seen from Earth, dating back to a similar time frame.


 Previous studies, including data from NASA’s Lunar Reconnaissance Orbiter, suggested the far side might also have a volcanic past.

 The first samples from that region facing away from Earth confirm an active history. The results were published Friday in the journals Nature and Science.


 China has launched several spacecraft to the moon.


 In 2020, the Chang’e-5 spacecraft returned moon rocks from the near side, the first since those collected by NASA’s Apollo astronauts and Soviet Union spacecraft in the 1970s.


 The Chang’e-4 spacecraft became the first to visit the moon’s far side in 2019.

 The moon’s far side is pockmarked by craters and has fewer of the near side’s flat, dark plains carved by lava flows.


 Why the two halves are so different remains a mystery, said study co-author Qiu-Li Li from the Chinese Academy of Sciences.


 Li said the new findings reveal over one billion years of volcanic eruptions on the lunar far side.


 Future research will determine how the activity lasted so long.
