Imagine a volcano silent for a quarter of a million years. Now picture it showing signs of life.That’s the unsettling reality unfolding at Uturuñcu, a towering peak in the Bolivian Andes, and scientists are racing too understand what it means.
Located at over 20,000 feet,Uturuñcu has long been a geological enigma. After 250,000 years of apparent dormancy, it’s exhibiting tremors and gas emissions, hinting at a potential reawakening. Is this just a geological hiccup, or a prelude to something far more significant?
Unlocking Uturuñcu’s Secrets: A Global Scientific Effort
An international team of researchers has embarked on a mission to decipher Uturuñcu’s behavior. Their approach? A combination of cutting-edge seismology, advanced physical modeling, and detailed chemical analysis of the volcano’s rocky underbelly. Think of it as a high-tech geological autopsy.
Seismic Tomography: Peering Beneath the Surface
To understand the forces at play beneath Uturuñcu, the team analyzed over 1,700 seismic events. This data was used to create high-resolution images of the Earth’s crust under the volcano using a technique called seismic tomography. It’s like a CAT scan for the Earth.
The principle is straightforward: seismic waves travel at different speeds depending on the materials they pass through. By measuring these variations, scientists can map the structure of the subsurface.
The “Sombrero” Deformation: An Ominous Sign?
The seismic tomography revealed a peculiar “sombrero” deformation of the terrain. The center of the area is lifting, while the surrounding regions are slowly sinking. This unusual pattern raises concerns about the stability of the area and the potential impact on nearby communities.
This deformation isn’t just a geological curiosity; it could have serious consequences for the villages nestled in the shadow of Uturuñcu. The lifting and sinking could trigger landslides, ground fissures, and other hazards.
The “Zombie” volcano: Internal Circulation,Not ascent?
The researchers believe that Uturuñcu’s activity might be due to internal circulation of heated liquids and gases accumulated in shallow reservoirs under the crater. This “zombie” behavior suggests that the volcano is being reawakened by internal processes, without a large-scale ascent of magma – at least for now.
This is a crucial distinction. if the activity is driven by internal circulation, it might be less likely to lead to a major eruption. However, the scientists caution that even slow awakenings can turn brutal in the unpredictable world of volcanoes.
A New Method for Monitoring Inactive Volcanoes
The Uturuñcu study has broader implications beyond Bolivia. The researchers have demonstrated that combining geophysics, geology, and modeling can provide valuable insights into volcanoes that are considered inactive. This is notably important because many volcanoes around the world display a deceptive calm.
Earth is home to over 1,400 potentially active volcanoes. Many of these volcanoes exhibit a deceptive calm, similar to Uturuñcu. The methodology used in this study could serve as a new monitoring tool to avoid disasters in other at-risk regions.
International Collaboration: A Key to Understanding Volcanic Threats
this scientific achievement was made possible through collaboration between researchers from China, the United Kingdom, and the United States. Experts from the University of Oxford, the University of Sciences and Technologies in China, and Cornell University pooled their expertise in seismic imaging, physical modeling, and chemical analysis.
This synergy highlights the importance of international collaboration in addressing complex scientific challenges. Even in the face of geological upheavals, the best weapon remains international cooperation.
Towards a Finer Understanding of “Zombie” Volcanoes
The Uturuñcu study, published in the journal PNAS, marks a new chapter in understanding so-called “zombie” volcanoes: sleeping giants that are never truly dead.While a full-scale eruption of Uturuñcu may not be imminent, it’s unusual behavior provides a valuable possibility to better anticipate the geological dangers that surround us.
Vigilance is key. Even if Uturuñcu’s complete awakening isn’t for tomorrow, its abnormal behavior provides a precious window to better anticipate the geological dangers that surround us. This research underscores the need for continuous monitoring and advanced modeling to understand the complex dynamics of these potentially hazardous volcanoes.
The Most Watched Volcanoes in the World in 2025
Uturuñcu isn’t the only volcano under close scrutiny. Here’s a look at some of the other volcanoes that are being closely monitored around the world in 2025:

Super-Volcanoes like Yellowstone and Phlegrean fields are particularly followed to prevent large-scale disasters.
The inclusion of Yellowstone on this list is particularly relevant for American readers.The potential for a large-scale eruption at Yellowstone has been a topic of concern and scientific study for decades. The USGS actively monitors Yellowstone, and research efforts are ongoing to better understand the volcano’s behavior and assess the potential risks.
FAQ: Understanding Zombie Volcanoes and Volcanic Risk
What is a “zombie” volcano?
A “zombie” volcano is a volcano that has been dormant for a long period but shows signs of reawakening, such as increased seismic activity or gas emissions. It’s like a sleeping giant that’s starting to stir.
How do scientists monitor volcanoes?
Scientists use a variety of techniques to monitor volcanoes,including seismology (measuring earthquakes),ground deformation monitoring (measuring changes in the shape of the ground),gas emission monitoring (measuring the amount and type of gases released),and satellite observation.
What are the signs of an impending volcanic eruption?
Signs of an impending volcanic eruption can include increased frequency and intensity of earthquakes, changes in gas emissions, ground deformation, and increased heat flow.
can volcanic eruptions be predicted?
While it’s not possible to predict volcanic eruptions with certainty, scientists can assess the likelihood of an eruption based on monitoring data and historical patterns. This data is used to issue warnings and prepare for potential eruptions.

Is Uturuñcu About to Blow? expert Insights on “Zombie Volcanoes”
Time.news: Welcome, Dr. Anya Sharma! Thank you for joining us today to discuss the engaging but concerning situation unfolding at Uturuñcu, the so-called “zombie volcano” in Bolivia. For our readers unfamiliar, can you explain what makes Uturuñcu so unique and potentially dangerous?
Dr. Anya Sharma: Absolutely. Uturuñcu is a stratovolcano located at a very high altitude in the Andes.What makes it particularly fascinating, and worrying, is its long period of dormancy – around 250,000 years. The recent signs of activity – seismic tremors and gas emissions – after such a long slumber promptly raise red flags. These are indicators that something is happening beneath the surface, even if a major eruption isn’t guaranteed. The ground deformation, particularly the “sombrero” shape with uplift at the center and sinking around it, is a significant anomaly.
Time.news: The article highlights the use of seismic tomography,comparing it to a “CAT scan for the Earth.” Can you elaborate on this technique and how it’s helping scientists understand what’s happening beneath Uturuñcu?
Dr. Anya Sharma: Seismic tomography is a powerful tool. It uses seismic waves – the same waves produced by earthquakes – to create images of the Earth’s interior. Just like a medical CAT scan uses X-rays, seismic tomography uses seismic waves to map variations in density and composition. The speed at which seismic waves travel provides valuable information about the subsurface. In the case of Uturuñcu, it allowed researchers to identify the “sombrero” deformation and gain insight into the distribution of fluids and gases beneath the volcano. The fact that the deformation is linked to internal circulation of liquids and gases rather than a massive magma ascent makes it unique.
Time.news: The article mentions “internal circulation” within Uturuñcu. What does this mean, and why is it considered a “zombie” characteristic?
Dr. Anya Sharma: Well, the term “zombie volcano” is a bit evocative, but it’s used to describe volcanoes that show signs of reawakening without a clear pathway for large-scale magma ascent from deep within the Earth. Internal circulation refers to the movement of hot fluids and gases within shallow reservoirs beneath the volcano. This circulation can be driven by heat from deeper sources and cause seismic activity and ground deformation, even without a massive injection of fresh magma. It suggests that the volcano is being re-energized by internal processes, a bit like a zombie being reanimated, so the name.
Time.news: The report emphasizes that there may not be a “large-scale ascent of magma – at least for now.” Does there still exist a chance of eruption?
Dr. Anya Sharma: Of course. Even without a full-scale magma ascent currently, the activity is not stable. Things could change quickly. Volcanic systems are complex, and even if this activity is primarily driven by internal circulation, changes in pressure, temperature, or the introduction of new magma could lead to an eruption. The key here is it is less likely at the moment,but it is crucial to constantly monitor and analyze the data since “slow awakenings can turn brutal,” as the article states.
Time.news: The article also lists other volcanoes under close scrutiny, including Yellowstone and Phlegrean Fields. What makes monitoring supervolcanoes like these so crucial for safety and disaster prevention?
Dr. Anya Sharma: Supervolcanoes pose a unique and significant threat because their eruptions can have global consequences. A large eruption from Yellowstone or Phlegrean Fields could release massive amounts of ash and gases into the atmosphere, disrupting air travel, affecting climate, and causing widespread economic damage. The scale of the potential devastation is simply enormous. Therefore,continuous monitoring,detailed modeling,and emergency preparedness are absolutely essential to mitigate the potential risks.We have a better chance dealing if we monitor and plan for them better.
Time.news: For our readers who live near potentially active volcanoes,what steps can they take to prepare themselves and their families for a possible eruption?
Dr.Anya Sharma: Living near a volcano requires vigilance and preparedness. Firstly,stay informed about the volcano’s activity through local authorities and scientific sources like the USGS. Secondly, develop an evacuation plan that includes designated routes and assembly points. Have an emergency kit with essential supplies like food,water,medications,a radio,and flashlights.Most importantly, understand the risks and heed any warnings or evacuation orders issued by authorities. Also, knowing your community’s disaster preparedness plan can definitely help.
Time.news: What are the main pros and cons of monitoring “inactive” volcanoes?
Dr. Anya Sharma: The main pros are early warning of potential eruptions, improved volcano process understanding to reduce risk, and reduced economic losses from volcanic disasters. The main cons are the high cost of monitoring equipment and personnel, the potential for false alarms leading to economic disruption, and the difficulty in interpreting complex data to predict volcanic behavior.
Time.news: what are some of the most important things to understand to stay safe around volcanoes?
Dr. Anya Sharma: It’s crucial to be familiar with the volcano’s history, the types of hazards it poses (ash fall, lava flows, lahars – volcanic mudflows, pyroclastic flows), and the warning signs of an impending eruption. Stay informed, have a plan, and respect the power of these geological giants. International studies also help get a broader viewpoint of these systems since each system can have unique properties.
