US EditionZombie volcano stirs after 250,000 years of dormancy: Scientists explore
- Scientists reported on April 28 that Bolivia's Uturuncu volcano, dormant for over 250,000 years, shows signs of internal activity like gas plumes and earthquakes.
- This activity results from forces beneath Uturuncu causing a 150-kilometer-wide region near its summit to rise and fall in a sombrero shape, linked to a massive magma reservoir called the Altiplano-Puna Magma Body.
- Researchers utilized data from over seventeen hundred earthquakes recorded from 2009 through 2012 to generate detailed images of the shallow crust beneath Uturuncu, revealing that the volcano's activity is driven by its hydrothermal system instead of ascending magma.
- Dr. Mike Kendall of Oxford explained, "a bad sign would be an increase in seismicity" migrating from deep to shallow depths, but he reassured that "we're not seeing anything like that," indicating no immediate eruption risk.
- These findings suggest Uturuncu is unlikely to erupt soon while guiding scientists on assessing other zombie volcanoes worldwide that show geothermal activity but remain dormant.

Scientists Probe ‘Zombie Volcano’ Stirring Back To Life
Imagine a volcano that hasn’t erupted in over 250,000 years—but still rumbles, breathes steam, and messes with the land around it. Meet Uturuncu, Bolivia’s so-called “zombie volcano.” But this mountain isn’t gearing up for a fiery comeback—at least not yet. A recent study in PNAS revealed that Uturuncu’s spooky behavior isn’t from magma on the move. Rather, a deep and complex system of hot fluids, gas, and briny steam bubbling through undergroun…
Zombie volcano stirs after 250,000 years of dormancy: Scientists explore
The Uturuncu volcano in Bolivia's Andes Mountains, dormant for 250,000 years, is exhibiting warning signs of a potential eruption that could threaten lives and cause destruction. Uturuncu, the highest mountain in southwestern Bolivia, caused a region near its summit—about 150 kilometers (93 miles) wide—to rise and fall, creating a sombrero-like shape. Over 1,700 recent earthquakes have prompted scientists to study Uturuncu. By integrating satell…

illuminem.comScientists explore the anatomy of a ‘zombie volcano’ that’s showing signs of activity
Can a volcano rise from the dead? Uturuncu, a lofty peak in the Central Andes mountain range, is what’s known as a “zombie volcano.” It hasn’t erupted for more than 250,000 years, but it nonetheless shows signs of activity similar to those seen in active volcanoes, such as gas plumes and earthquakes. Satellite radar imagery taken more than two decades ago of Uturuncu — the tallest mountain in southwestern Bolivia — showed that forces inside the …
