Scientists spark fears as 'zombie' volcano dormant for 250,000 years shows signs of eruption

Anyone planning a trip through South America may want to keep one eye on the news, as one a 'zombie' volcano in the region is currently showing signs of increased activity.

Located in the south west of Bolivia is the sleeping giant Uturuncu, a volcano which hasn't erupted in over 250,000 years. Given that Uturuncu's last eruption is nearly as old as anatomically modern humans, you'd think its pretty safe to assume the volcano is unlikely to explode any time soon, right?

Well, not entirely, as the volcano has been showing signs of a possible eruption for the past couple of decades, which has left numerous scientists stumped.

So, why is a volcano which is considered technically dead currently acting up and should nearby residents be packing a go bag?

Uturuncu has been showing increased signs of seismic activity since the 1990s, with scientists noticing that the stratavolcano was taking on a 'sombrero like' shape as parts of the mountain were either rising or sinking.

Findings from the most recent study (published 28 April) on the volcano's activity revealed geographical changes were down to a deep underground reservoir of magma is releasing plumes of hot fluids and gases, which is causing the ground to deform. The thought of an underground lake of magma causing the ground to become warped under our feet certainly sounds pretty terrifying, but researchers were also keen to stress it was unlikely to erupt anytime soon.

Which will certainly be music to the ears of anyone who lives in close proximity to the volcano.

The research, which involved creating high-resolution imaging of volcanic plumbing inside Uturuncu, could also be applied to other volcanoes when it comes to assessing eruption risks.

"Our results show how linked geophysical and geological methods can be used to better understand volcanoes, and the hazards and potential resources they present," co-author Professor Mike Kendall, from the University of Oxford said of the findings (via MEN).

Professor Kendall's optimism was also backed up by Cornell University's Professor Matthew Pritchard, who explained how their research could be applied to '1,400 potentially active volcanoes'.

"And to the dozens of volcanoes like Uturuncu that aren't considered active but that show signs of life – other potential zombie volcanoes," he continued.

"When people look at volcanoes, they’re like, 'Oh, if it’s not going to erupt, we’re not interested in it.' But actually volcanoes that look dead on the surface are not dead underneath."
