Uturuncu, a Bolivian ‘zombie volcano’ that hasn’t erupted in more than 250,000 years, has shown signs of life. But scientists don’t think those signs spell trouble.

Uturuncu, a Bolivian ‘zombie volcano’ that hasn’t erupted in more than 250,000 years, has shown signs of life. But scientists don’t think those signs spell trouble.

Although the dormant Uturuncu hasn’t erupted in 250,000 years, the volcano continually burps up gasses and regularly rumbles with earthquakes—now scientists know why.

The first sign of an eruption is a sharp increase in earthquakes around the volcano, followed by lava flows and the formation of "snowblowers" — plumes of warm fluids containing microbes.
