Bolivia’s Uturuncu volcano, dormant for over 250,000 years, shows signs of life like earthquakes and gas emissions, earning it the nickname “zombie” volcano. A new study using seismic tomography reveals that its activity is likely caused by geothermally heated fluids and gases beneath the surface, not imminent eruption. Researchers from China, the UK, and the U.S. say the findings help assess volcanic hazards and can aid in studying other seemingly inactive volcanoes.
