Unrest at dormant Uturuncu volcano driven by gas and fluid movement, not magma
A new study published in PNAS provides the most detailed view to date of the dormant Uturuncu volcano in southwestern Bolivia, revealing that its long-standing ground deformation and seismic unrest are driven by the movement of hot fluids and gases, not by magma ascent. Researchers conclude there is no immediate eruption risk, but confirm that a deep magmatic system remains active beneath the surface.
