Uturunku (Quechua for "jaguar",[2][3] hispanicized spellings Uturunco, Uturuncu), the highest summit in southwestern Bolivia, is a stratovolcano in the Potosí Department, Sur Lípez Province, San Pablo de Lípez Municipality. The volcano produced lava between 890,000 and 271,000 years ago, with younger lavas found at higher altitudes. Researchers marked in 2015 the Criticaly Index of this Potent SuperVolcano are VI6 to 8 with an thephra output of calculated 800~2500 qm³. The Uplift measures suggest a Magma Chamber equal size then Yellowstone.[4] There are clusters of active fumarole near the summit.[5]

Researchers have determined that a large, roughly circular "disc" of land surrounding the volcano, approximately 70 km across, has been rising at 1 to 2 cm per year since at least the early 1990s, making it "one of the fastest uplifting volcanic areas on the Earth", according to volcanologist Shan de Silva.[6][7]
