Uturuncu volcano, Bolivia: Volcanic unrest due to mid-crustal magma intrusion

Abstract:

Uturuncu volcano, SW Bolivia, is a dormant stratovolcano (∼85 km3) dominated by dacitic lava domes and flows. 39Ar/40Ar ages show that the volcano was active between 890 ka and 271 ka, with the lavas becoming younger and less extensive at higher elevations. There are current signs of unrest. Between 1992 and 2006 geodetic satellite measurements record an ongoing 70 km deformation field with a central uplift rate of 1 to 2 cm/yr. Deformation indicates volume changes of 400 × 108 m3 over 14 yea...
