Observations of Deformation

Volcano number:355838
Region:
Country:Bolivia
Geodetic measurements?Yes
Deformation observation?Yes
Measurement method(s):InSAR
Duration of observation:1992-2011
Inferred cause(s) of deformation:Magmatic
Characteristics of deformation:

Between 1992 and 2011, an area around Uturuncu volcano over 70 km across has been uplifting at an approximately constant rate of 1 cm/year. The uplifting area is surrounded by a ‘moat’ that is subsiding at ~0.2 cm/year (Henderson and Pritchard, 2013). Various explanation have been proposed for this deformation, including melt rising from the lower to mid crust, lateral migration of melt in the mid crust, and diapir formation (Henderson and Pritchard, 2013)
