Observations of Deformation
Volcano number: | 354006 |
---|---|
Region: | South America |
Country: | Peru |
Geodetic measurements? | Yes |
Deformation observation? | Yes |
Measurement method(s): | InSAR |
Duration of observation: | 1993-2010 (ERS/Envisat), 2007-2011 (ALOS) 2012-2015 (TSX) |
Inferred cause(s) of deformation: | Magmatic, Faulting/tectonics |
Characteristics of deformation: | Between 1993 and 1998, an area centred 7 km north of Sabancaya was uplifting at a rate of 2 cm/year (Pritchard & Simons 2002). The deformation pattern was well fit by an inflating point source at 11-13 km depth, inferred to be a magmatic source. |
