Observations of Deformation

Volcano number:358041
Geodetic measurements?Yes
Deformation observation?Yes
Measurement method(s):InSAR
Duration of observation:April 2007 to July 2008
Characteristics of deformation:

Between April 2007 and July 2008, Chaitén showed 22 cm of subsidence. We are able to match the deformation pattern with either a collapsing dike, dip-slip faulting, or a combination of faulting and magma chamber deflation. The model prediction from the best fit model (a dike). The residual between the data and models is rather large (∼4–5 cm, perhaps reflecting additional unmodeled deformation sources.  Ref 1
