Observations of Deformation
| Volcano number: | 358041 |
|---|---|
| Region: | South America |
| Country: | Chile |
| 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 |
