Observations of Deformation
|Duration of observation:||1993-1999|
|Inferred cause(s) of deformation:||Magmatic|
|Characteristics of deformation:|
We detect inflation of Cerro Hudson volcano following its 1991 eruption, and use spherical and non-spherical models to constrain the source of deformation to be between 4 and 8 km below sea level. We measure the rate of deformation to be about 5 cm/year in the radar line-of-sight, and infer that the maximum deformation could exceed 10 cm/year in the center of the caldera Ref 1.
