Observations of Deformation
|Duration of observation:||1995 - 2004|
|Inferred cause(s) of deformation:||Surface deposits|
|Characteristics of deformation:|
Novarupta is located at the edge of a broad region of uplift covering the vicinity of Trident, Martin and Mageik. Between 1992 – 2000, InSAR recorded uplift of this region at 5–10 mm/yr, and between 2000 – 2004 deformation continued at 4–7 mm/year. These interferograms also suggest localised subsidence of Novarupta, which has been attributed to thermoelastic contraction of the dome and thick ashflow tuff.
