Observations of Deformation
| Volcano number: | 311080 |
|---|---|
| Region: | Alaska |
| Country: | United States |
| Geodetic measurements? | Yes |
| Deformation observation? | Yes |
| Measurement method(s): | InSAR |
| Duration of observation: | 2004 - 2009 |
| Inferred cause(s) of deformation: | Magmatic |
| Characteristics of deformation: | During October – November 2005, an episode of surface uplift (3 – 5 cm) occurred encompassing both Tanaga and Takawanga volcanoes. The broad region of uplift is modelled as a pressurising magma reservoir using a point source or a shallow-dipping prolate source that is elongate in the east-west direction. The source depth is inferred to be 5 – 8 km with a volume increase of 0.002 – 0.008 km³. |
