O'a Caldera

Observations of Deformation

Volcano number:221280
Geodetic measurements?Yes
Deformation observation?No
Measurement method(s):InSAR
Duration of observation:1997-2000, 2003-2010
Characteristics of deformation:

O’a Caldera is covered by┬áthe tracks of InSAR data processed by Biggs et al. (2011), however it is also completely submerged under Lake Shalla. As a result of this, no direct InSAR observations have been made of the caldera. The closest coherent regions to the lake, however, show no deformation.
Fumerolic activity is observed all around the lake.
