Characteristics of deformation:

Metzger et al. (2011) present ENVISAT interferograms that reveal a transient uplift signal at the nearby Theistareykir central volcano with a maximum line-of-sight uplift of 3 cm between summers of 2007 and 2008. The authors assume the deformation is linear and due to an inflating Mogi source. The study is focused on the locking depth and slip-rate of the Húsavík Flatey fault but models the inflation of Theistareykir.
