Theistareykjarbunga

Volcano number:373090
Region:Iceland and Arctic Ocean
Country:Iceland
Geodetic measurements?Yes
Deformation observation?Yes
Measurement method(s):InSAR, GPS - continuous, GPS - campaign, Levelling, Strainmeter, Tiltmeter, EDM
Duration of observation:
Inferred cause of deformation:Faulting/tectonics
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.

Sourced from FutureVolc (http://futurevolc.hi.is/volcanoes-and-monitoring): “Iceland: volcanoes and present long-term monitoring stations. The volcanic areas consist of volcanic systems, made of central volcanoes, calderas and fissure swarms. Western Eastern, and Northern volcanic zones marked (WVZ, EVZ, NVZ) are located on the divergent plate boundary between the North-American and Eurasian plates. Iceland’s most active volcanoes are Grímsvötn (G) and Bárðarbunga (B) under the Vatnajökull ice cap, Katla (K) under Mýrdalsjökull ice cap, and Hekla (H). Eyjafjallajökull vocano is labelled E”.
