The most recent activity at Bardarbunga occurred in 2014 with the injection of a 45-km-long regional dike was emplaced over a period of 2 weeks in August 2014. Gudmundsson et al. (2014) show that the dike initiated close to the Bardarbunga Volcano but gradually extended to the northeast until it crossed the boundary between the East Volcanic Zone (EVZ) and the North Volcanic Zone (NVZ). The eruption was heavily monitored using InSAR analysis, in conjunction with GPS measurements and earthquake seismicity, has been instrumental in the continued monitoring of Bárðarbunga volcanic system since the onset of unrest. |
